Prepare.
Another technique disclosed in the present specification is a server connected to a terminal device and a plurality of printers having different executable printing conditions. The server includes a storage control unit, an identification information acquisition unit, a target data acquisition unit, a screen data supply unit, a setting information acquisition unit, a print data generation unit, and a print data supply unit. The storage control unit stores, in the memory, original data for providing any of the plurality of setting screens corresponding to the plurality of printers to the user of the terminal device. Each of the plurality of setting screens is a screen that allows the user to specify the contents of each setting item that conforms to printing conditions that can be executed by the corresponding printer. The identification information acquisition unit acquires specific printer identification information for identifying a specific printer among the plurality of printers from the terminal device. The target data acquisition unit acquires target data for printing. The screen data supply unit supplies, to the terminal device, specific setting screen data representing a specific setting screen corresponding to the specific printer identified by the acquired specific printer identification information based on the original data. The setting information acquisition unit acquires setting information indicating the contents of each specified setting item specified by the user via the specific setting screen from the terminal device. The print data generation unit generates print data having a format that can be interpreted by a specific printer, using the contents of each designated setting item indicated by the setting information and the target data. The print data supply unit supplies print data to a specific printer.

  In this configuration, the server does not need to install a printer driver for generating print data using the target data in the terminal device in order for the server to generate print data that can be interpreted by a specific printer. The server also supplies the terminal device with specific setting screen data for designating the contents of each setting item that matches the printing conditions that can be executed by the specific printer. For this reason, the terminal device can display a specific setting screen using specific setting screen data. The user can specify the content of each setting item that matches the printing conditions that can be executed by a specific printer via a specific setting screen. The server generates print data using the contents of each setting item designated by the user and the target data, and supplies the print data to a specific printer. As a result, the specific printer executes printing using the print data. According to the above configuration, it is possible to realize printing according to the contents of each setting item designated by the user (that is, the printing conditions desired by the user).

  The original data may include, for each printer model, model printing condition information indicating a model printing condition that is a printing condition supported by the model. The screen data supply unit specifies the contents of each setting item that conforms to the specific model printing condition indicated by the specific model printing condition information based on the specific model printing condition information corresponding to the specific printer model. The specific setting screen data representing the specific setting screen allowed for the user may be supplied to the terminal device.

  The storage control unit may include a current printing condition information acquisition unit that acquires, from each of the plurality of printers, current printing condition information indicating a current printing condition that is a printing condition currently executable by the printer. . The original data may further include current print condition information of the printer associated with the printer identification information of the printer for each of the plurality of printers. The screen data supply unit, based on the specific model printing condition information and the specific current printing condition information associated with the acquired specific printer identification information, the specific model printing condition, The specific setting screen data representing the specific setting screen that allows the user to specify the content of each setting item that matches the specific current printing condition indicated by the specific current printing condition information. May be supplied to the terminal device. Printing conditions that can be executed by the printer may change over time. For example, normally, even if the printer can perform color printing and monochrome printing, color printing cannot be executed if there is no remaining color material for color printing. According to this configuration, the server can supply setting screen data for designating the content of each setting item that conforms to the printing conditions that the printer can currently execute to the terminal device. Therefore, the user can specify the contents of each setting item that matches the printing conditions that can be currently executed by a specific printer.

  The screen data supply unit includes a setting field for the user to specify the contents of each setting item that conforms to the specific current printing condition among all the setting items that conform to the specific model printing condition. Supplying the terminal device with the specific setting screen data representing the specific setting screen that does not include a setting field for the user to specify the content of each setting item that does not conform to the specific current printing condition. Also good. If the user can specify the contents of each setting item that does not conform to the printing conditions currently executable by the specific printer, that is, the contents that cannot be executed by the specific printer (for example, color printing), Since printing according to the contents is not executed (for example, monochrome printing is executed), the user may feel uncomfortable. According to the above configuration, the specific setting screen does not include a setting field for designating the content of each setting item that does not conform to the print conditions that can be executed by the specific printer. Therefore, although the user has specified contents that cannot be executed by a specific printer, the occurrence of an uncomfortable event for the user can be suppressed by not performing printing according to the contents.

  When new current printing condition information is acquired from each of the plurality of printers, the storage control unit acquires the current printing condition information from the printer instead of the current printing condition information associated with the printer identification information of the printer. The new current printing condition information may be stored in the memory. According to this configuration, the server can update the current printing condition information, and can supply the setting screen data based on the latest current printing condition information.

  Each model printing condition information includes, for each setting item conforming to the model printing condition of the model, field data indicating a setting field for the user to specify the contents of the setting item, and a position where the setting field is to be arranged And position data indicating. The screen data supply unit may include a generation unit that generates the specific setting screen data. The generation unit may generate the specific setting screen data using each field data and each position data included in the specific model printing condition information.

  Each model printing condition information may include option information indicating options of the contents of the setting items that match the model printing conditions of the model. The screen data supply unit may include a generation unit that generates the specific setting screen data. The generation unit may generate the specific setting screen data using specific option information included in the specific model printing condition information. According to this configuration, for example, specific setting screen data for the user to specify the contents of each setting item from the options can be generated.

  The storage control unit may include a default printing condition information acquisition unit that acquires default printing condition information indicating a default printing condition currently set for the printer from each of the plurality of printers. The original data may include default printing condition information of the printer associated with the printer identification information of the printer for each of the plurality of printers. The screen data supply unit may include a generation unit that generates the specific setting screen data. Based on the specific default print condition information associated with the acquired specific printer identification information, the generation unit describes the specific default print condition described by the specific default print condition information described above. The specific setting screen data representing the setting screen may be generated. According to this configuration, the user can specify the contents of each setting item while referring to the default printing conditions of a specific printer.

