  [Overview of image forming system operation]

  First, an outline of the operation of the image forming system in the present embodiment will be described.

  FIG. 1 is a diagram for explaining the outline of the operation of the image forming system according to the embodiment of the present invention.

  Referring to FIG. 1, the image forming system in the present embodiment includes a terminal device 100, an MFP 200 (an example of an image forming device), and a server 300. Each of terminal apparatus 100, MFP 200, and server 300 is connected to each other through network 400.

  The network 400 uses a dedicated line such as a wired or wireless LAN (Local Area Network). The network 400 connects various devices using a TCP / IP (Transmission Control Protocol / Internet Protocol) protocol. Devices connected to the network 400 can exchange various data with each other.

  The terminal device 100 is a terminal device possessed by the user UR, and is wirelessly connected to a base station 401 connected to the network 400. The terminal device 100 performs narrow-band communication with each of the MFP 200 and the server 300. Each of MFP 200 and server 300 is wired to network 400. The MFP 200 performs broadband communication with the server 300. Note that the terminal device 100 may be wired to the network 400, and each of the MFP 200 and the server 300 may be wirelessly connected to the network 400.

  Note that the terminal device 100, the MFP 200, and the server 300 may be connected to each other via an external device (not shown) such as another terminal device, MFP, or server via the network 400.

  The terminal device 100 stores files DC11, DC12, and DC13 that are document files, for example. The terminal device 100 is installed with an application (application) for editing a file and storage service software (synchronization software).

  The server 300 stores files DC21, DC22, and DC23. The file DC21 corresponds to the file DC11, the file DC22 corresponds to the file DC12, and the file DC23 corresponds to the file DC13.

  Storage service software is installed in the terminal device 100, and the terminal device 100 can use an online storage service provided by the server 300. The terminal device 100 is periodically (at regular time intervals) with the server 300 for the purpose of backing up files (data) created in the terminal device 100 and for use in other terminal devices. (Or at a fixed time) or when an instruction is received from the user UR. Specifically, the terminal device 100 and the server 300 execute a synchronization process for synchronizing each of the files DC21, DC22, and DC23 with each of the files DC11, DC12, and DC13. The synchronization process is indicated by an arrow AR1.

  The synchronization process means a process of updating the file stored in the server so that the content of the file stored in the server matches the content of the file stored in the terminal device. The timing at which the synchronization process is performed is arbitrary.

  At the terminal 100, the user UR edits the file DC11 (or file DC21) stored in the terminal device 100, and issues a print instruction for the edited file DC11 (or edited file DC21). When the storage service software installed in the terminal device 100 accepts the print instruction, the storage service software designates the file DC11 or the file DC21 stored in the server 300 and issues a print instruction (this designation is only temporary and is actually The file to be printed is determined in the process described later). When the terminal device 100 receives a print instruction from the user UR, the terminal device 100 executes print processing for transmitting a print execution instruction regarding the file DC11 or DC21 to the MFP 200. The printing process is indicated by an arrow AR2. Upon receiving the print instruction, the MFP 100 receives a file to be printed from the terminal device 100 or the server 200, executes printing, and outputs a file DC31.

  The terminal device 100 acquires information on the state of the terminal device 100, information on the communication state between the MFP 200 and the server 300, and information on the state of the MFP 200 when it is necessary to simultaneously execute the printing process and the synchronization process ( Monitoring). Further, the terminal device 100 acquires information on the file specified by the storage service software. Further, when the file specified by the storage service software is the file DC11, the terminal device 100 further acquires information on whether or not the file DC21 has been synchronized with the file DC11. Then, the terminal device 100 determines which of the printing process and the synchronization process is to be executed with priority based on the acquired information.

  In a predetermined case, the terminal device 100 determines a file different from the file specified by the storage service software as a print target, and transmits a print execution instruction related to the file.

