The managed print data is transmitted by the information transmitting means in association with the user information. A job holding instruction unit for holding the print job based on the print data in a standby state by transmitting to the image forming apparatus corresponding to the received identification information; When the plurality of pieces of identification information are transmitted by the information transmission unit for the same user information, all the identification information transmitted by the information transmission unit for the user information All the image forming apparatuses corresponding to each of the image forming apparatuses hold the print job based on the print data managed in association with the user information by the print data management unit.

  With this configuration, the printing system of the present invention operates based on the position information of the portable device acquired by the GPS function when transmitting print data managed by the server to the image forming apparatus according to the distance between the apparatuses. Rather than operating on the basis of the identification information transmitted by radio waves by the identification information transmitting means provided in the image forming apparatus and received by the portable device, the processing load on the portable device and the server, and the portable device and Communication load between servers can be reduced.

The information transmission unit transmits the inter-device distance detected by the distance detection unit to the user information in association with the user information, and the server transmits the user transmitted by the information transmission unit. The image corresponding to the identification information transmitted by the information transmission unit in association with the user information, the print job based on the print data managed in association with the print data management unit A specific operation executing means for executing a specific operation for causing the forming apparatus to execute the specific operation executing means; The specific operation is executed stepwise according to the distance between the devices transmitted by the information transmitting means, and the job holding instruction means indicates that the distance between the devices transmitted by the information transmitting means is the print distance. The specific operation execution unit may be a job holding distance for holding a job.

  With this configuration, the printing system of the present invention executes a specific operation for causing the image forming apparatus to execute a print job based on the print data managed by the server in a stepwise manner according to the distance between the apparatuses. Therefore, it is possible to cause the server and the image forming apparatus to execute appropriate processing according to the distance between the apparatuses. In addition, the printing system of the present invention is provided in the image forming apparatus instead of indirectly detecting the inter-device distance by calculating the inter-device distance based on the position information of the portable device acquired by the GPS function. Since the distance between the devices is directly detected based on the intensity of the radio wave transmitted by the identification information transmitting means, the accuracy of the detection of the distance between the devices can be improved.

  Next, the operation of the printing system 10 will be described.

  First, the operation of the computer 20 when transmitting print data to the server 50 will be described.

  When the user instructs to send print data to the server 50, the computer 20 associates the user information of the user with the print data and sends it to the server 50.

  Therefore, the print data management means 53a of the server 50 includes the print data transmitted from the computer 20 in the print data management information 52a in association with the user information transmitted from the computer 20 in association with the print data. .

  Next, the operation of the mobile device 40 when transmitting user information to the server 50 will be described.

  FIG. 8 is a flowchart of the operation of the portable device 40 when receiving tag information transmitted by radio waves by the transmitting device 39.

  As shown in FIG. 8, the identification information receiving unit 45a of the portable device 40 tries to receive the tag information transmitted by radio waves by the transmitting device 39 of the image forming apparatus 30 via the communication unit 43 (S101).

  Next, the identification information receiving unit 45a determines whether tag information other than the tag information that can be received in the previous processing of S101 has been received in the current processing of S101 (S102).

  If the identification information receiving means 45a determines in S102 that tag information other than the tag information that could be received in the previous processing of S101 could not be received in the current processing of S101, it executes the processing of S101.

  If the identification information receiving unit 45a determines in S102 that tag information other than the tag information that has been received in the previous processing of S101 has been received in the processing of this S101, the tag information that has been received in the previous processing of S101. In addition, the user information transmission operation shown in FIG. 9 is started for each of all the tag information that can be received in the current processing of S101 (S103), and the processing of S101 is executed.

  FIG. 9 is a flowchart of the operation of the mobile device 40 when transmitting user information to the server 50.

  As shown in FIG. 9, the distance detection unit 45b of the portable device 40 performs the processing of S101 in the operation shown in FIG. 8 with respect to tag information targeted in the operation shown in FIG. 9 (hereinafter referred to as “target tag information”). One of the distances L1 to L3 is detected as the inter-device distance based on the intensity of the radio wave received in (S111).

  Next, the information transmitting unit 45c associates the user information 44b on the storage unit 44, the target tag information, and the inter-device distance detected in S111 and transmits them to the server 50 (S112).

