The predetermined amount of paper is the lower limit value of the printing paper set in the printer 19. When the remaining amount of paper is less than the predetermined amount of paper, it can be determined that there is a possibility that the print paper will run out during printing by the printer 19. The predetermined amount of ink and the predetermined amount of paper may be stored in advance by the user. Further, since the configuration of the storage unit 33 is the same as that of the storage unit 73 of the relay server 71, a detailed description thereof is omitted here.

  The operation of the printing system 1 according to the present embodiment will be described with reference to FIGS. In the description example of the present embodiment, a case where a print reservation is made by a user of the first mobile phone 10 (a general user of the MFP 51) will be described. A case will be described in which an inquiry as to whether or not printing based on the print reservation may be executed by the MFP 51 is made to the user of the second mobile phone 9 (an administrator of the MFP 51).

  An outline of the printing system 1 will be described. When printing is performed from the first mobile phone 10, not the print data itself but a print reservation is first notified to the relay server 71. The relay server 71 stores that there is a print reservation. The relay server 71 notifies the MFP 51 of the presence / absence of a print reservation when the MFP 51 confirms the presence / absence of a print reservation. When the MFP 51 is set to execute the print confirmation process (S 172), the MFP 51 transmits a print propriety inquiry to the second mobile phone 9 and accepts an input of the print propriety result at the button input unit 38 of the MFP 51. The MFP 51 has a print reservation, and when a print permission result “print ready” is acquired, transmits a print data request to the relay server 71. When receiving the print data request from the MFP 51, the relay server 71 requests the first mobile phone 10 for the print data. When the relay server 71 receives the print data from the first mobile phone 10, the relay server 71 transfers the received print data to the MFP 51. The MFP 51 receives the print data and executes printing.

<Operation of relay server>
The operation of the relay server 71 will be described with reference to the flowcharts of FIGS. The flow in FIGS. 2 to 5 is a flow that always operates. In S <b> 210, the CPU 72 determines whether or not a use registration request has been received from the MFP 51. The use registration request is a request to start use registration processing (registration processing of various information for using the printing system 1). Note that the use registration process may be performed once at the start of use of the printing system 1. When the use registration request is received (S210: YES), the process proceeds to S212.

  In S <b> 212, the CPU 72 reads MFP identification information from the use registration request received from the MFP 51 and stores it in the storage unit 73. In S <b> 214, the CPU 72 generates ID information and stores it in the storage unit 73. In S <b> 216, the CPU 72 causes the communication unit 74 to transmit the ID information and the relay server address to the MFP 51. Further, the MFP 51 is requested for a password, a first mobile phone address, and a second mobile phone address. In S <b> 218, the CPU 72 determines whether a password, a first mobile phone address, and a second mobile phone address have been received from the MFP 51. If not received (S218: NO), the process returns to S218, and if received (S218: YES), the process proceeds to S220.

  In S <b> 220, the CPU 72 stores the received password, first mobile phone address, and second mobile phone address in the storage unit 73. Then, correspondence information that associates the MFP identification information with the ID information and the password is stored in the table storage area 12 b of the storage unit 73. Further, the status “initial state” is stored in association with the correspondence information. Also, information specifying the MFP 51 (MFP identification information, ID information, password), information specifying the first mobile phone 10 (first mobile phone address), and information specifying the second mobile phone 9 (second mobile phone) Corresponding information for associating (address) is also stored in the table storage area 12 b of the storage unit 73.

  In S <b> 222, the CPU 72 causes the communication unit 74 to transmit a registration completion response to the MFP 51. Then, the process returns to S210.

  On the other hand, when the use registration request is not received in S210 (S210: NO), the process proceeds to S230. In S <b> 230, the CPU 72 determines whether a print reservation has been received from the first mobile phone 10. The print reservation is information indicating that a print reservation is made. The print reservation is information including the first mobile phone address of the first mobile phone 10, the ID information and password of the MFP 51, and the print thumbnail image data. The print thumbnail image data is data for displaying a reduced view of an image to be printed based on a print reservation. If a print reservation has been received (S230: YES), the process proceeds to S232.

  In S232, the CPU 72 accesses the table storage area 12b, and specifies MFP identification information corresponding to the ID information and password included in the print reservation. Then, the print status corresponding to the specified MFP identification information is changed to “print reservation state”. Further, the print thumbnail image data included in the print reservation is stored in the storage unit 73. In S <b> 234, the CPU 72 causes the communication unit 74 to transmit a reservation acceptance notification to the first mobile phone 10. Then, the process returns to S210. If it is determined in S232 that the first mobile phone address included in the print reservation does not match the first mobile phone address corresponding to the ID information and password included in the print reservation, the process returns to S210 (print reservation is changed). I will not admit it).

  On the other hand, in S230, when the print reservation is not received from the first mobile phone 10 (S230: NO), the process proceeds to S240 (FIG. 3). In S <b> 240, the CPU 72 determines whether a print reservation confirmation is received from the MFP 51.