  The present specification further discloses a printer connected to the server. The printer includes a current print condition information supply unit, a print data acquisition unit, and a print execution unit. The current printing condition information supply unit supplies, to the server, printer identification information of the printer and current printing condition information indicating the current printing conditions that are currently executable by the printer when the printer is turned on. To do. In addition, when the current printing condition of the printer changes, the current printing condition information supply unit supplies printer identification information of the printer and new current printing condition information indicating the changed current printing condition to the server. The print data acquisition unit acquires print data from the server. The print execution unit executes printing using the print data.

  Note that a control method, a computer program, and a computer-readable storage medium storing the computer program for realizing the server are also novel and useful. In addition, a control method, a computer program, and a computer-readable storage medium storing the computer program for realizing the printer are novel and useful.

  Embodiments will be described with reference to the drawings. As shown in FIG. 1, the network system 2 includes a server 10, a PC 60, and a plurality of printers 70, 80, 90. The server 10 is connected to the LAN 4. The PC 60 is portable. The PC 60 is temporarily connected to a LAN 8 different from the LAN 4. The PC 60 is communicably connected to the server 10 via the LANs 4 and 8 and the Internet 6. The first printer 70, the second printer 80, and the third printer 90 are connected to the LAN 8. The printers 70, 80, and 90 are connected to the server 10 through the LANs 4 and 8 and the Internet 6 so that they can communicate with each other. The printer ID of the first printer 70 is “PRI70”, the printer ID of the second printer 80 is “PRI80”, and the printer ID of the third printer is “PRI90”.

(Server configuration)
The server 10 includes a memory 20, a control unit 30, and a network interface 50. The control unit 30 executes various processes according to the server program 22 stored in the memory 20. When the control unit 30 executes processing according to the server program 22, the storage control unit 32, the identification information acquisition unit 36, the target data acquisition unit 38, the screen data supply unit 40, the setting information acquisition unit 44, the print data generation unit 46, In addition, the function of the print data supply unit 48 is realized. The storage control unit 32 includes a current printing condition information acquisition unit 34 and a default printing condition information acquisition unit 35. The screen data supply unit 40 includes a generation unit 42.

  The memory 20 stores a server program 22 that is executed by the control unit 30. The memory 20 includes a model information storage area 24, a printer information storage area 26, and a layout data storage area 28.

  The model information storage area 24 stores a plurality of model information 110 and 130 (see FIG. 2). One model information 110 and 130 is information corresponding to one model of the printer. The storage control unit 32 of the control unit 30 acquires model information of each model from the server of the printer vendor of each model via, for example, the Internet 6 and stores it in the model information storage area 24. Alternatively, for example, the storage control unit 32 acquires model information from a medium storing model information of each model, and stores the model information of each model in the model information storage area 24. Alternatively, for example, the storage control unit 32 acquires model information of each model from each of the printers 70 to 90 and stores the model information of each model in the model information storage area 24.

(Contents of model information)
As shown in FIG. 2, information related to a printer of a model whose model name 112 is “AAA” is registered in the model information 110. Information registered in the model information 110 is classified into model printing condition information 120, interpretable data format information 122, and layout data information 124. The model printing condition information 120 is information indicating printing conditions supported by the model “AAA”. The model printing condition information 120 is information in which the item 114, the option 116, and the content 118 are associated with each other.

  In the model printing condition information 120, for example, “YES” of the option 116 is associated with the “stapler” of the item 114. This means that a printer for the model “AAA” can be equipped with a facility for executing a function (stapler function) of binding a print medium after printing with a stapler. That is, among the printers of model “AAA”, there are printers in which equipment for executing the stapler function is installed, and there are printers in which the equipment is not installed. The content 118 indicates the content of each setting item of the printing conditions supported by the printer of the model “AAA”, and means an option that can be selected by the user. For example, “ON, OFF” of the content 118 associated with “stapler” is an option from which the user can select printing (ON) for executing the stapler function and printing (OFF) for not executing the stapler function. It means that there is. As will be described in detail below, the “options selectable by the user” shown in the contents 118 vary depending on the current state of each printer 70 and the like.

  As in the above-described stapler function, “YES” of the option 116 is associated with an item that changes whether or not it can be executed by each printer. For example, “YES” of option 116 is also associated with “duplex printing” of item 114. This means that a printer for executing the double-sided printing function can be installed in the printer of the model “AAA”. In addition, “single-sided, long-sided binding, single-sided binding” associated with “double-sided printing” means that various methods for executing the double-sided printing function are options that can be selected by the user.

  On the contrary, the item 114 (“color”, “resolution”, “original direction”, and “paper size”) associated with “NO” in the option 116 adds special equipment to the printer of the model “AAA”. Even if it is not installed, it is an item that can be executed by the printer of the model “AAA”. “Color, monochrome” associated with “color” means that color printing and monochrome printing are options that the user can select. Similarly, “300 dpi, 600 dpi, 1200 dpi” associated with “resolution” is a user-selectable option of printing at 300 dpi resolution, printing at 600 dpi resolution, and printing at 1200 dpi resolution. Means. “Horizontal, vertical” associated with “original direction” means that printing in the horizontal direction of the printing medium and printing in the vertical direction of the printing medium are options that the user can select. “LETTER, A4, B4” associated with “paper size” allows the user to select LETTER size printing medium printing, A4 size printing medium printing, and B4 size printing medium printing. Means an option. The model printing condition information 120 can also be said to be information indicating printing conditions that can be executed by the printer of the model “AAA”.