  Note that when the user information, tag information, and the distance between devices are transmitted from the portable device 40, the print data management unit 53a of the server 50 determines the combination of the transmitted user information, tag information, and the distance between the devices. The print data management information 52a is stored. Here, the print data management means 53a is associated with the user information from the portable device 40 out of the print data associated with the user information transmitted from the portable device 40 in the print data management information 52a. If there is print data in which the IP address or host name of the image forming apparatus associated in the image forming apparatus management information 52b is not associated in the print data management information 52a in the transmitted tag information, this IP The address or host name is associated with this print data in the print data management information 52a. Further, the print data management unit 53a transmits the print data associated with the user information transmitted from the mobile device 40 in the print data management information 52a and the mobile device 40 associated with the user information. If there is already a device-to-device distance associated with both the IP address or host name of the image forming device associated with the received tag information in the image forming device management information 52b, the user information Overwriting is performed with the new device-to-device distance transmitted from the portable device 40 in association therewith.

  The distance detecting unit 45b determines whether or not the target tag information has been received in the process of S101 newly executed in the operation shown in FIG. 8 after the process of S112 (S113).

  If the distance detection unit 45b determines in S113 that the target tag information has been received, the distance L1 to distance L1 as the inter-device distance based on the strength of the radio wave received in the process of S101 in the operation illustrated in FIG. Any of L3 is detected (S114).

  Next, the distance detection unit 45b determines whether or not the inter-device distance detected in the current process of S114 has changed from the previously detected inter-device distance (S115). Here, the device-to-device distance detected last time is the device-to-device distance detected in the processing in S111 when the current processing in S114 is the first processing in S114 after the start of the operation shown in FIG. In addition, when the current processing of S114 is the processing of S114 after the second time after the start of the operation shown in FIG. 9, it is the inter-device distance detected in the previous processing of S114.

  For example, the distance detection unit 45b performs the process in S114 as a result of the user carrying the portable device 40 and approaching the image forming apparatus 30 when the previously detected distance between the apparatuses is the distances L3 and L2. When the distances L2 and L1 are detected as the inter-device distances in FIG. In addition, the distance detection unit 45b performs the process in S114 as a result of the user carrying the portable device 40 away from the image forming apparatus 30 when the previously detected distance between the apparatuses is the distances L1 and L2. When the distances L2 and L3 are respectively detected as the inter-device distances, it is determined that the inter-device distance has changed.

  If the distance detection unit 45b determines in S115 that the inter-device distance has not changed, the process of S113 is executed.

  If it is determined in S115 that the inter-device distance has changed, the information transmission unit 45c executes the process of S112.

  If it is determined in S113 that the target tag information has not been received, the distance detection unit 45b detects the inter-device distance as “unknown” (S116).

  Next, the information transmission unit 45c associates the user information 44b on the storage unit 44, the target tag information, and the inter-device distance detected in S116, and transmits them to the server 50 (S117).

  Note that the print data management unit 53a of the server 50, when the user information, the tag information, and the inter-device distance are transmitted from the portable device 40, as described above, the transmitted user information, the tag information, and the device. The combination of the distances is stored in the print data management information 52a.

  When the process of S117 ends, the information transmission unit 45c ends the operation illustrated in FIG.

  Next, the operation of the server 50 when executing the job execution specific operation will be described.

  FIG. 10 is a flowchart of the operation of the server 50 when executing the job execution specific operation.

  The control unit 53 of the server 50 executes the operation shown in FIG. 10 for each combination of user information and image forming apparatus (IP address or host name) in the print data management information 52a.

  As illustrated in FIG. 10, the specific operation execution unit 53 b of the server 50 determines the target in the print data management information 52 a until it determines that the inter-device distance associated with the target combination has been changed in the print data management information 52 a. It is determined whether the inter-device distance associated with the combination has been changed (S131).

  If the specific operation execution unit 53b determines in S131 that the inter-device distance associated with the target combination in the print data management information 52a has been changed, the specific operation for job execution set for the new inter-device distance is determined. Is executed on the target image forming apparatus (S132), and the process of S131 is executed.

  For example, when the inter-device distance associated with the target combination in the print data management information 52a is changed from “unknown” to the distance L3, the specific operation execution unit 53b returns the target image forming apparatus from the sleep state. The operation is executed as a job execution specific operation. However, if the image forming apparatus is not already in the sleep state before executing the specific operation for job execution, the specific operation execution unit 53b omits the execution of the specific operation for job execution.

  For example, when the inter-device distance associated with the target combination in the print data management information 52a is changed from the distance L3 to the distance L2, the specific operation executing unit 53b sets the target combination in the print data management information 52a. By transmitting the associated print data and the target user information to the target image forming apparatus, a print job based on the print data is associated with the user information and is in a standby state in the image forming apparatus. The operation to be held in is executed as a job execution specific operation. However, the specific operation executing unit 53b associates the print job based on the print data with the user information and holds it in the image forming apparatus before executing the job execution specific operation. The execution of the specific operation for job execution is omitted.