  In S282, the CPU 72 accesses the table storage area 12b and specifies MFP identification information corresponding to the ID information and password included in the print data acquisition. In S284, the CPU 72 determines whether or not the current print status stored in the table storage area 12b is “waiting for data provision”. If the print status is not “data provision wait state” (S284: NO), the process proceeds to S289, information indicating that print data is not stored is transmitted to the MFP 51, and the process returns to S210. If the print status is “waiting for data provision” (S284: YES), the process proceeds to S286.

  In S286, the CPU 72 causes the MFP 51 to transmit print data using the communication unit 74. In S288, the CPU 72 changes the print status to “initial state”. Then, the process returns to S210 (FIG. 2).

  If it is determined in S280 that print data acquisition has not been received from the MFP 51 (S280: NO), the process proceeds to S292 (FIG. 5). In S <b> 292, the CPU 72 determines whether a print permission confirmation has been received from the MFP 51. The print permission confirmation is information for making a confirmation inquiry as to whether or not the relay server 71 has received a print permission result, which is a response to a print permission inquiry (described later), from the second mobile phone 9. The print permission confirmation is information including ID information for identifying the MFP 51 and a password. If a print permission confirmation has been received (S292: YES), the process proceeds to S293.

  In S293, the CPU 72 accesses the table storage area 12b and specifies MFP identification information corresponding to the ID information and password included in the print permission confirmation. In S294, the CPU 72 determines the contents of the printability result corresponding to the specified MFP identification information. If the printability result is “printable” (S294: “printable”), the process proceeds to S295, the printable result indicating “printable” is transmitted to the MFP 51 using the communication unit 74, and the process returns to S210. . On the other hand, if the printability result is “not printable” (S294: “not printable”), the process proceeds to S296, and the printability result indicating “not printable” is transmitted to the MFP 51 using the communication unit 74. Return to. If the printability result has not yet been received from the second mobile phone 9 (S294: “Undecided”), the process returns to S210 without transmitting the printability result to the MFP 51.

  On the other hand, if it is determined in S292 that the print permission confirmation has not been received from the MFP 51 (S292: NO), the process proceeds to S297. In S <b> 297, the CPU 72 determines whether a print permission inquiry has been received from the MFP 51. The print permission inquiry is made as to whether or not the MFP 51 can execute printing based on the print reservation made by the user of the first mobile phone 10 (general user of the MFP 51). This is information for making an inquiry to the administrator. The print permission inquiry is information including ID information of the MFP 51 and a password. When a print permission inquiry is received (S297: YES), the process proceeds to S298.

  In S298, the CPU 72 generates a specific URL (Uniform Resource Locator). The specific URL is information for accessing the print thumbnail image data stored in the storage unit 73 of the relay server 71 from the second mobile phone 9 via the Internet 70. In S <b> 300, the CPU 72 causes the communication unit 74 to send a print permission inquiry and a specific URL to the second mobile phone 9. Specifically, a print permission inquiry and a specific URL are transmitted to the second mobile phone 9 by e-mail using the second mobile phone address. Then, the process returns to S210.

  When the second mobile phone 9 receives the print availability inquiry from the relay server 71, the second mobile phone 9 displays the contents of the print availability inquiry on the panel of the second mobile phone 9. As an example of the display content, a print reservation is made in the MFP 51 by the user of the first mobile phone 10 (general user of the MFP 51. Is it OK to execute printing in the MFP 51?) Display. The second mobile phone 9 receives an input indicating whether printing can be executed. When the second mobile phone 9 receives an input indicating whether or not printing is possible from the user (administrator of the MFP 51), the second mobile phone 9 transmits a printing availability result (“printing is possible” or “printing is impossible”) to the relay server 71. Whether or not the relay server 71 has received the printability result transmitted from the second mobile phone 9 is determined in S306 described later.

  On the other hand, if it is determined in S297 that a print permission inquiry has not been received from the MFP 51 (S297: NO), the process proceeds to S302. In S <b> 302, the CPU 72 determines whether URL access has been performed from the second mobile phone 9. The URL access is access based on the specific URL generated in S298. When the URL access is accepted (S302: YES), the process proceeds to S304. In S <b> 304, the CPU 72 uses the communication unit 74 to transmit the print thumbnail image data stored in the storage unit 73 to the second mobile phone 9. Then, the process returns to S210. As a result, the second mobile phone 9 can display a thumbnail of the print image on the second mobile phone 9. Therefore, the user of the second mobile phone (an administrator of the MFP 51) can determine whether or not the MFP 51 can print based on the thumbnail of the print image.

  On the other hand, when it is determined in S302 that the URL access is not performed from the second mobile phone 9, the process proceeds to S306. In S <b> 306, the CPU 72 determines whether or not a printable result is received from the second mobile phone 9. The printability result is information including the second mobile phone address of the second mobile phone 9 and the ID information and password of the MFP 51. If a printability result is received (S306: YES), the process proceeds to S308.