  In the content 118 associated with the interpretable data format information 122, information indicating the format of data that can be interpreted by the printer of the model “AAA” is registered. In the content 118 associated with the layout data information 124, a layout number for specifying layout data to be described later is registered.

  In the model information 130, information related to a printer of a model whose model name 132 is “BBB” is registered. Similar to the model information 110, the information registered in the model information 130 is classified into model printing condition information 140, interpretable data format information 142, and layout data information 144. Note that the model printing condition information 140 does not include “stapler” and “double-sided printing” unlike the model printing condition information 120 of the printer of the model “AAA”. This means that the printer of the model “BBB” cannot be installed with facilities for executing the duplex printing function and the stapler function. As can be seen by comparing the model information 110 and the model information 130, the number of items and the item contents (that is, the options that can be selected by the user) differ between the printer of the model “AAA” and the printer of the model “BBB”. . Accordingly, the supported printing conditions are different between the model “AAA” and the model “BBB”. FIG. 2 shows only model information 110 and 130 of two types of models “AAA” and “BBB”, but the model information storage area 24 further includes other various models (for example, “ CCC ") type information is stored.

  In the printer information storage area 26 (see FIG. 1), printer information of each printer 70 to 90 is stored. As will be described later, the storage control unit 32 acquires printer information from each of the printers 70 to 90 and stores the printer information of each of the printers 70 to 90 in the printer information storage area 26 (S606, 608, and 616 in FIG. 5). 618).

(Contents of printer information)
As shown in FIG. 3, the printer information 210 is printer information of the first printer 70 whose printer ID is “PRI70”. The printer information 210 includes a printer ID “PRI70” and a model name “AAA” indicating the model of the first printer 70. The printer information 210 further includes current printing condition information 218 and default printing condition information 220.

  The current printing condition information 218 indicates printing conditions that the first printer 70 can currently execute. The current printing condition information 218 is information in which the item 214 and the content 216 are associated with each other. The model of the first printer 70 is “AAA”. Therefore, the model information of the first printer 70 is the model information 110 of FIG. As shown in FIG. 2, in the model printing condition information 120 of the model “AAA”, “duplex printing” and “stapler” of the item 114 are associated with “YES” of the option 116. Therefore, it is not known from the model information 110 only whether the first printer 70 can execute the duplex printing function and the stapler function. As shown in FIG. 3, in the current printing condition information 218 of the first printer 70, “Double-sided printing” of the item 214 and “Yes” of the content 216 are associated with each other. This means that the first printer 70 is currently equipped with equipment for executing the duplex printing function, and the first printer 70 can execute the duplex printing function. On the other hand, in the current printing condition information 218 of the first printer 70, “stapler” of the item 214 and “none” of the content 216 are associated with each other. This means that the first printer 70 is not currently equipped with equipment for executing the stapler function, and the first printer 70 cannot execute the stapler function.

  As shown in FIG. 2, in the model printing condition information 120 of the model “AAA”, “paper size” of the item 114 and “LETTER, A4, B4” of the content 118 are associated with each other. On the other hand, as shown in FIG. 3, in the current printing condition information 218 of the first printer 70, “paper size” of the item 214 and “A4, LETTER” of the content 216 are associated with each other. This is because the first printer 70 is capable of printing on LETTER, A4, and B4 size print media, but currently only the LETTER and A4 size paper cassettes are set in the first printer 70. Indicates that no B4 size paper feed cassette is set. That is, the first printer 70 is currently capable of printing only on print media of LETTER and A4 sizes. Note that “A4 is present and LETTER is present” associated with “Number of remaining sheets” in item 214 indicates that the A4 size print medium remains in the paper feed cassette and the LETTER size print medium remains in the paper feed cassette. Indicates that it remains.

  The printing conditions currently executable by the first printer 70 can change. For example, when a facility for executing the stapler function is installed in the first printer 70, the first printer 70 can execute the stapler function. As will be described later, the first printer 70 supplies new current printing condition information to the server 10 when the currently executable printing conditions change (see S612 in FIG. 5). When the server 10 acquires new current printing condition information, the server 10 updates the current printing condition information 218 with new current printing condition information.

  The default printing condition information 220 indicates default printing conditions currently set for the first printer 70. The default printing condition information 220 is information in which the item 214 and the content 216 are associated with each other. The default printing conditions are printing conditions designated in advance by the user for the first printer 70. In other words, the first printer 70 executes printing according to the default printing conditions unless other printing conditions are specified at the time of printing.

  Although not shown in detail in FIG. 3, the printer information storage area 26 also stores the printer information of the second printer 80 and the printer information of the third printer 90. In this embodiment, the model of the second printer 80 is “BBB”, and the model of the third printer 90 is “CCC”.

  The layout data storage area 28 (see FIG. 1) stores a plurality of layout data 310 and 330 (see FIG. 4). One piece of layout data 310 and 330 is information corresponding to one type of printer. The storage control unit 32 of the control unit 30 may store the layout data of each model acquired from the server in the layout data storage area 28 as well as the model information 110 and 130 described above or acquired from the media. The layout data of each model may be stored in the layout data storage area 28, or the layout data of each model acquired from each printer 70 to 90 may be stored in the layout data storage area 28.