  For example, when the inter-device distance associated with the target combination in the print data management information 52a is changed from the distance L2 to the distance L1, the specific operation executing unit 53b sets the target combination in the print data management information 52a. Rendered printing based on this print data by causing the image forming apparatus to render the print data that is associated with the target user information and is already held in association with the target user information as a print job The operation of associating the job with the user information and causing the image forming apparatus to hold the job in a standby state is executed as a job execution specific operation. However, the specific operation executing unit 53b associates the rendered print job based on the print data with the user information and holds it in the image forming apparatus before executing the job execution specific operation. In this case, the execution of the specific job execution operation is omitted.

  Therefore, a user carrying the portable device 40 logs in to the image forming apparatus 30 with the user information of the user himself / herself through the operation unit 31 of the image forming apparatus 30 and is associated with the user information. By instructing the image forming apparatus 30 to execute the print job held in the standby state via the operation unit 31, the print job held in the standby state in association with the user information is displayed in the image forming apparatus 30. Can be executed. When the execution of the print job is completed, the image forming apparatus 30 notifies the server 50 which print job has been executed.

  FIG. 11 is a flowchart of the operation of the server 50 when the completion of execution of the print job is notified from the image forming apparatus.

  As shown in FIG. 11, the job cancellation unit 53c of the server 50 includes print data management information 52a for print data of a print job notified of completion of execution from the image forming apparatus (hereinafter referred to as “target print data”). The IP address or host name of the image forming apparatus is deleted from the print data management means 53a among the data associated in step S161 (S161).

  Next, whether or not the job cancellation unit 53c holds the print job based on the target print data in an image forming apparatus other than the image forming apparatus that has notified the completion of the execution of the print job based on the target print data. Is determined based on the print data management information 52a (S162).

  If the job canceling unit 53c determines that the job is not held in S162, the operation illustrated in FIG.

  If it is determined in step S162 that the job cancellation unit 53c holds the job, the job cancellation unit 53c holds the print job based on the target print data in addition to the image forming apparatus that has notified the completion of execution of the print job based on the target print data. The execution of this print job by the image forming apparatus (hereinafter referred to as “remaining image forming apparatus”) that has been made to stop is stopped (S163). That is, the job cancellation unit 53c deletes this print job from the remaining image forming apparatus together with the target print data. Further, the job cancellation unit 53c causes the print data management unit 53a to delete the IP address or host name of the remaining image forming apparatus among the data associated with the target print data in the print data management information 52a.

  The job cancellation unit 53c ends the operation shown in FIG. 11 after the processing of S163.

  FIG. 12 is a diagram illustrating an example of an inter-device distance when the server 50 holds the same print job in a plurality of image forming apparatuses in a standby state.

  In FIG. 12, an image forming apparatus 30a including a transmitting device 39a and an image forming apparatus 30b including a transmitting device 39b are illustrated as image forming apparatuses. Each of the image forming apparatuses 30 a and 30 b has the same configuration as the image forming apparatus 30.

  As shown in FIG. 12, when the information transmission unit 45c (see FIG. 3) of the portable device 40 exists at a distance L2 in the image forming apparatus 30a and a distance L2 in the image forming apparatus 30b, The user information 44b, the tag information of the transmission device 39a, and the distance L2 as the distance between the devices are transmitted to the server 50 (S112), and the user information 44b on the storage unit 44 and the tag information of the transmission device 39b are transmitted. And the distance L2 as the inter-device distance is transmitted to the server 50 (S112). Therefore, the print data management means 53a of the server 50 stores the combination of user information, tag information and inter-device distance transmitted from the portable device 40 in the print data management information 52a. In addition, the specific operation execution unit 53b of the server 50 forms a print job based on the print data associated with the user information of the mobile device 40 in the print data management information 52a, corresponding to the tag information of the transmission device 39a. The apparatus 30a and the image forming apparatus 30b corresponding to the tag information of the transmission apparatus 39b are held in association with the user information (S132).

  When this print job is executed by one of the image forming apparatus 30a and the image forming apparatus 30b, the job cancellation unit 53c of the server 50 executes the execution of this print job by the other of the image forming apparatus 30a and the image forming apparatus 30b. Stop (S163).