  In S308, the CPU 72 accesses the table storage area 12b, and identifies MFP identification information corresponding to the ID information and password included in the printability result. Then, in association with the specified MFP identification information, the printability result (“printable” or “printable”) is stored in the table storage area 12b. Then, the process returns to S210.

<Operation of MFP>
The operation of the MFP 51 will be described with reference to the flowcharts of FIGS. The flow in FIGS. 6 to 10 is a flow that always operates. In S108 of FIG. 6, the CPU 32 sets a print reservation presence / absence confirmation timer. The print reservation presence / absence confirmation timer is a timer for determining whether or not the second waiting time has elapsed. In S110, the CPU 32 determines whether or not the use registration process has been started. The use registration process is a process for acquiring ID information and a relay server address and registering a password, a first mobile phone address, and a second mobile phone address in order to use the printing system 1. The registration of various types of information is performed by accepting an input operation by the user via the button input unit 38. When the use registration process is started (S110: YES), the process proceeds to S112.

  In S <b> 112, the CPU 32 causes the wireless transmission / reception unit 36 to transmit a use registration request to the relay server 71. The use registration request includes MFP identification information. In S <b> 114, the CPU 32 determines whether or not ID information and a relay server address are received as a response from the relay server 71. If not received (S114: NO), the process returns to S114. If received (S114: YES), the process proceeds to S116. In S <b> 116, the CPU 32 stores the received ID information and relay server address in the storage unit 33. In S118, the CPU 32 causes the panel 39 to display the ID information and the relay server address. In addition, an input screen for a password, a first mobile phone address, and a second mobile phone address is displayed on the panel 39.

  In S <b> 120, the CPU 32 determines whether the password, the first mobile phone address, and the second mobile phone address have been input via the button input unit 38. When it is not input (S120: NO), the process returns to S120, and when it is input (S120: YES), the process proceeds to S122.

  In S <b> 122, the CPU 32 causes the wireless transmission / reception unit 36 to transmit the input password, the first mobile phone address, and the second mobile phone address to the relay server 71. In S124, the CPU 32 determines whether or not a registration completion response from the relay server has been received. If not received (S124: NO), the process returns to S114, and if received (S124: YES), the process proceeds to S126. In S <b> 126, the CPU 32 stores the password in the storage unit 33.

  In S128, the CPU 32 displays a print confirmation setting screen on the panel 39 and accepts a print confirmation setting input. The print confirmation setting is for the user of the second mobile phone 9 or a user in the vicinity of the MFP 51 as to whether or not the MFP 51 executes printing when a response with reservation is received from the relay server 71 (S168: YES). On the other hand, it is a setting for whether or not to execute a confirmation inquiry. The print confirmation setting includes various settings such as “confirmation not necessary”, “always confirm”, “confirm when ink is low”, and “confirm when paper is low”. If the setting input for the print confirmation setting has not been accepted (S128: NO), the process returns to S128, and if accepted (S128: YES), the process proceeds to S130. In S <b> 130, the CPU 32 stores the accepted print confirmation setting in the storage unit 33. Thereby, the use registration process is completed, and the process returns to S110.

  On the other hand, when the use registration process is not started in S110 (S110: NO), the process proceeds to S140 (FIG. 7). In S140, the CPU 32 determines whether or not the print data acquisition time has come by using the print data acquisition timer. The print data acquisition timer is a timer for determining whether or not the first standby time has elapsed, and is set in S148 and S176 described later. If the print data acquisition time has arrived (S140: YES), the process proceeds to S142.

  In S <b> 142, the CPU 32 causes the wireless transmission / reception unit 36 to transmit print data acquisition to the relay server 71. In S <b> 144, the CPU 32 determines whether information indicating that print data is not stored or print data has been received from the relay server 71. If not received (S144: NO), the process returns to S144. If received (S144: YES), the process proceeds to S146.

  In S146, the CPU 32 determines whether the print data has been received. If not received (S146: NO), the process proceeds to S148, and the CPU 32 sets a print data acquisition timer and cancels other timers. Then, the process returns to S110 (FIG. 6). If print data can be received in S146 (S146: YES), the process proceeds to S150, and the CPU 32 causes the printer 19 to execute printing using the print data. In S152, the CPU 32 sets a print reservation presence / absence confirmation timer and cancels other timers. Then, the process returns to S110 (FIG. 6).

  On the other hand, if the print data acquisition time has not arrived in S140 (S140: NO), the process proceeds to S160 (FIG. 8). In S <b> 160, the CPU 32 determines whether or not the time for confirming whether or not a print reservation has arrived by using a print reservation presence / absence confirmation timer. The print reservation presence / absence confirmation timer is set in S108, S152, and S170. If it is not time to confirm whether or not there is a print reservation (S160: NO), the process proceeds to S162, and other processes (such as a process using the scanner 20) are executed, and the process returns to S110 (FIG. 6). On the other hand, if it is time to confirm whether or not there is a print reservation (S160: YES), the process proceeds to S164. In S <b> 164, the CPU 32 causes the wireless transmission / reception unit 36 to transmit a print reservation presence confirmation to the relay server 71.