(Contents of layout data)
As shown in FIG. 4, the layout data 310 and 330 are assigned numbers “1” and “2”, respectively. This number corresponds to the layout data number shown in the layout data information 124 and 144 (associated with “layout data”) included in the model information 110 and 130 in FIG. That is, the layout data for the printer of the model “AAA” (for example, the first printer 70) is the layout data 310 of FIG. 4, and the layout data for the printer of the model “BBB” (for example, the second printer 80) is. This is the layout data 330 of FIG. The layout data storage area 28 further stores layout data for other models (for example, “CCC”).

  The layout data 310 for the printer of the model “AAA” includes field data 312 and position data 318. The field data 312 is data in which an item character string 314 and a box type 316 are associated with each other. The item character string 314 is a character string indicating each item 114 of the model printing condition information 120 of the corresponding model information (that is, the model information 110 of the model “AAA”). The item character string 314 further includes a character string “number of copies” which is not included in each item 114 of the model printing condition information 120. The box type 316 is information indicating the type of box displayed on the setting screen 500 (see FIG. 8) described later. In this embodiment, there are two types of boxes, a number selection type box and a character string selection type box. The number selection type box is a box for allowing the user to select an integer of 1 or more within a predetermined range. The character string selection type box is a box for allowing the user to select (specify) one option from two or more options selected in advance. The position data 318 is data indicating the position of the related field data 312 on the setting screen 500.

  Similar to the layout data 310, the layout data 330 includes field data 332 and position data 338. The field data 332 is data in which an item character string 334 and a box type 336 are associated with each other. The item character string 334 is a character string indicating each item of the model printing condition information 140 of the corresponding model information (model information 130 of the model “BBB” (see FIG. 2)). However, the item character string 334 includes a character string “number of copies” that is not included in each item of the model printing condition information 140. The item character string 334 does not include an item character string for which two or more options do not exist. For example, “color” in the model printing condition information 140 is associated with “monochrome”. That is, the printer of the model “BBB” can execute only monochrome printing. For this reason, the user cannot select other than monochrome printing (that is, there is no option). The character string of such an item is not included in the layout data 330.

(Printer configuration)
As shown in FIG. 1, the first printer 70 includes a control unit 72, a print execution unit 78, and a memory 77. The memory 77 stores a printer program 79 that is executed by the control unit 72. The control unit 72 executes various processes according to the printer program 79 stored in the memory 77. When the control unit 72 executes processing according to the printer program 79, the current printing condition supply unit 74 and the print data acquisition unit 76 are realized. The print execution unit 78 prints an image represented by the print data acquired by the print data acquisition unit 76. Note that the second printer 80 and the third printer 90 have the same configuration as the first printer 70. However, as described above, the printers 70, 80, and 90 are different in model and have different executable printing conditions.

(PC configuration)
The PC 60 includes an operation unit 62, a display unit 64, and a browser program 66. The operation unit 62 includes a keyboard and a mouse to be operated by the user. The display unit 64 is a display for displaying various information. A control unit (not shown) of the PC 60 can display various information acquired via the Internet 6 on the display unit 64 according to the browser program 66.

(Processes executed by each device in the network system)
Next, processing executed by the server 10, the PC 60, and the first to third printers 70 to 90 will be described with reference to FIG. The current printing condition supply unit 74 (see FIG. 1) of the first printer 70 supplies printer information 604 to the server 10 when the power of the first printer 70 is turned on (S602). The printer information 604 includes a printer ID “PRI70” of the first printer 70, current printing condition information (see reference numeral 218 in FIG. 3) of the first printer 70, default printing condition information (see reference numeral 220 in FIG. 3), including.

  The storage control unit 32 (see FIG. 1) of the server 10 acquires the printer information 604 supplied from the first printer 70 (S606). Specifically, the current print condition information acquisition unit 34 (see FIG. 1) acquires the current print condition information included in the printer information 604, and the default print condition information acquisition unit 35 (see FIG. 1) is included in the printer information 604. Get default print condition information. Next, the storage control unit 32 stores the printer information 604 acquired in S606 in the printer information storage area 26 (S608). As a result, the printer ID, the current printing condition information, and the default printing condition information are stored in the printer information storage area 26 in association with each other. At this time, if the printer information including the printer ID acquired in S606 has already been stored in the printer information storage area 26, the storage control unit 32 replaces the stored printer information (restores the stored printer information). The printer information 604 acquired in step S606 is stored in the printer information storage area 26.

  As described above, the current printing conditions of the first printer 70 can change. Further, for example, when the equipment for executing the double-sided printing function is removed, the first printer 70 cannot execute the double-sided printing function (first example). Further, for example, when the color material (ink, toner, etc.) for color printing runs out, the first printer 70 can execute only monochrome printing (second example). Further, for example, when the first printer 70 runs out of A4 size print media in the paper feed cassette, it cannot print on the A4 size print media (third example). When the current printing condition of the first printer 70 changes, the current printing condition supply unit 74 of the first printer 70 updates the printer information registered in its own memory 77 (S610). The current printing condition supply unit 74 further updates the printer information registered in itself when the default printing condition of the first printer 70 is changed by the user. Each time the current printing condition supply unit 74 updates its own printer information, it supplies the updated printer information 614 of the first printer 70 to the server 10 (S612). In the first example, the current printing condition supply unit 74 supplies the server 10 with the printer information 614 including the current printing condition information whose content associated with “double-sided printing” is “none”. In the second example, the current printing condition supply unit 74 supplies the server 10 with printer information 614 including current printing condition information whose content associated with “color” is “monochrome”. In the third example, the current printing condition supply unit 74 uses the server 10 to store the printer information 614 including the current printing condition information whose content associated with the “remaining number of sheets” is “No A4, with LETTER”. To supply.

