<System configuration>

Referring to FIG. 1, the print system includes MFPs (Multi-Functional Peripherals) 100A, 100B, and 100C as an example of an image forming apparatus, and a PC (Personal Computer) 300 as an example of a client terminal.

The configuration shown in FIG. 2 is an example, and the configuration is not limited to this configuration.
<Overview of operation>
FIG. 3 is a diagram showing an outline of operation in the print system. In this printing system, a printing method (1) called so-called PC printing, in which a job is issued from the PC 300 to any MFP 100 and printed by the MFP 100, a job is issued from the PC 300 to any MFP 100, and the MFP 100 A print method (2) called secure print, which is printed when the authentication is successful, and a job is issued from the PC 300 to any MFP 100, and the MFP 100 prints according to an operation on any MFP 100 at the instructed timing. The printing can be performed by three kinds of methods, namely, a so-called ubiquitous printing (3). The job used for printing (1) and (2) is also called a “normal job”, and the job used for printing (3) is also called a “ubiquitous job”.

  In the print system, these jobs are managed by the operation shown in FIG. That is, referring to FIG. 3, when issuing a ubiquitous job, the PC 300 sets a storage period A for the job (step S1). Information representing the storage period A may be included in the job, or may be stored in the PC 300 in association with the job.

  The PC 300 issues a job to a designated MFP 100 (or a predetermined MFP 100) of the plurality of MFPs (step S2). At this time, the PC 300 issues a normal job and a ubiquitous job separately. As an example, the PC 300 may prepare a flag indicating that the job is a ubiquitous job, defeat the flag for a normal job, and set the flag for a ubiquitous job. As another example, in the case of a ubiquitous job, the PC 300 may issue an identifier indicating that the job is a ubiquitous job. Further, as described above, when information indicating the storage period A is included in the job, the normal job and the ubiquitous job are distinguished depending on whether or not the job includes information indicating the storage period A. Therefore, it can be said that the information itself indicating the storage period A is information for distinguishing the normal job from the ubiquitous job.

  Receiving the job from PC 300, MFP 100 stores the job in the memory (step S3). In MFP 100, a storage period B of the job in the memory is set in advance. Therefore, the MFP 100 stores the received job in the memory during the storage period B. At this time, if the job is a job used for the printing in (1), the MFP 100 performs print processing on the received job, and then deletes the job by deleting it from the memory. Even in the case of a job used for printing in (2) above, when receiving a print instruction during storage, the MFP 100 prints the job, and then deletes the job by deleting it from the memory. In the case of the job used for the printing in (3) above, when the MFP 100 receives a print instruction for itself or another MFP 100, the MFP 100 performs print processing or transfer to the requested other MFP 100, but the job is stored. Will continue.

  When the storage period B elapses after the job is stored in the memory, the MFP 100 determines whether the job is a normal job or a ubiquitous job (step S4). When the job includes a flag indicating whether or not the job is a ubiquitous job, or when an identifier is included, the MFP 100 determines the type by referring to the flag or the identifier. Alternatively, when information indicating the storage period A of the ubiquitous job is included in the job, the MFP 100 confirms whether the information including the storage period A is included in the job, so that the job is a normal job. Whether the job is a ubiquitous job can be determined.

  Then, the MFP 100 executes processing corresponding to the determined job type for the job (step S5). That is, if the job is a normal job, the MFP 100 deletes the job by deleting it from the memory. On the other hand, when the job is a ubiquitous job, the storage period A set for the ubiquitous job is updated, and the storage in the memory is continued. Here, the MFP 100 sets a period obtained by subtracting the storage period B set for the MFP 100 from the storage period A set for the ubiquitous job as a new storage period A for the ubiquitous job. Repair and store again in memory.