  The second waiting time of the print reservation presence / absence confirmation timer is preferably set longer than the first waiting time of the print data acquisition timer. Thus, the execution frequency of polling (S142) for acquiring print data is higher than the execution frequency of polling (S164) for confirming whether or not the print reservation has been made by the first mobile phone 10. Can be high.

  In S166, the CPU 32 determines whether or not response information from the relay server 71 has been received. If not received (S166: NO), the process returns to S166, and if received (S166: YES), the process proceeds to S168.

  In S168, the CPU 32 determines whether or not a print reservation is being made. Specifically, it is determined whether the response information received from the relay server 71 represents the status “print reservation is present”. If the status is “no print reservation” (S168: NO), the process proceeds to S170, and the CPU 32 sets a print reservation existence confirmation timer. Then, the process returns to S110 (FIG. 6). If the status is “print reservation present” in S168 (S168: YES), the process proceeds to S172. In S172, the CPU 32 executes print confirmation processing. The print confirmation process determines whether the MFP 51 performs printing based on the print reservation made by the user of the first mobile phone 10 (general user of the MFP 51) (administrator of the MFP 51). ) Or a user in the vicinity of the MFP 51 to make a confirmation inquiry. The contents of the print confirmation process will be described later.

  In S174, the CPU 32 determines whether or not the print data acquisition timer has been set. If it has been set (S174: YES), the process returns to S110, and if it has not been set (S174: NO), the process proceeds to S176. In S176, the CPU 32 sets a print data acquisition timer and cancels other timers. Then, the process returns to S110 (FIG. 6).

<Print confirmation process>
The print confirmation process performed in S172 will be described with reference to the flowcharts of FIGS. In S <b> 410, the CPU 32 reads out the contents of the print confirmation setting from the storage unit 33. In S412, the CPU 32 determines whether or not the content of the print confirmation setting is “confirmation unnecessary”. If “confirmation is not required” (S412: YES), it is determined that there is no need to make a confirmation inquiry to the user of the second mobile phone 9 (an administrator of the MFP 51) or a user in the vicinity of the MFP 51. , The process proceeds to S422. On the other hand, when the content of the print confirmation setting is not “confirmation unnecessary” (S412: NO), the process proceeds to S414.

  In S414, the CPU 32 determines whether or not the content of the print confirmation setting is “always confirm”. If “Always confirm” (S414: YES), regardless of the state of the MFP 51, a confirmation inquiry is made to the user of the second mobile phone 9 (an administrator of the MFP 51) or a user in the vicinity of the MFP 51. Is determined to be executed. Therefore, the process proceeds to S416, and the CPU 32 displays a confirmation screen on the panel 39. The confirmation screen displays that the user of the second mobile phone 9 is inquired about whether or not the MFP 51 can execute printing. Further, the confirmation screen displays that the button input unit 38 of the MFP 51 accepts an input about whether or not the MFP 51 can execute printing.

In S <b> 418, the CPU 32 causes the wireless transmission / reception unit 36 to transmit a print permission confirmation to the relay server 71. In S <b> 419, the CPU 32 determines whether a printability result has been received from the relay server 71, or whether an input of the printability result has been received by the button input unit 38. If the print permission / rejection result is not received or input is not received (S419: NO), the process returns to S418. If the reception or input is received (S419: YES), the process proceeds to S420.

  In S <b> 420, the CPU 32 determines whether or not the content of the printability result received from the second mobile phone 9 or the content of the printability result received by the button input unit 38 is “printable”. If the printability result is not “printable” (S420: NO), the process proceeds to S174 (FIG. 8) without printing. On the other hand, if the printability result is “printable” (S420: YES), the process proceeds to S422. In S <b> 422, the CPU 32 causes the wireless transmission / reception unit 36 to transmit a print data request to the relay server 71. Then, the process proceeds to S174 (FIG. 8).

  On the other hand, if the content of the print confirmation setting is not “always confirm” in S414 (S414: NO), the process proceeds to S430 (FIG. 10). In S430, the CPU 32 determines whether or not the content of the print confirmation setting is “confirm when the amount of remaining ink is low”. In the case of “confirm when ink level is low” (S430: YES), when the ink level of the printer 19 is low, the user of the second mobile phone 9 (an administrator of the MFP 51) or the vicinity of the MFP 51 It is determined that it is a case where a confirmation inquiry is executed for the user who is in the area, and the process proceeds to S432. In S <b> 432, the CPU 32 determines whether or not the remaining amount of ink used in the printer 19 is smaller than a predetermined ink predetermined amount. When multiple types of ink are used, the remaining amount is determined for each of the multiple types of ink. If the remaining amount of ink is not less than the predetermined amount of ink (S432: NO), the process proceeds to S422 (FIG. 9). On the other hand, if the ink remaining amount is less than the predetermined amount of ink (S432: YES), it is determined that there is a possibility that ink will run out during printing by the printer 19, and the process proceeds to S434. In S434, the CPU 32 displays a confirmation screen on the panel 39. Since the display content of the confirmation screen is the same as the content described above in S416, the description is omitted here.