  The terminal device 100 acquires information on at least one of the state of the terminal device 100, the communication state between the MFP 200 and the server 300, and the state of the MFP 200, and print processing and synchronization processing are performed based on the acquired information. Any of these may be determined as long as priority is given to execution.

  [Configuration of image forming system]

The print instruction unit 115 executes print processing for transmitting to the MFP 200 a print execution instruction related to the file stored in the storage unit 130 or the file stored in the server 300 in accordance with the print instruction from the user. The state detection unit 117 acquires (detects) information on the state of the terminal device 100. Here, as an example of information on the state of the terminal device 100, information on whether or not the terminal device 100 is in a state where communication can be continued stably is acquired.

  [Operation of image forming system when it is necessary to start print processing during execution of synchronization processing]

  Next, the operation of the image forming system when it becomes necessary to start the printing process during the execution of the synchronization process will be described.

  FIG. 3 is a first half of a sequence diagram for explaining the operation of the image forming system when it is necessary to start the printing process during the execution of the synchronization process in the embodiment of the present invention.

  With reference to FIG. 3, the terminal device 100 and the server 300 start the synchronization process at the timing set by the storage service software or the like. The storage service software of the terminal device 100 transmits a synchronization start command to the server 300. When receiving the synchronization start command, the server 300 transmits file information necessary for the synchronization processing to the terminal device 100. Specifically, the server 300 transmits information such as the version (update date and time) of each of the files DC21, DC22, and DC23. As a result, the terminal device 100 and the server 300 start the synchronization process.

  During the synchronization process, the terminal device 100 and the server 300 perform, for example, the following communication. The terminal device 100 compares the received versions of the files DC21, DC22, and DC23 with the versions of the files DC11, DC12, and DC13 stored in the terminal device 100. Then, the terminal device 100 transmits the files DC11, DC12, and DC13 that have a newer version (the files DC21, DC22, and DC23 have different versions) to the server 300 in order. The server 300 overwrites the received file (for example, the file DC11) on the file (for example, the file DC21) corresponding to the received file, and notifies the terminal device 100 of the completion of the storage. When the terminal device 100 receives the notification of the completion of storage, the terminal device 100 transmits the file to the server 300 when there is a file that needs to be transmitted, and performs synchronization processing when there is no file that needs to be transmitted. The server 300 is notified of the end.

  During the execution of the synchronization process, the user UR sets the contents of the print job, and then issues a print instruction through an application such as PageScope Workware (registered trademark). As a result, the terminal device 100 needs to start the printing process during the execution of the synchronization process.

  Upon receiving the print instruction, the terminal device 100 requests the MFP 200 to transmit information while continuing (without interrupting) the synchronization processing being executed. When receiving a request from the terminal device 100, the MFP 200 detects whether the MFP 100 itself is busy, idle, or suspended (performs MFP status check). Busy is a state in which the MFP 200 is performing an image forming operation. The idle is a state in which printing can be started immediately if the MFP 200 is not performing an image forming operation and image data is received. Suspend is a state in which the MFP 100 is not performing an image forming operation and a part of the power supply in the MFP 100 is turned off. Further, the MFP 200 detects the communication state between the MFP 100 and the server 300 by performing transmission / reception of test data to / from the server 300 (performs a response check). The MFP 200 transmits the detected information to the terminal device 100. The terminal device 100 acquires information transmitted from the MFP 200.

  Further, when receiving the print instruction, the terminal device 100 acquires information on the state of the terminal device 100 itself (performs a terminal status check) while continuing the synchronization processing being executed. The terminal device 100 includes, as information on the state of the terminal device 100, information on the remaining battery level of the terminal device 100, information on radio wave status of wireless communication (WiFi (Wireless Fidelity) or 3G) of the terminal device 100, and the terminal device 100. CPU usage rate information is acquired.

