JP 11-345102 A

  However, in Patent Document 1, one printer driver searches for a printer and outputs to the printer. Normally, printer models that can be supported by the printer driver are limited to printers of a single vendor.

  On the other hand, in this specification, in order to deal with, for example, a plurality of vendors, it is considered to configure in a plug-in format. Accordingly, it is possible to search for a printer using a plurality of plug-ins. On the other hand, when searching for printers using this method, if there are printers that can respond to the search for multiple plug-ins, the same printer is included repeatedly in the detection results of the search for multiple plug-ins. End up. As a result, there is a problem that displaying detection results including duplicate printers is difficult for the user to understand and hesitates to select.

  Therefore, an object of the present invention is to solve the above-described problem by displaying a selection screen by excluding duplicate printers from the detection result.

In order to achieve the above object, an information processing apparatus according to the present invention provides:
Acquisition means for acquiring search detection results from a plurality of plug-ins for searching for a printer;
Display means for displaying a selection screen for selecting the detected printer based on the detection result;
The display means displays the one printer as a single selection candidate on a selection screen when it is determined that one printer is detected in duplicate.

  When one printer is detected in duplicate according to the present invention, it is possible to provide an easy-to-understand and easy-to-select selection screen by displaying a single printer as a single selection candidate.

[Example 1]
First, the configuration of the printing system in this embodiment will be described.

  FIG. 1 shows an example of the overall configuration of a printing system in this embodiment. This system includes a mobile terminal 4000 (corresponding to an information processing apparatus), a printer A8000, and a printer B9000 connected to a network 1000. The network 1000 has various forms such as the Internet and an intranet, but any form may be used as long as each is connected so as to be communicable. Although two printers are taken as an example here, the present invention is not limited to two printers.

  Next, the configuration of the portable terminal 4000 in the embodiment of the present invention will be described with reference to the block diagram of FIG. The mobile terminal 4000 is entirely controlled by a control unit 4050 including a CPU 4051 and a memory 4052. A display unit 4010 indicates an output device such as a display, and an operation unit 4020 indicates an input device using a touch panel or various buttons. A network communication unit 4030 connects to the network 1000 via a 3G line, Wi-Fi, or the like to input / output data to / from an external device. A short-range wireless communication unit 4040 performs short-range wireless communication by NFC (Near Field Communication) to input / output data to / from an external device. The storage unit 4100 stores programs such as various applications (hereinafter referred to as applications) 4110 and an OS 4120. The OS 4120 is software that controls the basic operation of the mobile terminal 4000. The mobile terminal 4000 software configuration and the processing of each step of the flowchart described later are realized by loading a program stored in the storage unit 4100 into the memory 4052 in the control unit 4050 and executing it by the CPU 4051.

  The application 4110 is installed on the portable terminal 4000 and has a function of displaying and printing content such as a photo, a document, and a Web page via the printing system 4130. The printing system 4130 includes a UI unit 4131, a plug-in control unit 4132, a communication unit 4133, a plug-in management unit 4134, and a detection result receiving unit 4135, as shown in FIG. A UI unit 4131 displays a user interface in the printing system 4130. The plug-in control unit 4132 controls the operation of the plug-in installed on the mobile terminal 4000. The communication unit 4133 performs network communication with the printer using a network communication unit 4030 (for example, Wi-Fi). The plug-in management unit 4134 manages information on plug-ins installed on the mobile terminal 4000. The detection result receiving unit 4135 receives a notification of the result of the plug-in detecting the printer on the network. Plug-ins X4140, Y4150, and Z4160 have functions such as searching for a printer, generating a print job, and acquiring a printer status, and transmit information between the printing system 4130 and the target printer. Plug-ins can be installed / uninstalled for each plug-in as needed, and the plug-in management unit 4134 manages the plug-in installation state.

  Here, the plug-in will be described using the plug-in X4140 as an example with reference to FIG. The printer search unit 4141 searches for a printer on the network 1000 using multicast or broadcast. The protocol uses Service Location Protocol (SLP), Multicast-DNS (Domain Name System), etc., but is not limited to this, and may be different for each plug-in. The print processing unit 4142 performs rendering on a PDL (Page Description Language) or an image that can be printed by the printer A 8000 and the printer B 9000.

  FIG. 3 is a screen example of an application 4110 that implements the function of the printing system 4130. When the setting button 4201 is pressed on the screen of the application 4110 on which the content to be printed is displayed, a context menu 4202 is displayed. When the user taps “Print”, the UI unit 4131 of the printing system 4130 is called and a print setting screen 4203 is displayed.