  In S <b> 435, the CPU 32 causes the wireless transmission / reception unit 36 to transmit a print permission inquiry to the relay server 71. In S <b> 436, the CPU 32 determines whether a printability result has been received from the relay server 71 or whether an input of the printability result has been received by the button input unit 38. If the print permission / rejection result has not been received or input has not been received (S436: NO), the process returns to S436, and if reception or input has been received (S436: YES), the process proceeds to S438.

  In S <b> 438, the CPU 32 determines whether the content of the printability result received from the second mobile phone 9 or the content of the printability result received by the button input unit 38 is “printable”. If the printability result is not “printable” (S438: NO), the process proceeds to S174 (FIG. 8), and if the printability result is “printable” (S438: YES), the process proceeds to S440. In S440, the CPU 32 executes a new ink test. Specifically, a message indicating that the ink cartridge whose ink remaining amount is smaller than a predetermined amount is replaced with a new cartridge is displayed on the panel 39. When the cartridge is exchanged, the test pattern is printed. In S442, the CPU 32 determines whether the test printing has been normally completed. If not completed normally (S442: NO), the process proceeds to S174 (FIG. 8), and if completed normally (S442: YES), the process proceeds to S422.

  On the other hand, if the content of the print confirmation setting is not “confirm when ink level is low” in S430 (S430: NO), the process proceeds to S450. In S450, the CPU 32 determines whether or not the content of the print confirmation setting is “confirm when the remaining amount of paper is low”. If it is not “confirm when the remaining amount of paper is low” (S450: NO), the process proceeds to S174 (FIG. 8). On the other hand, if it is “confirm when the remaining amount of paper is low” (S450: YES), the user of the second mobile phone 9 (the administrator of the MFP 51) It is determined that it is a case of making a confirmation inquiry to a user in the vicinity of the MFP 51, and the process proceeds to S452.

  In S452, the CPU 32 determines whether or not the number of sheets used in the printer 19 is less than a predetermined amount of sheets. If the remaining amount of paper is not less than the predetermined amount of paper (S452: NO), the process proceeds to S422 (FIG. 9). On the other hand, if the remaining amount of paper is less than the predetermined amount of paper (S432: YES), it is determined that there is a possibility that the paper will run out during printing by the printer 19, and the process proceeds to S454. In addition, since the processing content of S454-S458 is the same as that of each of S434-S438 mentioned above, description is abbreviate | omitted here.

<Operation of the first mobile phone>

Then, the process returns to S310.

  On the other hand, if the print reservation process is not started in S310 (S310: NO), the process proceeds to S330 (FIG. 12). In S <b> 330, the CPU 11 determines whether a print data request is received from the relay server 71. If a print data request has been received (S330: YES), the process proceeds to S331. In step S <b> 331, the CPU 11 causes the relay server 71 to transmit information indicating that the print data request has been received, using the mobile phone transmission / reception unit 22.

  In S336, the CPU 11 causes the mobile phone transmission / reception unit 22 to transmit the print data selected in S312 to the relay server 71 using the relay server address. The print data is transmitted by e-mail using the relay server address as the transmission destination and the first mobile phone address as the transmission source. In S <b> 337, the CPU 11 determines whether information indicating that the reception of the print data is completed is received from the relay server 71. If not received (S337: NO), the process returns to S337, and if received (S337: YES), the process returns to S310.

  On the other hand, if a print data request has not been received in S330 (S330: NO), the process proceeds to S340. In S340, the CPU 11 determines whether or not the relay server address registration process has been started. The relay server address registration process is a process of registering a relay server address (e-mail address of the relay server 71) for using the printing system 1. If the use registration process is not started (S340: NO), the process proceeds to S350, other processes are executed, and the process returns to S310 (FIG. 8). On the other hand, when the use registration process is started (S340: YES), the process proceeds to S342.

  In S <b> 342, the CPU 11 displays a relay server address input screen on the panel 18. In S <b> 344, the CPU 11 determines whether or not a relay server address has been input via the button input unit 17. If it is not input (S344: NO), the process returns to S344. If it is input (S344: YES), the process proceeds to S346. In S346, the CPU 11 stores the input relay server address in the storage unit 12. Then, the process returns to S310.

<Operation example of printing system>
An operation example of the printing system 1 will be described with reference to the sequence diagrams of FIGS. 13 and 14. As an example, a case will be described in which the content of the print confirmation setting is set to “always confirm”. Further, as an example, a case will be described in which the user of the second mobile phone 9 (an administrator of the MFP 51) inputs a print permission result “printable”.

  When the use registration process is started in the MFP 51 at time T1 (S110: YES), the MFP 51 transmits a use registration request to the relay server 71 (S112). When the relay server 71 receives the use registration request (S210: YES), MFP identification information is read from the use registration request and stored in the storage unit 73 (S212), and ID information is generated and stored in the storage unit 73 (S212). S214). The relay server 71 transmits the ID information and the relay server address to the MFP 51 (S216). The MFP 51 stores the received ID information and relay server address in the storage unit 33 (S116). The MFP 51 transmits the input password, first mobile phone address, and second mobile phone address to the relay server 71 (S122). The relay server 71 stores the received password, first mobile phone address, and second mobile phone address in the table storage area 12b (S220). Then, the print status is set to “initial state”.