  Further, when receiving the print instruction, the terminal device 100 acquires the information on the file (file DC11 or DC21) specified by the storage service software while continuing the synchronization processing being executed. When the designated file is the file DC11, the terminal device 100 determines whether or not the synchronization processing between the files DC11 and DC21 has been completed (whether the contents of the file DC21 are the same as the contents of the file DC11). Get more information.

  When the terminal apparatus 100 acquires the above-described information, the terminal apparatus 100 determines a process to be preferentially executed among the printing process and the synchronization process based on the acquired information. In addition, the terminal device 100 determines whether the file to be printed is the file DC11 (whether to perform push printing from the terminal device 100) or the file DC21 (pull from the server 300) based on the acquired information. To print). These determinations are made using, for example, operation tables as shown in FIGS.

  4 and 5 are diagrams schematically showing an operation table in the case where it is necessary to start the printing process during the execution of the synchronization process in the embodiment of the present invention. Here, one operation table in which the state of the image forming system is classified into cases A1 to A18 is divided into two diagrams.

  As is apparent from the operation table shown below, in this embodiment, the print target is set to the synchronized file DC21 stored in the server as much as possible (pull print from the server as much as possible). Thus, a file to be printed is transmitted to the MFP in a short time through broadband communication between the MFP and the server.

  Referring to FIG. 4, this operation table describes the relationship between the state of the image forming system, processing executed preferentially among printing processing and synchronization processing, and control performed by the terminal device. The state of the image forming system is defined by the type of monitoring and the designation destination of the print file (file designated by the storage service software).

  The types of monitoring include the status of the terminal device (the battery level of the terminal device, the radio wave status of wireless communication, and the usage rate of the CPU of the terminal device), the status of the MFP, and the communication status between the MFP and the server (traffic, transfer) Speed). The remaining battery level of the terminal device is divided into two types: “Low” (a state where the remaining battery level is low) and “Not Low” (a state where the remaining battery level is sufficient). The radio wave conditions of the wireless communication of the terminal device are classified into two types, “strong” and “weak”. The CPU usage rate of the terminal device is divided into two types: “Idle” (a low CPU usage rate) and “Busy” (a high CPU usage rate). The state of the MFP is divided into three types: busy, idle, and suspend. The communication state between the MFP and the server is classified into two types, “Normal” (a state where the communication speed is equal to or higher than the reference value) and “Low” (a state where the communication speed is lower than the reference value).

  The designation destination of the print file is divided into a server (file DC21) and a terminal device (file DC11). Further, in the case where the specified destination of the print file is the terminal device and the synchronization processing between the file DC11 and the file DC21 is completed in the interrupted synchronization processing (the contents of the file DC11 and the contents of the file DC21) Are marked with a circle in the “Server” field.

  In this operation table, when the state of the image forming system is cases A9, A16, A17, and A18, it is specified that priority is given to the synchronization processing, and the states of the image forming system are cases A1 to A8 and A10. In the case of A15, priority is given to print processing. Hereinafter, the operation of the image forming system in each case defined in the operation table will be described.

  In cases A1 to A3, there is a problem in the state of the terminal device (not the state in which the terminal device can stably continue communication), the MFP state and the communication state between the MFP and the server are normal, and the print file In this case, the designated destination is the server (file DC21). In cases A1 to A3, since the MFP can immediately execute printing, the terminal device prioritizes printing processing. In addition, as a printing process, the terminal device transmits an execution instruction for printing the content to be pulled from the server (the print target is the file DC21) to the MFP. Since there is a problem with the state of the terminal device, the terminal device does not resume the synchronization process after the printing process is completed.

  In cases A4 and A5, there is a problem in the state of the MFP or the communication state between the MFP and the server (the MFP cannot execute printing immediately, or the communication state between the MFP and the server is not good), and the state of the terminal device Is normal, and the designation of the print file is the server (file DC21). In cases A4 and A5, since the MFP can execute printing without delay (within a certain amount of time), the terminal device gives priority to the printing process. In addition, as a printing process, the terminal device transmits an execution instruction for printing the content to be pulled from the server (the print target is the file DC21) to the MFP. Since there is no problem in the state of the terminal device, the terminal device resumes the synchronization process after the printing process is completed.