  The print setting screen 4203 includes a target printer display area 4204, a print setting area 4205, and a print button 4206. The user can print the content data of the application 4110 on the printer displayed in the target printer display area 4204 by tapping the print button 4206 after confirming the desired print settings in the print setting area 4205. Here, the printer A8000 of the plug-in X4140 is selected. When changing the output destination to another printer, the target printer display area 4204 is tapped. As a result, a printer selection screen as shown in FIG. 7A is displayed. Hereinafter, an operation until the target printer display area 4204 is tapped and the printer selection screen is displayed will be described.

  FIG. 4 is a flowchart showing an outline of the operation in this embodiment. Here, an example of outputting from the application 4110 to the printer A 8000 is shown. After the application 4110 instructs printing (S101), the printing system 4130 instructs all plug-ins installed in the mobile terminal 4000 to search (S102). The step of S102 is executed when the target printer display area 4204 is tapped on the print setting screen 4203. Next, each plug-in searches for a printer on the network 1000 (S103). In response to the search from each of the plug-ins X4140, Y4150, and Z4160, the printer A 8000 returns a response indicating that printing is possible (S104). Receiving the response from the printer A 8000, each plug-in notifies the printing system 4130 of information on the printer A 8000 as a detection result (S105). The printing system 4130 displays a UI as shown in the printer selection screen of FIG. 7A on the display unit 4010 based on the detection result received from each plug-in (S106).

  FIG. 5 is a flowchart showing an example of detailed operation of the printing system 4130 from when the target printer display area 4204 is tapped on the print setting screen 4203 to when the printer selection screen is displayed. The processing described in the present embodiment is realized by loading a program recorded in the storage unit 4100 into the memory 4052 and executing it by the CPU 4051. First, the target printer display area 4204 is tapped on the print setting screen 4203 (S201). Then, the plug-in control unit 4132 acquires a list of plug-ins already installed in the mobile terminal 4000 via the plug-in management unit 4134 (S202). Next, the plug-in control unit 4132 calls a search process for installed plug-ins (S203).

  FIG. 6 is a flowchart of the search process of the plug-in X4140. In this embodiment, the processing in FIG. 5 and the processing in FIG. 6 are executed asynchronously. When the plug-in search process is called from the plug-in control unit 4132, the printer search unit 4141 transmits a printer search packet by broadcast (S301). After transmitting the search packet, the printer search unit 4141 enters a response reception standby state (S302). Next, it is determined whether the printer search unit 4141 has reached a timeout (S303). If it is determined that the timeout has not been reached, it is determined whether a response from the printer has been received (S304). If it is determined that a response from the printer has been received, the process proceeds to step S305, the detection result is notified to the printing system 4130, and the process returns to step S302. Here, the detection result notified to the printing system 4130 includes the identifier of the detected printer. The printer identifier uniquely identifies a physical printer, and includes an IP address of the printer, for example. After the processes of S302 to S305 are continued until it is determined in step S303 that the timeout has been reached, the search process for the plug-in X4140 is terminated.

  Although an IP address is given as an example of a printer identifier, it is not limited to this. Other printer identifiers include the printer serial number. Alternatively, a MAC address or UUID (Universal Unique ID) may be used. Even when the target printer exists on the cloud, printers having the same printer identifier are displayed together. Furthermore, even if the connection form of the portable terminal and the printer is different, such as IPv4, IPv6, Bluetooth (registered trademark), Wi-Fi Direct, etc., the same individual can be aggregated and displayed to ensure the usability of this patent. . Note that there are other types of plug-ins for multifunction devices such as printing and faxing. The search results for plug-ins with different uses may be displayed separately even if they are the same individual.

  Returning to the processing of the flowchart of FIG. 5, steps after S204 will be described. Subsequently, the plug-in control unit 4132 determines whether or not all plug-in search processes have been called (S204). If all the plug-in search processes have been called, the detection result receiving unit 4135 enters a standby state for receiving a detection result notification from the plug-in (S205).

  Next, it is determined whether or not the detection result receiving unit 4135 has reached a timeout (S206). If it is determined that the timeout has not been reached, the detection result receiving unit 4135 determines whether a notification of the detection result has been received from the plug-in (S207). Specifically, if the detection result receiving unit 4135 has received the result notified by the plug-in in step S305 in the flowchart of FIG. 6, it is determined that the detection result has been received.