  The storage control unit 32 of the server 10 acquires the printer information 614 supplied from the first printer 70 as in S606 (S616). Next, the storage control unit 32 stores the printer information 614 acquired in S616 in the printer information storage area 26 (S618). At this time, since the printer ID “PRI70” included in the printer information 604 stored in S608 matches the printer ID “PRI70” included in the printer information 614 acquired in S616, the storage control unit 32 determines in S608. Instead of the stored printer information 604, the printer information 614 acquired in S616 is stored in the printer information storage area 26.

  Note that the same processing as the processing of S602 to S618 is performed between the server 10 and the second printer 80 and between the server 10 and the third printer 90.

  The user can supply a request for a print instruction screen from the PC 60 to the server 10 by operating the operation unit 62 of the PC 60. Specifically, the user activates the browser program 66 by operating the operation unit 62. Next, the user designates the URL of the server 10 by executing an operation according to the browser program 66. As a result, the PC 60 supplies the print instruction screen request 620 to the server 10.

  When acquiring the print instruction screen request 620, the control unit 30 of the server 10 supplies the print instruction screen data 624 to the PC 60 (S622). The print instruction screen data 624 is described in a data format that can be interpreted by the browser program 66 of the PC 60. For example, the print instruction screen data 624 is described in HTML (Hyper Text Markup Language), XML (Extensible Markup Language), or the like.

  The PC 60 causes the display unit 64 (see FIG. 1) to display the print instruction screen 400 represented by the print instruction screen data 624 acquired from the server 10 according to the browser program 66 (see FIG. 1). As shown in FIG. 6, the print instruction screen 400 includes an area 402 for allowing the user to specify a printer ID and areas 404 and 406 for specifying a target file to be printed. The user can input (designate) the printer ID of the printer to be printed in the area 402 by operating the operation unit 62. The user can further specify the URL of the target file in the area 404 by operating the operation unit 62. For example, when a file stored in an external server is set as a target file, the user inputs the URL of the target file in the external server in the area 404. Further, for example, when a file stored in the PC 60 is set as the target file, the user inputs the URL of the target file in the PC 60. Note that when the file stored in the PC 60 is the target file, the user can select the reference button in the area 406. In this case, the hierarchical relationship between each folder and each file in the PC 60 is displayed, and the user can select a target file based on the hierarchical relationship. In this case, the URL of the target file in the PC 60 selected by the user is automatically input in the area 406. The user can operate the “OK” button 408 after designating the target file.

  As illustrated in FIG. 5, when the “OK” button 408 is operated by the user, the PC 60 supplies the server 10 with the printer ID and file information 626 specified by the user. When the URL is input to the area 404 by the user, the PC 60 supplies the URL input by the user to the server 10 as the file information. On the other hand, when the URL is set in the area 406, the PC 60 acquires the target file in the PC 60 based on the URL input in the area 406. Next, the PC 60 supplies the acquired target file itself to the server 10 as the above file information.

  The control unit 30 of the server 10 acquires the printer ID and file information 626 supplied from the PC 60 (S628). Specifically, the identification information acquisition unit 36 (see FIG. 1) of the control unit 30 acquires the printer ID supplied from the PC 60. Further, the target data acquisition unit 38 (see FIG. 1) of the control unit 30 acquires file information supplied from the PC 60. If the file information is the URL of the target file, in S628, the target data acquisition unit 38 accesses another server specified by the URL and acquires the file identified by the URL. If the file information is the target file itself, in S628, the target data acquisition unit 38 acquires the target file by acquiring the file information 626 supplied from the PC 60. Next, the generation unit 42 (see FIG. 1) of the server 10 executes setting screen data generation processing (S630). Subsequently, the screen data supply unit 40 (see FIG. 1) of the server 10 supplies the generated setting screen data 634 to the PC 60 (S632). The setting screen data 634 is also described in a data format that can be interpreted by the browser program 66 of the PC 60.

(Setting screen data generation process executed by the server)
With reference to FIG. 7, the setting screen data generation process executed in S630 of FIG. 5 will be described. The generation unit 42 of the server 10 selects a printer associated with the printer ID acquired in S628 of FIG. 5 from among a plurality of printer information 210 and the like (see FIG. 3) stored in the printer information storage area 26. Identify information. In the following, the description will be continued by taking as an example the case where the printer ID “PRI70” of the first printer 70 is acquired in S628. Accordingly, the printer information 210 of the first printer 70 is specified. Next, the generation unit 42 specifies the content 216 (see FIG. 3) (that is, the model name) associated with the “printer model name” included in the specified printer information 210 (S702). By this. The model “AAA” of the first printer 70 is specified.

  Next, the generation unit 42 is associated with the model name “AAA” identified in S702 from among a plurality of model information 110, 130, etc. (see FIG. 2) stored in the model information storage area 24. The model information 110 is specified (S704). Subsequently, the generation unit 42 specifies the layout number “1” associated with the “layout data” among the items included in the model information 110 specified in S704. Then, the generation unit 42 specifies the layout data 310 with the specified layout number “1” from the plurality of layout data 310, 330, etc. (see FIG. 4) stored in the layout data storage area 28. (S706). Next, the generation unit 42 edits the layout data using the printer information 210 specified in S702 (S708).