  In cases A6 to A8, there is a problem in the state of the terminal device, the state of the MFP and the communication state between the MFP and the server are normal, the designation destination of the print file is the terminal device (file DC11), and the file DC11 And the synchronization of the file DC21 is not completed. In cases A6 to A8, since the MFP can immediately execute printing, the terminal device prioritizes printing processing. In addition, as a printing process, the terminal device transmits a print execution instruction for the content to be subjected to push printing from the terminal device (the print target is the file DC11) and the file DC11 to the MFP. Since there is a problem with the state of the terminal device, the terminal device does not resume the synchronization process after the printing process is completed.

  In case A9, there is a problem in the state of the MFP, the state of the terminal device and the communication state between the MFP and the server are normal, the designation destination of the print file is the terminal device (file DC11), and the file DC11 and the file This is a case where the synchronization of the DC 21 is not completed. In case A9, since the MFP cannot execute printing without delay, the terminal device gives priority to the synchronization processing. In the synchronization process in this case, the terminal device executes the synchronization between the file DC11 and the file DC21 with priority over the synchronization of other files. Then, after the synchronization between the file DC11 and the file DC21 is completed, and before the synchronization processing is completed, the terminal device executes a print execution instruction (contents to be printed) from the server in parallel with the synchronization processing. Is executed to the file DC21, and is transmitted to the MFP.

  In case A10, there is a problem in the communication state between the MFP and the server, the state of the terminal device and the state of the MFP are normal, the designation destination of the print file is the terminal device (file DC11), and the file DC11 and the file This is a case where the synchronization of the DC 21 is not completed. In case A10, since the MFP can execute printing without delay, the terminal device gives priority to the printing process. In addition, as a printing process, the terminal device transmits a print execution instruction for the content to be subjected to push printing from the terminal device (the print target is the file DC11) and the file DC11 to the MFP. Since there is no problem in the state of the terminal device, the terminal device resumes the synchronization process after the printing process is completed.

  Referring to FIG. 5, in cases A11 to A13, there is a problem in the state of the terminal device, the MFP state and the communication state between the MFP and the server are normal, and the designation destination of the print file is the terminal device (file DC11). ) And the synchronization of the file DC11 and the file DC21 is completed. In cases A11 to A13, since the MFP can immediately execute printing, the terminal device prioritizes printing processing. Also, the terminal device transmits to the MFP a print execution instruction (print execution instruction for changing the print target to the file DC21) from the server in order to shorten the file transmission time. Since there is a problem with the state of the terminal device, the terminal device does not resume the synchronization process after the printing process is completed.

  Case A14 has a problem with the state of the MFP, the state of the terminal device and the communication state between the MFP and the server are normal, the designation destination of the print file is the terminal device (file DC11), and the file DC11 and the file This is a case where the synchronization of the DC 21 is completed. In Case A14, since the MFP can execute printing without delay, the terminal device gives priority to the printing process. Further, the terminal device transmits a print execution instruction (print execution instruction in which the print target is changed to the file DC21) to the MFP in order to shorten the file transmission time from the server. Since there is no problem in the state of the terminal device, the terminal device resumes the synchronization process after the printing process is completed.

  In case A15, there is a problem in the communication state between the MFP and the server, the state of the terminal device and the state of the MFP are normal, the designation destination of the print file is the terminal device (file DC11), and the file DC11 and the file This is a case where the synchronization of the DC 21 is completed. In case A15, since the MFP can execute printing without delay, the terminal device gives priority to the printing process. In consideration of the problem with the communication state between the MFP and the server, the terminal device also performs push printing from the terminal device (the print target is the file DC11), and an instruction to execute printing of the contents , And the file DC11 are transmitted to the MFP. Since there is no problem in the state of the terminal device, the terminal device resumes the synchronization process after the printing process is completed.