  As another example, the MFP 100 may transfer the ubiquitous job to another MFP 100 after updating the storage period A of the ubiquitous job. By doing so, it is possible to reduce a continuous load on the memory of the user. More preferably, the MFP 100 may refer to the free space of the memory of another MFP 100 included in the print system, and transfer it to the MFP 100 having a small free space or the MFP 100 having a large free space ratio. By doing so, it is possible to suppress the load imbalance on the memory in the entire printing system. Of course, the MFP 100 may inquire other MFPs 100 and transfer them according to the order of responses (for example, to the MFP with the fastest response).

  The above operation is based on the premise that MFP 100 is in a power-on state when storage period B has elapsed since the job was stored in the memory. However, in practice, the MFP 100 is turned off before the storage period B elapses after the job is stored in the memory, and the power is turned on again after the storage period B elapses. That is, the storage period B There is a case where the power is turned off at the timing when elapses. In this case, MFP 100 preferably performs the determination and processing described above for a job for which storage period B has already elapsed when the power is turned on. As a result, even if there is a period during which the MFP 100 is powered off, the print system can process a job in a flow substantially similar to the operation of FIG.

<Functional configuration>
FIG. 4 is a block diagram showing a specific example of functional configurations of PC 300 and MFP 100 for managing the job shown in FIG. Each function of FIG. 4 is realized mainly by the CPUs 30 and 10 when the CPU 30 of the PC 300 or the CPU 10 of the MFP 100 reads out the programs stored in the ROMs 31 and 11 and executes them. However, at least a part of the functions may be realized by another device configuration shown in FIG. 2 or a hardware configuration such as an electric circuit (not shown).

  Referring to FIG. 4, CPU 30 of PC 300 distinguishes between setting unit 301 for setting storage period A for a ubiquitous job according to a user operation of input device 35, and distinguishes normal jobs and ubiquitous jobs from MFP 100. An issuing unit 302 for issuing a job. As described above, the issuing unit 302 may distinguish the job type by including information such as a flag or an identifier indicating whether or not the job is a ubiquitous job. The job type may be distinguished by including information to be represented. The issuing unit 302 may include identification information such as a flag and information indicating the storage period A in a printer job language (PJL) command issued to the MFP 100 together with the job.

  As another method, when the issuing unit 302 issues a ubiquitous job, the PJL command storing the print conditions (print settings) of the job and a temporary command that is a copy of the PJL command are sent to the MFP 100 together with the job. You may transmit to. In this system, when an instruction to change the print condition set for the original job is received from the user in response to a print instruction, MFP 100 changes the print condition described in the temporary command and executes printing. By doing so, it is possible to instruct printing using the original print conditions using the original PJL command. In this case, when there is a temporary command (a copy of the PJL command) in the PJL command received together with the job, MFP 100 can determine that the job is a ubiquitous job. Therefore, it can be said that the temporary command is also identification information indicating the type of job.

  Further, referring to FIG. 4, a storage device (memory) such as HDD 13 of MFP 100 includes a job storage unit 131 which is a storage area for storing jobs. In addition, the CPU 10 receives a job input unit 101 for receiving an input of a job issued from the PC 300 via the communication I / F 17, and a job received from the PC 300 as a client device with a predetermined storage period B, memory A storage unit 102 for storing in the memory, a determination unit 103 for determining the type of the job stored in the memory, and a job type for a job whose storage period B has elapsed since being stored in the memory. And a processing unit 104 for performing corresponding processing. When the corresponding job is a normal job, the processing unit 104 discards the job by deleting it from the memory after the storage period B. When the corresponding job is a ubiquitous job, the processing unit 104 updates the storage period A set for the job after the storage period B. That is, the processing unit 104 updates the storage period A set for the job to a period (AB) obtained by subtracting the storage period B set for the MFP 100 from the storage period A. At this time, the processing unit 104 may only update the storage period A while the job is stored in the memory, or the ubiquitous job in which the updated storage period A is set is transmitted via the communication I / F 17. May be sent to another MFP.