  If the detection result receiving unit 4135 has received the notification of the detection result, it refers to the identifier of the printer included in the detection result acquired from the plug-in and determines whether a printer with the same identifier has already been detected ( S208). Thus, it is determined whether or not the printer is detected redundantly based on the detection result. If the printer with that identifier has not been detected yet, the UI detected at this time is displayed on the UI unit 4131 as a single printer (S210). On the other hand, if a printer with the same identifier has already been detected, the printers with the same identifier are collected and displayed on the UI unit 4131 (S209). A method of the aggregate display will be described later with reference to FIG. The printing system 4130 continues the processes in S205 to S210 until it is determined in step S206 that the timeout has been reached, and then ends the printer selection screen display process.

  Next, a method in which the printing system 4130 collectively displays printers having the same identifier on the UI unit 4131 will be described with some examples.

  FIG. 7 shows the appearance of the printer selection screen in the first embodiment.

  In the present embodiment, as shown in FIG. 4, all of the plug-in X4140, plug-in Y4150, and plug-in Z4160 can print to the printer A8000. Even in such a case, in FIG. 7A, the printer A is displayed only in 4301 for display. This is a result of the printing system 4130 collecting and displaying the printers having the same identifier in step S209 in FIG. To display in a consolidated manner, for duplicate printers, specify one plug-in based on the priority and default settings described later, and display the printer selection screen except for plug-ins other than the specified plug-in. That is. In the example of FIG. 7A, the printer selection screen is displayed for the redundantly detected printer A8000 except for the detection results of the plug-in Y4150 and the plug-in Z4160 other than the plug-in X4140. Thus, only the detection result of the plug-in X4140 is displayed as a single selection candidate for the printer A8000 on the printer selection screen.

  On the other hand, the plug-in that can print to the printer B is only the plug-in Y4150. Therefore, only the single 4304 is displayed to display the printer B. This is a result of the printing system 4130 displaying as a single printer in step S210 of FIG. In 4304, a plus (+) mark 4310 described later is not displayed on the left side. Since the plus mark 4310 is not displayed, the user can grasp that there is only a plug-in Y4150 that can be printed with respect to the printer B, unlike the case of the printer A.

  If the printing system 4130 displays all the printers received by the detection result receiving unit 4135 uniformly on the UI unit 4131, the printer selection screen is as shown in FIG. A plurality of printers such as 4401, 4402, and 4403 are displayed for each plug-in for the physically same printer A, and usability is very poor. Although only two printers, printer A8000 and printer B9000, are connected on the network 1000 of this embodiment as shown in FIG. 1, a total of four printers are displayed on the printer selection screen. become.

  On the other hand, usability at the time of printer selection can be improved by displaying the printer selection screen shown in FIG. Specifically, in the example of FIG. 7A, the printer A8000 is integrated into the plug-in X4140. When the user taps 4301, the printer A8000 using the plug-in X4140 is selected, and the output destination of the application 4110 is the plug-in. The printer A 8000 using X4140 is set, and the screen returns to the screen of FIG. In the target printer display area 4204 of the print setting screen 4203 in FIG. 3B, the printer A 8000 of the plug-in X4140 is displayed. That is, the display as shown in FIG. 7A reduces the choices on the printer selection screen, and the user can easily select the printer.

  Here, a method for returning to the printer selection screen of FIG. In this embodiment, a plus mark 4310 is displayed on the left side of the printer that has performed the aggregate display on the printer selection screen. The plus mark 4310 functions as a reception unit that receives an instruction to display a plug-in other than the specified plug-in, which is removed from the printer selection screen in FIG. 7A, together with the specified plug-in.

  Specifically, when the plus mark 4310 is tapped by the user, the printing system 4130 changes the plus mark 4310 to a minus (−) mark 4311 as shown in FIG. Is released. In FIG. 7B, plug-in Y and plug-in Z that can be printed on the printer A 8000 are also displayed as plug-in options (4302, 4303) that can be used. In FIG. 7B, a line 4312 is drawn below the minus mark 4311 so that the plug-in Y and the plug-in Z can be printed on the printer A 8000 similarly to the plug-in X.

  As described above, the plus mark 4310 is displayed only on the printers displayed in an integrated manner on the printer selection screen of FIG. As a result, on the printer selection screen in FIG. 7A, the printers displayed in an aggregated manner in S209 in FIG. 5 and the printers displayed solely in S210 are displayed in an identifiable manner.