  Cases A16 to A18 are cases where the state of the terminal device, the state of the MFP, and the communication state between the MFP and the server are all normal. Each of the cases A11 to A13 is different from each other only in the designation of the print file or whether or not the synchronization of the file DC11 and the file DC21 is completed. In cases A16 to A18, since the synchronization process is predicted to be completed in a short time, priority is given to the synchronization process (the process performed earlier). Then, after the synchronization processing is completed, the terminal device transmits a print execution instruction for performing the pull print from the server to the MFP.

  In cases A16 to A18, as in case A9, the terminal device executes synchronization between the file DC11 and the file DC21 in preference to synchronization with other files, and the synchronization between the file DC11 and the file DC21 is performed. At the time of completion, in parallel with the synchronization processing, a print execution instruction (print execution instruction with the print target as the file DC21) for content to be pulled from the server may be transmitted to the MFP.

  In the above-described operation table, it is described that when there is a problem in the state of the terminal device, the terminal device performs control not to resume the synchronization process. However, the terminal device is synchronized even when there is a problem in the state of the terminal device. Processing may be resumed.

  FIG. 6 is a second half of a sequence diagram for explaining the operation of the image forming system when it is necessary to start the printing process during the execution of the synchronization process in the embodiment of the present invention. FIG. 6 illustrates the operation of the image forming system when the state of the image forming system is case A10.

  Referring to FIG. 6, when the state of the image forming system is case A10, the communication state is poor (transfer is slow) even though broadband communication is possible between MFP 200 and server 300. In this state, if the pull processing from the server 300 is performed after giving priority to the synchronization processing between the file DC11 and the file DC21, the printing efficiency is poor and the printing is delayed and the user UR waits unnecessarily. There is a risk of being.

  Therefore, the terminal device 100 determines to give priority to the printing process. The terminal device 100 interrupts the synchronization processing, and transmits to the MFP 200 the print execution instruction of the content to be subjected to push printing from the terminal device 100 (the print target is the file DC11) and the file DC11 as the print processing.

  The MFP 200 starts receiving the information transmitted by the terminal device 100. When the reception is completed, the MFP 200 executes printing based on the received information and notifies the terminal device 100 that the reception is completed. When the terminal device 100 receives from the MFP 200 a notification that reception has been completed, the terminal device 100 resumes the interrupted synchronization process.

  Thus, by determining the priority process from the result of detecting each state, the print process can be executed quickly and the synchronization process is not interrupted unnecessarily.

  7 to 9 are flowcharts showing the operation of the terminal device when it becomes necessary to start the printing process during the execution of the synchronization process in the embodiment of the present invention.

  With reference to FIG. 7, the control part of a terminal device starts a synchronization process (S1). When the control unit of the terminal device accepts a print instruction after print settings are made by the user (S3), the terminal device state, the MFP state, and the communication state between the MFP and the server (network state) And information on the file designated by the storage service software is acquired (S5). Next, the control unit of the terminal device determines which one of the file stored in the terminal device and the file stored in the server is designated by the storage service software (S7).

  If it is determined in step S15 that the synchronization has been completed (Yes in S15), the control unit of the terminal device proceeds to the process of step S31 in FIG.

  Referring to FIG. 8, in step S21, the control unit of the terminal device determines whether or not the MFP can immediately execute printing (the MFP is in a normal state) (S21).

  If it is determined in step S21 that the MFP is not ready to execute printing (No in S21), the control unit of the terminal device prioritizes synchronization processing and prioritizes synchronization of files to be printed. Then, after the synchronization of the file to be printed is completed, a print execution instruction of the content to be pulled from the server is transmitted to the MFP (S23). Thereafter, the control unit of the terminal device ends the process.

  If it is determined in step S21 that the MFP is ready to execute printing (Yes in S21), the control unit of the terminal device determines whether the communication state between the MFP and the server is good (normal). It discriminate | determines (S25).