  In the processing of S708, specifically, the generation unit 42 edits the field data 312 of the layout data 310 using the current printing condition information 218 included in the printer information 210 of the first printer 70. Specifically, the generation unit 42 deletes items from the field data 312 that cannot provide options to the user based on each piece of information in the current print condition information 218. For example, in the current printing condition information 218, since the item 214 “stapler” is associated with the content 216 “none” (that is, the first printer 70 cannot execute the stapler function), the generation unit 42 , Item character string “stapler” from field data 312, box type “character string selection” associated with “stapler”, position data “fifth line” associated with “stapler”, Is deleted. In this case, the generation unit 42 changes “line 6” in the position data 318 associated with “paper size” in the item 314 to “line 5”, and associates it with the “original direction” in the item 314. “7th line” of the position data 318 is changed to “6th line”. That is, the generation unit 42 corrects the position data 318 so that even if the item “stapler” is deleted, no blank can be created between other items.

  Also, for example, in the current printing condition information 218, when “color” of the item 214 and “monochrome” of the content 216 are associated (that is, when the first printer 70 can execute only monochrome printing). The generation unit 42 deletes the item character string “color”, the box type “character string selection”, and “second line” from the field data 312. Also in this case, the generation unit 42 corrects the position data 318 so that no blank can be made between items.

  When S708 ends, the generation unit 42 includes the model information 110 (see FIG. 2) of the model “AAA” of the first printer 70 identified in S704, and the printer information 210 (see FIG. 2) of the first printer 70 identified in S702. 3), for each item of the layout data 310 of the model “AAA” of the first printer 70, the printing condition options that the printer can currently execute are described in the layout data 310 (S710).

  Specifically, in the processing of S710, the generation unit 42 first identifies one item (hereinafter referred to as “target item”) among the plurality of items of the layout data 310. Next, the generation unit 42 specifies the content (for example, color, monochrome) associated with the target item (for example, “color”) from the model printing condition information 120 of the model information 110. Further, the generation unit 42 specifies the content (for example, color, monochrome) associated with the target item (for example, “color”) from the current printing condition information 218 of the printer information 210. Accordingly, the generation unit 42 includes the contents of items supported by the model “AAA” of the first printer 70 (for example, color and monochrome) and the contents that can be executed by the first printer 70 (for example, color and monochrome). And you can know. In S <b> 710, the generation unit 42 selects contents that can be executed by the first printer 70 among the contents of each item supported by the model “AAA” based on the information specified for each target item. The process described as a character string is executed.

  For example, when the target item is “color”, “color, monochrome” is specified from the model printing condition information 120 of the model information 110 and the current printing condition information 218 of the printer information 210. Therefore, the generation unit 42 can know that the first printer 70 can currently execute both color printing and monochrome printing supported by the model “AAA” of the first printer 70. In this case, the generation unit 42 describes “color” and “monochrome” as the character strings of options of the box type “character string selection” associated with the item “color” of the layout data 310.

  For example, when the target item is “double-sided printing”, “single-sided, long-sided binding, single-sided binding” is specified from the model printing condition information 120 of the model information 110, and the current printing condition information 218 of the printer information 210 is specified. "Yes" is identified from the above. Therefore, the generation unit 42 can know that the first printer 70 can currently execute the duplex printing function supported by the model “AAA” of the first printer 70. In this case, the generation unit 42 describes “single-sided, long-sided binding, single-sided binding” as a character string of a box option corresponding to the item “double-sided printing” of the layout data 310.

  For example, when the target item is “paper size”, “LETTER, A4, B4” is identified from the model printing condition information 120 of the model information 110, and “A4” is identified from the current printing condition information 218 of the printer information 210. , LETTER "is specified. Further, the generation unit 42 specifies “A4 exists, LETTER exists” associated with “the remaining number of sheets” from the current printing condition information 218 of the printer information 210. By referring to these pieces of information, the generation unit 42 can currently use the first printer 70 among the print medium sizes “LETTER, A4, B4” supported by the model “AAA” of the first printer 70. The size of the print medium “LETTER, A4” can be known. In this case, the generation unit 42 describes “LETTER, A4” as a character string of options corresponding to the box of the item “paper size” of the layout data 310, and the first printer 70 currently has a print medium that cannot be used. The size “B4” is not described.

  For example, when the target item is “original direction”, “horizontal, vertical” is specified from the model printing condition information 120 of the model information 110. However, the current print condition information 218 of the printer information 210 has no item corresponding to “original direction”. In this case, the generation unit 42 describes “horizontal, vertical” as the character string of the box option corresponding to the item “original direction” of the layout data 310.

  For example, when the target item is “number of copies”, the box type associated with the item “number of copies” is “number selection” as shown in FIG. In this case, the generation unit 42 describes each integer of 1 or more as a character string of box options corresponding to the item “number of copies” of the layout data 310.

  In S710, the generation unit 42 further reads the default print condition information 220 of the printer information 210. The generation unit 42 arranges the character string of the content indicated by the default print condition information 220 at the head of the character string of the options described for each target item. For example, in the default printing condition information 220, since “color” is “color”, “color” of “color, monochrome” which is an option of “color” is arranged at the head. As a result, the setting screen 500 (see FIG. 8) is displayed in a state where “color” is described in the box corresponding to “color”. Similarly, the generation unit 42 determines the arrangement of the option character strings so that the boxes corresponding to the other items are displayed in a state where the default printing conditions are described.