  At time T2, the MFP 51 transmits a print reservation presence confirmation to the relay server 71 in response to the arrival of the print reservation presence confirmation time (S160: YES) (S164). When the relay server 71 receives the print reservation presence confirmation (S240: YES), the relay server 71 confirms the print status (S244). Since the print status is not “print reservation state” (S244: NO), response information indicating “no print reservation” is transmitted to the MFP 51 (S248). The MFP 51 determines that a print reservation has not been made (S168: NO), and sets a print reservation presence / absence confirmation timer (S170).

  When the print reservation process is started on the first mobile phone 10 at time T3 (S310: YES), the print reservation is transmitted to the relay server 71 (S316). When the relay server 71 receives the print reservation (S230: YES), the relay server 71 changes the print status to “print reservation state” (S232).

  At time T4, in response to the arrival of the print reservation presence confirmation time (S160: YES), the MFP 51 transmits a print reservation presence confirmation to the relay server 71 (S164). When the relay server 71 receives the print reservation presence confirmation (S240: YES), it confirms the print status again (S244). Since the print status is “print reservation state” (S244: YES), response information indicating “print reservation is present” is transmitted to the MFP 51 (S246). The MFP 51 determines that a print reservation has been made (S168: YES), and executes a print confirmation process (S172).

  Since the content of the print confirmation setting is set to “always confirm” (S414: YES), the MFP 51 displays a confirmation screen on the panel 39 (S416). The MFP 51 transmits a print permission inquiry to the relay server 71 (S417). When the relay server 71 receives a print permission inquiry from the MFP 51 (S297: YES), the relay server 71 transmits a print permission inquiry and a specific URL to the second mobile phone 9 (S300). When the second mobile phone 9 receives a print permission inquiry from the relay server 71, the second mobile phone 9 displays the contents of the print permission inquiry on the panel of the second mobile phone 9 and accepts an input of whether print execution is possible. When the second mobile phone 9 receives an input of “printable” from the user (administrator of the MFP 51), the second mobile phone 9 transmits a printable result (“printable”) to the relay server 71.

  When the relay server 71 receives the printability result from the second mobile phone 9 (S306: YES), the relay server 71 stores the printability result (“printable”) in the table storage area 12b (S308). The MFP 51 periodically transmits a print permission confirmation to the relay server 71. (S418). When the relay server 71 receives a print permission confirmation from the MFP 51 (S292: YES), the relay server 71 transmits a print permission result indicating “printing permitted” to the MFP 51 (S295). When the MFP 51 receives the print permission result indicating “printing is possible” (S420: YES), the MFP 51 transmits a print data request to the relay server 71 (S422). The relay server 71 determines that the print data request has been received from the MFP 51 (S260: YES), and transmits the print data request to the first mobile phone 10 (S268). The first mobile phone 10 receives the print data request (S330: YES).

  At time T5, in response to the arrival of print data acquisition time (S140: YES), the MFP 51 transmits print data acquisition to the relay server 71 (S142). When receiving the print data acquisition (S280: YES), the relay server 71 confirms the print status (S282). Since the print status is not “data provision waiting state” (S284: NO), information indicating that the print data is not stored is transmitted to the MFP 51 (S289).

  When print data is transmitted from the first mobile phone 10 to the relay server 71 at time T6 (S336), the relay server 71 receives and stores the print data (S270: YES).

  At time T7, in response to the arrival of the print data acquisition time (S140: YES), the MFP 51 transmits the print data acquisition to the relay server 71 again (S142). When receiving the print data acquisition (S280: YES), the relay server 71 confirms the print status (S282). Since the print status is “waiting for data provision” (S284: YES), the print data is transmitted to the MFP 51 (S286), and the print status is changed to “initial state” (S288). The MFP 51 receives the print data (S146: YES), and executes printing using the print data (S150).

  The effects of the printing system 1 according to the description example of the present embodiment described above will be described. In the MFP 51 described in the present application, when a print reservation is received from the first mobile phone 10 (S168: YES), on condition that the print enable / disable result of “printable” is received from the second mobile phone 9, or On the condition that the input of the “printable” printability result is accepted by the button input unit 38 of the MFP 51 (S420: YES), the image data used for printing is requested to the relay server 71 (S422). That is, it can be controlled not to acquire the print data until the “printable” printability result is acquired. As a result, whether or not the print job reserved by the first mobile phone 10 can be executed can be controlled from the second mobile phone 9 or the MFP 51. Therefore, it is possible to cope with a case where the MFP 51 does not want to immediately execute printing. As an example of the case where the MFP 51 does not want to immediately execute printing, when the remaining amount of ink or printing paper is low (because there is no ink or printing paper during the printing with the MFP 51, an error state is caused in which printing cannot be continued. And the case where the memory is consumed for the received print data). Further, there is a case where the remaining amount of ink or printing paper is zero (when the MFP 51 is in an error state where printing cannot be started and thus the memory is consumed for the received print data).