<Operation flow>
FIG. 5 is a flowchart showing the flow of operations in PC 300 and MFP 100, respectively. The CPU 30 of the PC 300 or the CPU 10 of the MFP 100 reads out the programs stored in the ROMs 31 and 11 to the RAMs 32 and 12 and executes the operations shown in the flowcharts of FIGS. It is realized by doing. The operation of the PC 300 in FIG. 5 is started when the user instructs an operation for issuing a ubiquitous job from the PC 300. Then, the operation of MFP 100 in FIG. 5 is started when MFP 100 receives a job from PC 300.

  Specifically, referring to FIG. 5, CPU 30 of PC 300 sets storage period A for the target ubiquitous job according to the user operation (step S101). Then, the CPU 30 distinguishes the ubiquitous job from the normal job and issues (transmits) it to the instructed MFP 100 (step S103). Thus, the operation of the PC 300 ends.

  Next, when the CPU 10 of the MFP 100 receives a job from the PC 300 as the client device, the CPU 10 stores the job in the memory (step S201). When the storage period of the job in the memory reaches the storage period B set in the MFP 100 (YES in step S203), the CPU 10 determines the type of the job as a ubiquitous job or a normal job. . If the job is a ubiquitous job (YES in step S205), the CPU 10 compares the storage period A set for the ubiquitous job with the storage period B set for the MFP 100. As a result, when the storage period A is longer than the storage period B (YES in step S207), the CPU 10 updates the storage period A of the job to (AB) (step S209). At this time, the CPU 10 may transfer the ubiquitous job in which the updated storage period A is set to another MFP in the system. At this time, preferably, the CPU 10 checks the remaining memory capacity of all the MFPs and transfers the job to an MFP having a large remaining capacity or an MFP having a high remaining capacity ratio. Alternatively, the CPU 10 may inquire all the MFPs in the system about the transfer destination, and transfer them to the MFP that has the earliest response.

  When the storage period A set for the ubiquitous job is shorter than the storage period B set for the MFP 100 (NO in step S207), the CPU 10 sets the storage period of the job to the MFP 100. It may be deleted from the memory when the storage period B is reached, or may be deleted from the memory when the storage period A is reached before reaching the storage period B (step S211).

  If the job stored in the memory is a normal job (NO in step S205), the CPU 10 deletes the job by deleting it from the memory when the storage period B set in the MFP 100 is reached. (Step S211).

<Effect of Embodiment>
As the system manages jobs as described above, the user can process (print) normal jobs and ubiquitous jobs using the system. In this system, without managing the storage period for each job, both the normal job with no storage period set and the ubiquitous job with the storage period set are stored on the basis of the storage period set in the system in advance. The storage period can be properly managed.

  Furthermore, by making it possible to transfer ubiquitous jobs to other MFPs at the timing when the storage period set in the system elapses, it is possible to prevent uneven storage of jobs among a plurality of MFPs included in this system. And the load on the entire system can be reduced.

<Modification>
In MFP 100 of this system, storage period C for ubiquitous jobs, which is longer than storage period A, may be set in advance separately from storage period A for normal jobs. In this case, when MFP 100 receives a job from PC 300 that is a client terminal, MFP 100 determines the type of the job, and stores it in the memory for a storage period corresponding to the type. That is, if the job from the PC 300 is a ubiquitous job, the MFP 100 stores it in the memory for a storage period C longer than the normal job storage period A, and then discards it.

  In this way, ubiquitous jobs can be uniformly stored in the memory for a longer period than normal jobs with easy processing.

  Further, it is possible to provide a program for causing the MFP 100 and the PC 300 as the client terminal to execute the above management. Such a program is recorded on a computer-readable recording medium such as a flexible disk attached to the computer, a CD-ROM (Compact Disk-Read Only Memory), a ROM, a RAM, and a memory card, and provided as a program product. You can also. Alternatively, the program can be provided by being recorded on a recording medium such as a hard disk built in the computer. A program can also be provided by downloading via a network.

Also good. In that case, the program itself does not include the module, and the process is executed in cooperation with the OS. A program that does not include such a module can also be included in the program according to the present invention.
