  Next, in the present embodiment, a screen displayed on operation panel 407 when setting conditions for a pull print job in MFP 400a will be described.

  FIG. 2 is a diagram showing an example of a pull print job setting screen displayed on the operation panel 407 of the MFP 400a in the first embodiment of the present invention.

  Referring to FIG. 2, when a predetermined operation is accepted on operation panel 407 from the authenticated user, MFP 400 a displays a pull print job setting screen on operation panel 407.

The box BX2 is a combo box that accepts monochrome or color selection.

  FIG. 3 is a diagram showing an example of a file selection screen displayed on the operation panel 407 of the MFP 400a in the first embodiment of the present invention.

  Referring to FIG. 3, when an operation on key KY1 is accepted on the pull print job setting screen, MFP 400a displays a file selection screen.

  The file selection screen includes a message for prompting selection of a file to be printed, keys KY11, KY12, and KY13, and a region RG. The key KY11 is a key for displaying a list of files stored in the storage device 107 of the application server 100. Key KY12 is a key for displaying a list of files stored in storage device 408 of MFP 400a. The key KY13 is a key for displaying a list of files stored in the storage device 202 of the service server 200. The region RG is a region for displaying a list of files stored in the selected storage device.

  FIG. 3 shows a case where the key KY13 is pressed. In this case, the MFP 400a changes the display color of the key KY13, and displays two icons “test1.doc” and “test2.doc” in the region RG as a list of files stored in the storage device 202 of the service server 200. indicate.

  When one of the two icons is operated, the MFP 400a accepts selection of a file corresponding to the icon (here, a file called “test1.doc”) and returns to the pull print job setting screen. In this case, the file name of the selected file (here, “test1.doc”) is displayed on the key KY1 on the pull print job setting screen.

  After that, when the operation of the key KY2 is received, the MFP 400a receives an instruction to execute a pull print job with the file “test1.doc” as a target file.

  The target file may be stored in a location different from that of MFP 400a, and may be stored in storage device 107 of application server 100. When the target file is stored in a predetermined folder in the storage device 107 of the application server 100, the MFP 400a may accept an instruction to execute a pull print job for the target file.

  Next, the operation of the image forming system in the present embodiment will be described.

  FIG. 4 is a flowchart showing the operation of the application server 100 according to the first embodiment of the present invention.

  Referring to FIG. 4, when communication unit 402 of MFP 400 a accepts an operation for displaying a pull print job setting screen (FIG. 2) through operation panel 407 from the user, connection to application server 100 is connected to relay device 300. Request. When the server communication unit 301 of the relay apparatus 300 receives a connection request from the MFP 400a, the server communication unit 301 requests a tunnel connection to the application server 100 through a constant connection.

  When receiving the tunnel connection request from the relay device 300, the communication unit 106 of the application server 100 performs a tunnel connection process (S1). As a result, a tunnel connection, which is a connection for transmitting a print file, is established between the application server 100 and the relay apparatus 300.

  In the tunnel connection process of step S1, the communication unit 106 acquires from the MFP 400a information identifying the MFP 400a, the user ID of the user who has instructed execution of the pull print job, or the job ID that is information identifying the pull print job. It is preferable to do.

  Subsequently, the overall control unit 101 activates a pull print application and causes the MFP 400a to display a pull print job setting screen (S3). Thus, the user of the MFP 400a can select a file and set pull print job conditions. Next, when receiving an instruction to execute a pull print job by the pull print application (S5), the overall control unit 101 determines whether the target file satisfies a predetermined condition (S7).

  The predetermined condition in step S7 is a condition satisfied by a file that requires a long time for conversion. The predetermined condition may include a condition for the capacity of the target file, or may include a condition for the number of pages of the target file. The capacity condition of the target file is, for example, a condition that the target file is larger than a predetermined capacity (for example, 10 MB). The condition of the number of pages of the target file is a condition that the total number of pages of the target file exceeds a predetermined number of pages (for example, 20 pages). The predetermined condition may include both a capacity condition of the target file and a page number condition of the target file. In this case, when the target file satisfies at least one of a condition that the target file exceeds a predetermined capacity and a condition that the target file exceeds a predetermined number of pages, The determination in step S7 is YES.