  When S710 ends, the generation unit 42 generates setting screen data having a data format that can be interpreted by the browser program 66 of the PC 60, using the layout data changed in S706 and S708 (S712). That is, the generation unit 42 uses the character string 314 (see FIG. 4) of the layout data item after the change and the character string of the option described in S710 as the position data 318 (see FIG. 4) of the layout data after the change. The setting screen data is generated so as to be arranged at the position (row) indicated by ().

  FIG. 8 shows a setting screen 500 represented by the setting screen data generated in S712. A position corresponding to “number of copies” of the setting item 508 is displayed in correspondence with a number selection box 502. The user can designate the number of copies by operating the button in the box 502. Each box 504 for character string selection is displayed at each position corresponding to each item (for example, “color”, “resolution”, etc.) other than “number of copies” of the setting item 508. In the initial state of the setting screen 500 (that is, the state in which the setting screen 500 is first displayed on the PC 60), each box 504 has default printing conditions indicated by the default printing condition information 220, that is, options described for each target item. The character string arranged at the top of the character string is displayed. When the user operates the button in the box 504, a list of options described in S710 of FIG. 7 is displayed on the setting screen 500. The user can select (specify) one option via the setting screen 500.

  The PC 60 displays the setting screen 500 (see FIG. 8) represented by the setting screen data 634 on the display unit 64 according to the browser program 66. The user can select (specify) the contents of each setting item by operating the operation unit 62. When the user operates the “OK” button 506 on the setting screen 500, the PC 60 supplies setting information 636 to the server 10 as shown in FIG. 5. The setting information 636 includes the contents displayed on the setting screen 500 (that is, the contents of each setting item selected by the user) when the “OK” button 506 is operated.

  The setting information acquisition unit 44 (see FIG. 1) of the server 10 acquires the setting information 636 supplied from the PC 60 (S638). Next, the print data generation unit 46 (see FIG. 1) generates print data using the setting information 636 acquired in S638 and the target file acquired in S628 (S640). Specifically, the print data generation unit 46 first specifies the printer information 210 (see FIG. 3) stored in the printer information storage area 26 in association with the printer ID “PRI70” acquired in S628. Next, the print data generation unit 46 specifies the content “AAA” of the “printer model name” included in the specified printer information 210. Further, the print data generation unit 46 specifies the model information 110 (see FIG. 2) stored in the model print condition information storage area 24 in association with the specified printer model name “AAA”. Next, the print data generation unit 46 specifies interpretable data format information 122 included in the model information 110. The print data generation unit 46 converts the target file acquired in S628 into image data having the data format indicated by the interpretable data format information 122 (that is, data having a data format that can be interpreted by the first printer 70). Next, the print data generation unit 46 generates print data including the image data generated in S640 and the setting information 636 acquired in S638. Further, the print data generation unit 46 associates the generated print data with the printer ID “PRI70” acquired in S628 and stores them in the memory 20. If the target file acquired in S628 is already in a data format that can be interpreted by the printer, such as a PDF file, for example, the print data generation unit 46 does not convert the data format of the target file itself. The print data generation unit 46 generates print data including the target file acquired in S628 and the setting information 636 acquired in S628.

  Each of the printers 70, 80, and 90 periodically inquires of the server 10 whether or not data to be processed by the printer is stored in the server 10 (polling 644). The polling 644 includes the printer ID of the printer that is the transmission source of the polling 644. When the server 10 acquires the polling 644, the server 10 determines whether the print data associated with the printer ID included in the polling 644 is stored in the memory of the server 10. If a positive determination is made in this determination processing, the server 10 supplies information 646 indicating that there is a job to the printer that is the transmission source of the polling 644 as a response to the polling 644. If the determination is negative in the above determination process, the server 10 supplies information indicating that there is no job (not shown) to the printer as the transmission source of the polling 644 as a response to the polling 644.

  When acquiring the information 646 indicating that there is a job, the transmission source printer of polling 644 supplies a job request 648 including its own printer ID to the server 10. On the other hand, when acquiring the information indicating that there is no job, the printer that is the transmission source of polling 644 does not supply the job request 648 to the server 10.

  When the server 10 acquires the job request 648, the print data including the print data associated with the printer ID included in the job request 648 (the image data generated in S640 and the setting information 363 acquired in S638). The print data stored in the memory 20 in S642 is supplied to the printer that is the transmission source of the job request 648 (S649).

  As a result, the print data acquisition unit 76 (see FIG. 1) of the first printer 70 acquires the print data stored in S642 (S651). The print execution unit 78 (see FIG. 1) of the first printer 70 executes printing using the print data acquired in S651. Specifically, the print execution unit 78 prints an image represented by the image data acquired in S651 on a print medium according to the setting information acquired in S651 (S652).

  This example has been described in detail. The server 10 generates print data including image data having a format that the printer can interpret the target file obtained from the PC 60 (S640 in FIG. 5). Therefore, printing of the target file can be realized without installing a printer driver for generating print data using the target data in the PC 60.

  The server 10 generates setting screen data using the model information 110 and 130, the printer information 210, and the layout data 310 and 330, and supplies the setting screen data to the PC 60 (S632 in FIG. 5). The PC 60 can display the setting screen 500 using the supplied setting screen data. The user can specify the content of each setting item that matches the printing conditions executable by the printer via the setting screen 500. The server 10 generates print data using the contents of each setting item designated by the user and the target file (S640 in FIG. 5), and supplies the print data to the printer (S649 in FIG. 5). As a result, the printer executes printing using the print data. According to the above configuration, it is possible to realize printing according to the contents of each setting item designated by the user (that is, the printing conditions desired by the user).