  As described above, the printing system 10 performs the job execution specific operation by the server 50 such as transmitting the print data managed by the server 50 to the image forming apparatus according to the distance between the apparatuses (S132). In this case, the tag information is not transmitted based on the position information of the portable device 40 acquired by the GPS function, but is transmitted by radio waves by the transmitting device 39 provided in the image forming apparatus 30 and received by the portable device 40. Therefore, the processing load on the mobile device 40 and the server 50 and the communication load between the mobile device 40 and the server 50 can be reduced. Therefore, the printing system 10 can reduce the load when the image forming apparatus 30 executes a print job based on the print data managed by the server 50.

  When this print job is executed by some image forming apparatuses among a plurality of image forming apparatuses that have held print jobs based on the same print data, the printing system 10 Since the execution of the print job by the remaining image forming apparatuses is stopped (S163), the print job can be deleted from each of the plurality of image forming apparatuses. Therefore, the printing system 10 can effectively use the storage areas of the plurality of image forming apparatuses.

  Since the printing system 10 executes the job execution specific operation step by step according to the distance between the apparatuses, the server 50 and the image forming apparatus 30 can execute appropriate processing according to the distance between the apparatuses. .

  The server 50 does not have to execute the job execution specific operation step by step according to the distance between the apparatuses. For example, the server 50 returns the image forming apparatus 30 from the sleep state when tag information transmitted by radio waves from the transmitting apparatus 39 provided in the image forming apparatus 30 is received by the portable device 40. The print data managed in association with the user information transmitted from the portable device 40 together with the tag information in the print data management information 52a and the user information are transmitted to the image forming apparatus 30, and the print data May be executed by causing the image forming apparatus 30 to render the print job based on the print data in association with the user information and hold the image forming apparatus 30 in a standby state. .

  The printing system 10 returns the image forming apparatus 30 that executes the print job based on the print data managed by the server 50 from the sleep state according to the distance between the apparatuses. Can be started early.

  Since the printing system 10 transmits the print data managed by the server 50 to the image forming apparatus 30 according to the distance between the apparatuses, the printing system 10 causes the image forming apparatus 30 to start execution of the print job based on the print data at an early stage. be able to.

  The printing system 10 causes the image forming apparatus 30 to render the print data managed by the server 50 in accordance with the inter-device distance, and thus causes the image forming apparatus 30 to end the execution of the print job based on the print data at an early stage. be able to.

  Note that the server 50 may execute the above-described operation according to a distance between apparatuses different from the above-described example as the job execution specific operation. For example, in the above-described example, the distance L2 is a job holding distance for holding a print job, but the distance L1 or L3 may be a job holding distance.

  Further, the server 50 may employ an operation other than the above-described operation as the job execution specific operation.

  For example, when the inter-device distance associated with the target combination in the print data management information 52a is changed from the distance L2 to the distance L1, the specific operation execution unit 53b of the server 50 selects the target combination in the print data management information 52a. An operation for causing the image forming apparatus to execute a print job based on the print data associated with the print job that is already held in association with the target user information in the target image forming apparatus. It may be executed as a specific operation for execution. With this configuration, the printing system 10 causes the image forming apparatus 30 to execute a print job based on the print data managed by the server 50 in accordance with the inter-device distance, so that the image forming apparatus 30 executes this print job. It can be terminated early.

  Note that the printing system 10 may set in the server 50 which job execution specific operation is executed according to which device distance, or may be set in the application 44 a of the mobile device 40. good. When set in the application 44 a of the mobile device 40, the information transmission unit 45 c of the mobile device 40 performs job execution that is executed by the server 50 when transmitting the user information 44 b, tag information, and inter-device distance to the server 50. The content of the specific operation may be transmitted to the server 50.

  The printing system 10 does not indirectly detect the inter-device distance by calculating the inter-device distance based on the position information of the portable device 40 acquired by the GPS function, but the transmission provided in the image forming apparatus 30. Since the inter-device distance is directly detected based on the intensity of the radio wave transmitted by the device 39, the accuracy of detecting the inter-device distance can be improved.

  Since the printing system 10 includes a transmission device that operates independently of the image forming apparatus, the tag information is transmitted by radio waves even in an image forming apparatus that cannot transmit tag information by radio waves. By attaching a transmitter capable of transmitting the tag information, the image forming apparatus can transmit the tag information by radio waves at low cost.

  Note that the image forming apparatus need not include a transmitting device that operates independently of the image forming apparatus itself if the image forming apparatus itself can transmit the tag information by radio waves.