  In the relay server 71 described in the present application, in response to receiving a print reservation from the first mobile phone 10 (S230: YES) and receiving a print data request from the MFP 51 (S260: YES), the first mobile phone A print data request is transmitted to 10 (S268). In response to receiving the print data request (S330: YES), the first mobile phone 10 transmits the print data to the relay server 71 (S336). The relay server 71 transmits the print data received from the first mobile phone 10 to the MFP 51 (S286). Thereby, the relay server 71 does not need to store the print data in the storage unit 73 during the period from when the first mobile phone 10 outputs the print reservation until the relay server 71 receives the print data. It is only necessary to store the print reservation. The capacity of information used for print reservation is smaller than the capacity of print data. Therefore, it is possible to prevent a situation such as the storage capacity of the storage unit 73 of the relay server 71 being insufficient.

  In the MFP 51 described in the present application, it is possible to accept an input of the printability result by the button input unit 38 of the MFP 51 (S419). As a result, it is possible for a user in the vicinity of the MFP 51 to determine whether the MFP 51 can execute printing. A user in the vicinity of the MFP 51 can cope with the case where the MFP 51 cannot execute printing (for example, when the ink remaining in the MFP 51 is low or the print paper is out). It is appropriate to have the right to determine whether or not to execute printing.

  In the MFP 51 described in the present application, when it is determined that ink or paper may run out during printing (S432: Y, S452: Y), this is notified to the user (S434, S454). ), The reception or input of the printability result can be received (S436, S456). As a result, it is possible to perform control for accepting reception or input of a print permission result only when it is highly necessary to determine whether or not the MFP 51 can execute printing.

  In the MFP 51 described in the present application, the print data is received regardless of the setting (S414, S430, S450: YES) for receiving the print data on the condition that the “printable” printable result is accepted. Setting (S412: YES) can be selected. As a result, it is possible to increase the degree of freedom of the mode of receiving print data.

  In the MFP 51 described in the present application, the polling (S142) for acquiring print data is compared with the execution frequency of the polling (S164) for confirming whether the print reservation has been made by the first mobile phone 10 or not. The execution frequency is higher. As a result, the time required to receive the print data can be shortened without increasing the traffic to the relay server 71.

  Specific examples of the present invention have been described in detail above, but these are merely examples and do not limit the scope of the claims. The technology described in the claims includes various modifications and changes of the specific examples illustrated above. A modification will be described below.

<Modification>
The relay server 71 may transmit a print data request to the first mobile phone 10 without transmitting the print permission result to the MFP 51 in response to accepting the print permission result from the second mobile phone 9. In the case of implementing this modification, the flow may be modified so as to proceed to S266 (FIG. 3) when the printable result “printable” is received in S306 (FIG. 5). In addition, the flow (S292 to S296) for transmitting the printability result to the MFP 51 may be deleted. As a result, in response to the user of the second mobile phone 9 (an administrator of the MFP 51) permitting printing, the process of acquiring print data from the first mobile phone 10 can be executed immediately. It is possible to reduce the time required until the time.

  The first mobile phone 10 and the second mobile phone 9 may be the same terminal device. For example, the general user of the MFP 51 and the administrator are the same user. In this case, it is possible to determine whether or not the MFP 51 can execute printing using the mobile phone that has made the print reservation.

  In S417 (FIG. 9), the form in which a print permission inquiry is transmitted from the MFP 51 to the second mobile phone 9 and the form in which a print permission result is transmitted from the second mobile phone 9 to the MFP 51 are limited to the form via the relay server 71. Absent. Using the second mobile phone address registered in advance in the storage unit 33 of the MFP 51, a print permission inquiry may be sent directly from the MFP 51 to the second mobile phone 9. Further, the printability result may be directly transmitted from the second mobile phone 9 to the MFP 51. Thereby, the processing load of the relay server 71 can be reduced.

  In S419, S436, and S456, both the reception of the printability result from the second mobile phone 9 and the input of the printability result at the button input unit 38 are accepted. However, the present invention is not limited to this form. Only one of them may accept the printability result.

  A print preview instructed from the first mobile phone 10 may be confirmed by the MFP 51. In this case, the relay server 71 may transmit the print thumbnail image data together with the response information to the MFP 51 in S246. The MFP 51 may display a thumbnail image on the panel 39 based on the print thumbnail image data when displaying the confirmation screen in S416.

  In the form of displaying the preview, the first mobile phone 10 may transmit the print data itself together with the print reservation to the relay server 71 in S316 (FIG. 11). In this case, when receiving the print data in S230 (FIG. 2), the relay server 71 stores the print data in the storage unit 73. Then, print thumbnail image data is generated based on the stored print data, and after the print thumbnail image data is generated, the stored print data is erased. Thereby, since the capacity of the print thumbnail image data is smaller than that of the print data, it is possible to prevent a situation such as the storage capacity of the storage unit 73 of the relay server 71 from being insufficient.