  When the printer information of each printer 70, 80, 90 is changed, the server 10 acquires the printer information (see S616 in FIG. 5). The server 10 stores the acquired printer information in the printer information storage area 26 (see S618 in FIG. 5). For this reason, the server 10 can supply the setting screen data for designating the contents of the setting items that match the printing conditions currently executable by the printers 70, 80, 90 to the PC 60. For this reason, the user can designate the content of each setting item that matches the printing conditions that can be currently executed by the printer.

  The server 10 stores setting screen data representing a setting screen 500 that does not include a box for the user to specify the content of each setting item (in this embodiment, “stapler”) that does not conform to the printing conditions currently executable by the printer. , Supplied to PC60. If the user can specify the contents of each setting item that does not conform to the printing conditions that can be currently executed by the printer, that is, the contents that cannot be executed by the printer (for example, color printing), depending on the contents. Since the printing is not executed, the user may feel uncomfortable. According to the present embodiment, the user designates contents that cannot be executed by the printer at the present time, but the printing according to the contents is not executed, thereby suppressing the occurrence of an uncomfortable event for the user. Can do.

  The server 10 generates setting screen data including options for each item in the setting screen data generation processing (see FIG. 7). As a result, the user can specify the content of each item by selecting one option from two or more options via the setting screen 500. The user can easily specify the printing conditions.

  In the setting screen 500, default print condition information is displayed in the initial state. For this reason, the user can specify the printing conditions while referring to the default printing condition information.

  The PC 60 is an example of a “terminal device”. The model information 110 and 130, the printer information 210, and the layout data 310 and 330 are examples of “original data”. The printer ID is an example of “printer identification information”. An item 508 and boxes 502 and 504 on the setting screen 500 are examples of “setting fields”. The model information specified in S704 of FIG. 7 is an example of “specific model information”, and the current printing condition information included in the printer information specified in S702 of FIG. 7 is an example of “specific current printing condition information”. The default print condition information included in the printer information specified in S702 of FIG. 7 is an example of “specific default print condition information”.

(Modification)
(1) The server 10 may not store the current printing condition information 218 and / or the default printing condition information 220 in the printer information 210. In this case, the server 10 may generate the setting screen data using the model information 110 or the like and the layout data 310 or the like. In other words, in this modification, the setting screen data corresponding to a plurality of printers of the same model is the same because the setting screen data does not change according to the current printing conditions of each printer.

(2) In this embodiment, the server 10 uses the current print condition information 218 among the items 114 of the model information 110 and 130 to display items that are not currently executable by the printer (“stapler” in this embodiment) as layout data. Delete from 310. However, the server 10 may generate setting screen data so that items that are not currently executable by the printer are displayed in a different manner from items that are currently executable by the printer. For example, the setting screen data may be generated so that an item that is not currently executable by the printer is displayed lighter than an item that is currently executable by the printer. Also in this case, it is preferable that the setting screen data is generated so that the user cannot select the contents of items that are not currently executable by the printer. The setting screen data of this modification also includes a setting field for the user to specify the contents of each setting item that conforms to the current printing conditions of the printer among all the setting items that conform to the model printing conditions indicated by the model information. Included in setting screen data representing a setting screen that does not include a setting field for the user to specify the contents of each setting item that does not conform to the current printing conditions of the printer.

(3) In this embodiment, the server 10 uses the layout data to generate setting screen data having a data format that can be interpreted by the browser program 66 (see FIG. 7). However, the server 10 may store setting screen data having a data format that can be interpreted by the browser program 66. In this example, setting screen data may be stored for each printer model. In this case, the server 10 may supply the setting screen data corresponding to the model “AAA” of the first printer 70 to the first printer 70 without being changed. In this example, the setting screen data for each model is an example of “original data”. Further, the server 10 may edit the setting screen data corresponding to the model “AAA” of the first printer 70 using the printer information 210 of the first printer 70. In this example, setting screen data for each model and printer information 210 for each printer are examples of “original data”. Alternatively, the server 10 may store, for each printer, setting screen data for designating the contents of each setting item of printing conditions that can be currently executed by the printer. In this case, when the server 10 acquires each printer information from each printer, the server 10 may edit the setting screen data of each printer.

(4) In this embodiment, the server 10 stores layout data for each model. However, the layout data may correspond to a plurality of types of printers. For example, one piece of layout data including both layout data 310 and layout data 330 may be provided. In this case, reference numerals 124 and 144 in FIG. 2 indicating the layout data numbers may be set to the same number. In addition, the server 10 may store only one layout data common to all models existing in the network system 2. This layout data may include all items of printing conditions supported by all types of printers existing in the network system 2. The items (for example, item 214) of the printer information (for example, printer information 210) shown in FIG. 3 include all items of printing conditions that can be currently executed by the printer corresponding to the printer ID included in the printer information and option information ( For example, information including model printing condition information 120 and current printing condition information 218 may be included. Further, the printer information may include information on a data format that can be interpreted by the printer corresponding to the printer ID included in the printer information (for example, interpretable data format information 124). In this case, the server 10 may not store model information as shown in FIG.

  The technical elements described in this specification or the drawings exhibit technical usefulness alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing. In addition, the technology illustrated in the present specification or the drawings achieves a plurality of objects at the same time, and has technical utility by achieving one of the objects.