  The predetermined condition in step S7 may be set to a different value according to the resource usage rate in the MFP 400a, the communication speed between the MFP 400a and the application server 100, and the like.

  If it is determined in step S7 that the predetermined condition is satisfied (YES in S7), it takes time to convert the file. In this case, the overall control unit 101 ends the pull print application (S9). Next, the information storage unit 102 stores information for specifying the MFP 400a that is the transmission source of the pull print job execution instruction in the storage device 107 (S11).

  In step S11, the information storage unit 102 preferably stores, in the storage device 107, information that identifies the MFP 400a, a user ID of a user who has instructed execution of a pull print job, or a job ID.

  Subsequently, the communication unit 106 disconnects the tunnel connection (S13). As a result, the pull print job sequence from the MFP 400a is forcibly canceled (terminated) due to a communication error. The device communication unit 302 of the relay apparatus 300 may notify the MFP 400a of switching from the pull print job to the remote print job when the pull print job is canceled. Next, the overall control unit 101 proceeds to the process of step S15.

  If it is determined in step S7 that the predetermined condition is not satisfied (NO in S7), it does not require time for file conversion. In this case, the overall control unit 101 proceeds to the process of step S15.

  In step S15, the file conversion unit 105 starts a process of converting the format of the target file into a pdf format or the like (S15). The converted file becomes a print file. The file conversion may be started before determining whether the target file satisfies a predetermined condition (S7).

  Next, the overall control unit 101 determines whether or not the pull print application is being activated (S17).

  If it is determined in step S17 that the pull print application is activated (YES in S17), the pull print control unit 103 transmits the converted print file to the MFP 400a (S27), and the process ends. . The MFP 400a performs a print file ripping process as a pull print job, and prints the print file.

  If it is determined in step S17 that the pull print application is not activated (NO in S17), the overall control unit 101 activates the remote print application (S19) and determines whether or not the file conversion is completed (S19). S21). The remote print control unit 104 repeats the process of step S21 until it is determined that the file conversion is completed.

  If it is determined in step S21 that the file conversion has been completed (YES in S21), the remote print control unit 104 specifies the connection destination MFP 400a based on the information specifying the MFP 400a stored in the information storage unit 102. (S23). Subsequently, the communication unit 106 performs tunnel connection processing (S25). As a result, the tunnel connection is established again between the application server 100 and the relay device 300. Next, the remote print control unit 104 generates a remote print job (including PJL (Printer Job Language) and the like). The generated remote print job print condition is preferably set to the same content as the print condition of the canceled pull print job. Next, the remote print control unit 104 transmits the print file together with the remote print job execution instruction through the tunnel connection to the MFP 400a (S27), and ends the process. The MFP 400a performs a ripping process of a print file as a remote print job received from the application server 100, and prints the print file.

  Note that the remote print job transmitted in step S27 is information that associates the canceled pull print job with the transmitted remote print job (for example, information specifying the MFP 400a and the user of the user who issued the pull print job execution instruction). ID etc.). Accordingly, even when the pull print job is switched to the remote print job, the MFP 400a can easily charge the user who has instructed the execution of the pull print job.

  According to the present embodiment, when it takes time to convert the target file of the remote print job received from MFP 400a, the pull print job is switched to the remote job from application server 100. This eliminates the need for the MFP 400a, which is the transmission source of the pull print job execution instruction, to maintain the tunnel connection with the application server 100 until the print file is received. The MFP 400a does not need to continue using resources such as a CPU in order to maintain a tunnel connection with the application server 100. As a result, the processing speed of the MFP 400a can be improved, and communication pressure can be avoided.

  In particular, when the MFP 400a has a gateway function and the relay apparatus 300 is built in the MFP 400a, the relay apparatus 300 operates on the CPU of the MFP 400a, and thus the above-described effect becomes more remarkable.

  [Second Embodiment]