  In S432 (FIG. 10), various methods may be used to determine whether or not ink may run out during printing by the printer 19. For example, it may be determined that there is a possibility that the ink will run out (S432: YES) when the remaining amount of ink is less than a predetermined amount that is a guideline for determining that “the amount of ink is low”. Further, it may be determined that the ink may run out when the remaining amount of ink is less than a predetermined amount that is a guideline for determining that “no ink” (S432: YES).

  In S452 (FIG. 10), the method for determining whether or not there is a possibility of running out of paper during printing by the printer 19 may be various methods. For example, when the remaining amount of paper is less than one (the remaining amount of paper is 0), it may be determined that there is a possibility that the paper will run out (S452: YES). Further, when the remaining amount of paper is less than a predetermined amount that is a guideline for determining that “the number of sheets is small”, it may be determined that there is a possibility of running out of sheets (S452: YES).

  In S246 (FIG. 3), the relay server 71 transmits information related to the reserved print data (number of pages, color print / monochrome print, etc.) to the MFP 51 together with response information indicating “print reservation is present”. It may be configured. In S166 (FIG. 8), the MFP 51 may be configured to receive information regarding reserved print data together with response information indicating “print reservation is present”. In S432 (FIG. 10), the ink type necessary for executing the print job may be specified and the ink usage amount may be calculated based on the information related to the reserved print data. Then, when the ink remaining amount of the specified ink type is smaller than the calculated ink use amount, it may be determined that there is a possibility that the ink runs out (S432: YES). In S452 (FIG. 10), the paper type (A4, B5, etc.) required for executing the print job is specified and the paper usage amount is calculated based on the information related to the reserved print data. Also good. Then, when the remaining amount of the specified sheet type is smaller than the calculated sheet use amount, it may be determined that the sheet may run out (S452: YES).

  In the present embodiment, the case has been described in which the information specifying the first mobile phone 10 (first mobile phone address) is different from the information specifying the MFP 51 (ID information and password), but is not limited to this form. . Both pieces of information may be the same information (eg, ID information and password).

  The relay server 71 can store various information in association with each other (S220 (FIG. 2)) in various forms. For example, the MFP identification information, the ID information, and the password may be stored in successive memory addresses so as to be associated with each other. Further, the memory address storing the MFP identification information and the memory address storing the ID information and the password may be stored in association with each other. Information specifying the MFP 51 (MFP identification information, ID information, password), information specifying the first mobile phone 10 (first mobile phone address), and information specifying the second mobile phone 9 (second mobile phone) The same applies to the association with (address).

  The first and second mobile phone addresses are information used to identify each of the first mobile phone 10 and the second mobile phone 9. Therefore, information that can identify the first mobile phone 10 and the second mobile phone 9 (eg, MAC address (wireless LAN), serial numbers of the first mobile phone 10 and the second mobile phone 9, the first mobile phone 10). And the second mobile phone 9 can be used instead of the first and second mobile phone addresses.

  The MFP identification information is not limited to the manufacturing serial number. Any information can be used as long as it can identify the individual MFP, and for example, a MAC address can be used.

  In S336 (FIG. 12), the transmission of print data from the first mobile phone 10 is not limited to the method using E-mail. Any communication method can be used as long as the transmission source can be specified. Further, even when a communication method in which it is difficult to specify the transmission source is used, it is possible to specify the transmission source if the information that can specify the first mobile phone 10 is transmitted together with the print data. can do.

  In S336 (FIG. 12), the form in which the print data is transmitted from the first mobile phone 10 to the relay server 71 may be various forms. For example, a configuration may be adopted in which print data is automatically returned to the relay server 71 in response to receiving a print data request from the relay server 71 in S330.

  The acquisition destination from which the relay server 71 acquires the communication destination information of the first mobile phone 10 and the second mobile phone 9 is not limited to the MFP 51, and may be each of the first mobile phone 10 and the second mobile phone 9. For example, in S218 (FIG. 2), the relay server 71 may not receive the first mobile phone address from the MFP 51. In this case, the relay server 71 stores only the received password in the storage unit 73 in S220. In step S232, the relay server 71 stores correspondence information that associates the first mobile phone address included in the print reservation received from the first mobile phone 10 with the information specifying the MFP 51 in the table storage area 12b of the storage unit 73. It may be memorized. For example, in S <b> 268, the relay server 71 may transmit the print data request to the first mobile phone 10 using the first mobile phone address included in the print reservation received from the first mobile phone 10.

  The first mobile phone 10, the second mobile phone 9, and the MFP 51 included in the printing system 1 are not limited to one, and the technology of the present application can be applied even when there are a plurality of each. Thereby, a print reservation for each of the plurality of MFPs 51 can be received from the plurality of first mobile phones 10. In addition, a print permission inquiry can be transmitted to a user (second mobile phone 9) managing each of the plurality of MFPs 51.