An instruction is transmitted to the MFP (S27). After the printing process is completed, the control unit of the terminal device resumes the synchronization process (S28) and ends the process.

  If it is determined in step S25 that the communication state between the MFP and the server is good (Yes in S25), the control unit of the terminal device gives priority to the synchronization processing, and after the synchronization processing is completed, pull-printing from the server is performed.

Is transmitted to the MFP (S33). After the printing process is completed, the control unit of the terminal device ends the process without restarting the synchronization process (S34).

  If it is determined in step S31 that the state of the terminal apparatus is stable (Yes in S31), the control unit of the terminal apparatus is in a state where the MFP can immediately execute printing (the MFP state is normal). Whether or not) is determined (S35).

An instruction to execute printing of the content to be performed is transmitted to the MFP (S43). Thereafter, the control unit of the terminal device ends the process.

  [Operation of image forming system when it is necessary to start synchronous processing during printing processing]

  Next, the operation of the image forming system when it is necessary to start the synchronization process during the printing process will be described.

  FIG. 10 is a first half of a sequence diagram for explaining the operation of the image forming system when it is necessary to start the synchronization process during the execution of the printing process in the embodiment of the present invention.

  Referring to FIG. 10, after setting the contents of the print job, user UR issues a print instruction for file DC11 (file DC21 stored in server 300 may be designated).

  Upon receiving the print instruction, the terminal apparatus 100 transmits, as print processing, an instruction to execute push printing from the terminal apparatus 100 (the print target is the file DC11) and a file DC11 to the MFP.

  Since the data amount of the file DC11 is larger than the data amount of the print execution instruction, particularly in the case of push printing from the terminal device 100, the printing process takes time. Even in the case of pull printing from the server 300, the printing process may take time when there is a problem in the state of the terminal device 100, the state of the MFP, or the communication state between the MFP and the server. Here, it is assumed that the synchronization processing is started in a state where time is required for the printing processing due to these factors.

  The terminal device 100 detects that the scheduled start time of the synchronization process has been reached during the printing process. As a result, the terminal device 100 needs to start the synchronization process during the printing process.

  When the terminal apparatus 100 detects that the scheduled start time of the synchronization process has been reached during the printing process, the terminal apparatus 100 interrupts the printing process and requests the MFP 200 to transmit information. When receiving a request from the terminal device 100, the MFP 200 detects whether the MFP 100 itself is busy, idle, or suspended (performs MFP status check). Further, the MFP 200 detects the communication state between the MFP 100 and the server 300 by performing transmission / reception of test data to / from the server 300 (performs a response check). The MFP 200 transmits the detected information to the terminal device 100. The terminal device 100 acquires information transmitted from the MFP 200.

  Further, when the terminal device 100 detects that the scheduled start time of the synchronization processing has been reached during the printing process, the terminal device 100 interrupts the printing process and acquires information on the state of the terminal device 100 itself (performs a terminal status check).

  Further, when the terminal apparatus 100 detects that the scheduled start time of the synchronization process has been reached during the printing process, the terminal apparatus 100 interrupts the printing process and acquires information on the file (file DC11 or DC21) designated by the storage service software. When the designated file is the file DC11, the terminal device 100 determines whether or not the synchronization processing between the files DC11 and DC21 has been completed (whether the contents of the file DC21 are the same as the contents of the file DC11). Get more information.

  When the terminal apparatus 100 acquires the above-described information, the terminal apparatus 100 determines a process to be preferentially executed among the printing process and the synchronization process based on the acquired information. In addition, the terminal device 100 determines whether the file to be printed is the file DC11 (whether to perform push printing from the terminal device 100) or the file DC21 (pull from the server 300) based on the acquired information. To print). These determinations are made using, for example, an operation table as shown in FIG.

  FIG. 11 is a diagram schematically showing an operation table in the case where it is necessary to start the synchronization process during the execution of the printing process in the embodiment of the present invention.