  When 4303 is tapped by the user in FIG. 7B, the printing system 4130 returns to the screen of FIG. 3B and displays the printer A 8000 of the plug-in Z 4160 in the target printer display area 4204. When the minus mark 4311 is tapped in FIG. 7B, the screen returns to the screen of FIG.

  According to the present embodiment, even if one printer is detected by a plurality of plug-ins, one printer can be displayed on the selection screen as a single selection candidate.

[Example 2]
FIG. 8 shows the appearance of the printer selection screen in the second embodiment. Since the printing system 4130 collects and displays the printers having the same identifier as in the first embodiment, 4401 of the printer A using the plug-in X4140 and 4404 of the printer B using the plug-in Y4150 are displayed on the printer selection screen. ing. Further, in this embodiment, a cancel button 4410 is displayed, which indicates that “printers overlapping the above two printers are excluded. Tap here to display all search results”. The cancel button 4410 is a button for canceling the aggregate display, and when the user taps the cancel button 4410, the display of FIG. That is, 4401 of the printer A using the plug-in X4140 is expanded into three buttons 4401 to 4403. The cancel button 4410 is not displayed on the screen after canceling the aggregate display. Also in this embodiment, when the user taps 4403 as in the first embodiment, the printing system 4130 returns to the screen of FIG. At that time, the printer A8000 of the plug-in Z4160 is displayed in the target printer display area 4204.

[Example 3]
FIG. 9 shows the appearance of the printer selection screen in the third embodiment. In this case as well, the printing system 4130 collects and displays the printers having the same identifier as in the previous embodiment. Therefore, the printer selection screen displays 4501 of printer A using plug-in X4140 and 4504 of printer B using plug-in Y4150. Further, in this embodiment, a character string 4511 “Use other plug-in” is displayed in the display area 4501. Reference numeral 4511 denotes a link for canceling the aggregate display, and when the user taps 4511, the display of FIG. 9B is performed. That is, 4501 of the printer A using the plug-in X4140 is expanded to buttons 4501 to 4503. A string 4511 for canceling aggregation is not displayed in 4501 after canceling the aggregation display. Also in this embodiment, the operation when 4503 is tapped by the user is the same as that of the above-described embodiment.

  The printer integrated display in this patent has been described above using the first to third embodiments. When collecting and displaying printers with the same identifier in step S209, the problem is which plug-in to collect and display. Here, a method for assigning priorities to all plug-ins installed in the mobile terminal 4000 will be described. The plug-in management unit 4134 gives priority to all installed plug-ins. The priority order can be changed by the user, and the UI unit 4131 displays a setting screen for changing the priority order.

  The display shown in FIG. 10A is a priority setting change screen. FIG. 10A is a screen that can be opened from the setting screen of the OS 4120 of the mobile terminal 4000, and indicates that the plug-in displayed at the top of the screen has a higher priority. The user can move the desired plug-in higher or lower by tapping and dragging the plug-in displayed in Fig. 10 (a) to any place to change the existing priority. Can do.

  Based on the priority order designated by the user, the plug-in management unit 4134 determines in which plug-in printers with the same identifier are collected in step S209 in FIG. Therefore, when the plug-in X4140 is set to the first priority as shown in FIG. 10A, the plug-in X4140 is collected in step S209. In addition, the order after the second priority order is reflected in the order of arrangement when the aggregation is canceled as shown in FIG.

  Note that when installing a new plug-in, the plug-in management unit 4134 may register the plug-in with the highest priority. In this way, even if a plurality of printers are found by searching, they can be displayed collectively as the most recently installed plug-in printer.

  Further, as shown in FIG. 10B, only one default plug-in may be set. The behavior of the printer selection screen when the default plug-in is set is the same as when the plug-in is set to the first priority in FIG. 10A.

  The priority order of all plug-ins installed in the portable terminal 4000 is also valid at the time of touch printing. In touch printing, an NFC tag storing an IP address in advance is attached to the printer. When the portable terminal 4000 is touched on the NFC tag, the short-range wireless communication unit 4040 of the portable terminal 4000 detects it, and acquires the IP address of the printer from the NFC tag. The printing system 4130 acquires a touch print event via the OS 4120. The printing system 4130 then requests a printer search based on the acquired IP address for each installed plug-in. When the print system 4130 receives notification of detection results from a plurality of plug-ins, the print system 4130 refers to the priority order described above and instructs the plug-in with the highest priority to print. This enables printing using a plug-in with a high priority without performing UI display during touch printing.