  Referring to FIG. 11, in this operation table, when the state of the image forming system is case B9, priority is given to the synchronization processing. The states of the image forming system are cases B1 to B8 and B10. In some cases, priority is given to print processing. Hereinafter, the operation of the image forming system in each case defined in the operation table will be described.

  Cases B1 to B3 are cases in which there is a problem in the state of the terminal device, the MFP state and the communication state between the MFP and the server are normal, and the print file designation destination is the server (file DC21). In cases B1 to B3, since the MFP can immediately execute printing, the terminal device prioritizes (resumes) the printing process. In addition, as a printing process, the terminal device transmits an execution instruction for printing the content to be pulled from the server (the print target is the file DC21) to the MFP. Since there is a problem with the state of the terminal device, the terminal device does not execute the synchronization process even after the printing process is completed.

  Cases B4 and B5 are cases in which there is a problem in the state of the MFP or the communication state between the MFP and the server, the state of the terminal device is normal, and the print file designation destination is the server (file DC21). In cases B4 and B5, since the MFP can execute printing without delay (within a certain amount of time), the terminal device prioritizes (resumes) the printing process. In addition, as a printing process, the terminal device transmits an execution instruction for printing the content to be pulled from the server (the print target is the file DC21) to the MFP. Since there is no problem in the state of the terminal device, the terminal device executes the synchronization process after the printing process is completed.

  In cases B6 to B8, there is a problem in the state of the terminal device, the state of the MFP and the communication state between the MFP and the server are normal, and the designation destination of the print file is the terminal device (file DC11). In cases B6 to B8, since the MFP can immediately execute printing, the terminal device prioritizes (resumes) the printing process. In addition, as a printing process, the terminal device transmits a print execution instruction for the content to be subjected to push printing from the terminal device (the print target is the file DC11) and the file DC11 to the MFP. Since there is a problem with the state of the terminal device, the terminal device does not execute the synchronization process even after the printing process is completed.

  Case B9 is a case where there is a problem in the state of the MFP, the state of the terminal device and the communication state between the MFP and the server are normal, and the designation destination of the print file is the terminal device (file DC11). In case B9, since the MFP cannot execute printing without delay, the terminal device gives priority to the synchronization processing. In the synchronization process in this case, the terminal device executes the synchronization between the file DC11 and the file DC21 with priority over the synchronization of other files. When the synchronization between the file DC11 and the file DC21 is completed, the terminal device executes a print execution instruction for the content to be pulled from the server in parallel with the synchronization process (printing with the print target changed to the file DC21). Execution instruction) is transmitted to the MFP.

  In the synchronization process in case B9, the terminal apparatus determines the priority of synchronization between the file DC11 and the file DC21 so that printing can be performed immediately when the MFP can immediately perform printing. It may be.

  Case B10 is a case where there is a problem in the communication state between the MFP and the server, the state of the terminal device and the state of the MFP are normal, and the designation destination of the print file is the terminal device (file DC11). In case B10, since the MFP can execute printing without delay, the terminal device prioritizes (resumes) the printing process. In addition, as a printing process, the terminal device transmits a print execution instruction for the content to be subjected to push printing from the terminal device (the print target is the file DC11) and the file DC11 to the MFP. Since there is no problem in the state of the terminal device, the terminal device executes the synchronization process after the printing process is completed.

  Case B11 is a case where the state of the terminal device, the state of the MFP, and the communication state between the MFP and the server are all normal. In case B11, since the MFP can execute printing without delay, priority is given to (resuming) the printing process (the process that was performed first). In addition, as a printing process, the terminal device transmits a print execution instruction for the content to be subjected to push printing from the terminal device (the print target is the file DC11) and the file DC11 to the MFP. Since there is no problem in the state of the terminal device, the terminal device executes the synchronization process after the printing process is completed.

  In the above-described operation table, it is described that when there is a problem in the state of the terminal device, the terminal device performs control not to resume the synchronization process. However, the terminal device is synchronized even when there is a problem in the state of the terminal device. Processing may be resumed.

  FIG. 12 is the second half of a sequence diagram for explaining the operation of the image forming system when it is necessary to start the synchronization process during the execution of the printing process in the embodiment of the present invention. FIG. 12 illustrates the operation of the image forming system when the state of the image forming system is case B9.

  Referring to FIG. 12, when the state of the image forming system is case B9, MFP 200 cannot immediately execute printing even though broadband communication is possible between MFP 200 and server 300. In this state, even if priority is given to the printing process, the MFP 200 cannot immediately execute printing, and the user UR may wait unnecessarily. That is, in this state, it is efficient to transfer the print file to the MFP 200 via the server 300 with priority given to the synchronization processing.

  Therefore, the terminal device 100 determines to give priority to the synchronization processing. The terminal device 100 starts synchronization processing with the server, and transmits to the server 300 a command for raising the priority of synchronization between the file DC11 and the file DC21 (print file synchronization). Upon receiving this command, the server 300 increases the priority of print file synchronization, and when the print file synchronization is completed, the server 300 notifies the terminal device 100 of the completion of the print file synchronization. Upon receiving the notification of completion of print file synchronization, the terminal device 100 performs pull printing from the server 300 (printing target is the file DC21) as print processing in parallel with the synchronization processing. An instruction is transmitted to the MFP. The MFP 200 receives the execution instruction. Note that the state of the MFP 200 usually changes from a problem state (busy or suspend) to a normal state (idle) before receiving an execution instruction.

  When the MFP 200 receives the execution instruction, the MFP 200 requests the server 300 to transmit (transfer) the print file (file DC21). When the MFP 200 receives a print file from the server 300, the MFP 200 executes printing.

  Thus, by determining the priority process from the result of detecting each state, the print process can be executed quickly.

  FIG. 13 and FIG. 14 are flowcharts showing the operation of the terminal device when it is necessary to start the synchronization process during the execution of the printing process in one embodiment of the present invention.

  Referring to FIG. 13, the control unit of the terminal device starts a printing process (S101). When the control unit of the terminal apparatus detects that the scheduled start time of the synchronization process has been reached during the printing process (S103), the printing process is interrupted (S104), the terminal apparatus state, the MFP state, and the MFP The communication state (network state) between the server and the server is detected, and the file information designated by the storage service software is acquired (S105). Next, the control unit of the terminal device determines which one of the file stored in the terminal device and the file stored in the server is designated by the storage service software (S107).

  If it is determined in step S107 that a file stored in the server has been specified (“server” in S107), the control unit of the terminal device determines whether the state of the terminal device is stable (normal). Is discriminated (S109).

  If it is determined in step S109 that the state of the terminal device is not stable (No in S109), the control unit of the terminal device gives priority to print processing, and issues a print execution instruction from the server for content to be pulled. The data is transmitted to the MFP (S111). After the printing process is completed, the control unit of the terminal device ends the process without starting the synchronization process (S112).

  If it is determined in step S109 that the state of the terminal device is stable (Yes in S109), the control unit of the terminal device gives priority to print processing, and issues a print execution instruction from the server for content to be pulled. The data is transmitted to the MFP (S113). After completion of the printing process, the control unit of the terminal device starts the synchronization process (S114) and ends the process.

  If it is determined in step S107 that a file stored in the terminal device has been designated (“terminal” in S107), the control unit of the terminal device determines whether the state of the terminal device is stable (normal). Is determined (S117).

  If it is determined in step S117 that the state of the terminal device is not stable (No in S117), the control unit of the terminal device gives priority to the printing process and issues a print execution instruction for the content to be pushed from the terminal device. Is transmitted to the MFP (S119). After the printing process is completed, the control unit of the terminal device ends the process without restarting the synchronization process (S120).
