  Hereinafter, a wireless network formed in accordance with a WFD procedure (for example, G / O negotiation) is referred to as “WFDNW”. At the stage where a WFDNW is newly formed by G / O negotiation, only one G / O device and one CL device belong to the WFDNW. However, the G / O device can establish a connection with another device, and can newly participate in the WFDNW as the CL device. In this case, two or more CL devices belong to the WFDNW. That is, in the WFDNW, there can be one G / O device and one or more CL devices. The G / O device manages one or more CL devices. Specifically, the G / O device registers the MAC addresses of one or more CL devices in the management list in the memory of the G / O device. The G / O device can execute wireless communication of the target data with the CL device registered in the management list without using other devices. The G / O device can relay wireless communication of target data (for example, print data, scan data, etc.) between a plurality of CL devices. In other words, the pair of CL devices can perform wireless communication of the target data via the G / O device.

  FIG. 2 shows an example of a WFDNW in which the PC 110 is a G / O device and the portable terminal 50 and the MFP 100 are CL devices. In a state where such a WFDNW is formed, the wireless LAN I / F 20 of the MFP 10 that is the CL device is a G / O device from the wireless LAN I / F 60 of the portable terminal 50 that is the CL device using the WFDNW. Print data can be received via the PC 110.

  FIG. 2 further shows an example of a WFDNW in which the MFP 10 is a G / O device and the portable terminal 50 is a CL device. In a state in which such a WFDNW is formed, the wireless LAN I / F 20 of the MFP 10 that is the G / O device uses the WFDNW to communicate from the wireless LAN I / F 60 of the portable terminal 50 that is the CL device via another device. Without receiving print data.

  Each of MFP 10 and portable terminal 50 stores WSI for belonging to WFDNW (that is, WSI for executing WFD communication (hereinafter referred to as “WFDWSI”)). WFD WSI includes an SSID, BSSID, authentication method, encryption method, password, and the like. The SSID is identification information for identifying the WFDNW, and is generated by the G / O device. The BSSID is identification information for identifying the G / O device (that is, the MAC address of the G / O device). The WFD WSI of the MFP 10 further includes the IP address of the MFP 10, and the WFD WSI of the portable terminal 50 further includes the IP address of the portable terminal 50. In WFD printing, the MFP 10 and the portable terminal 50 execute print data communication using, for example, an LPR communication protocol.

(BT printing)
In BT printing, print data communication is executed using a BTNW formed according to the BT method. FIG. 2 shows a BTNW including the MFP 10 and the portable terminal 50. In a state in which such a BTNW is formed, the BTI / F 24 of the MFP 10 can receive print data from the BTI / F 64 of the portable terminal 50 without using other devices using the BTNW.

  Each of MFP 10 and portable terminal 50 stores WSI for belonging to BTNW (that is, WSI for executing BT communication (hereinafter referred to as “BTWSI”)). The BTWSI includes a PIN code (ie, a pairing code). In the BT printing, the MFP 10 and the portable terminal 50 use a communication protocol such as BPP (abbreviation of Basic Printing Profile), BIP (abbreviation of Basic Imaging Profile), OPP (abbreviation of Object Push Profile), for example. Execute print data communication.

(EP)
In EP, transmission of print data from the portable terminal 50 to the MFP 10 (that is, e-mail communication) is executed via the Internet. As shown in FIG. 2, the wireless LAN I / F 20 of the MFP 10 can receive print data from the wireless LAN I / F 60 of the portable terminal 50 via the mail server 120.

  In order to execute e-mail communication of print data, each of the MFP 10 and the portable terminal 50 stores ESI. That is, the portable terminal 50 stores at least ESI for transmission (that is, SMTP setting information) for transmitting e-mail. The MFP 10 stores at least reception ESI (that is, POP setting information) for receiving e-mail.

  The SMTP setting information includes an SMTP server URL (abbreviation of Uniform Resource Locator), a user name, a password, and the like. The POP setting information includes a POP server URL, a user name, a password, and the like. In this embodiment, the SMTP server and the POP server are shown as one mail server 120. However, in the modification, they may be configured separately. In EP, the MFP 10 and the portable terminal 50 execute print data communication using SMTP and POP communication protocols.

(CP)
In the CP, transmission of print data from the portable terminal 50 to the MFP 10 (that is, cloud communication) is executed via the Internet. As shown in FIG. 2, the wireless LAN I / F 20 of the MFP 10 can receive print data from the wireless LAN I / F 60 of the portable terminal 50 via the print CL server 140.

  In order to execute cloud communication of print data, each of the MFP 10 and the portable terminal 50 stores a print CSI. The print CSI includes the URL (abbreviation of Uniform Resource Locator) of the print CL server 140, account information, authentication information (for example, access token), and the like. In CP, the MFP 10 and the portable terminal 50 execute print data communication using, for example, an HTTP (abbreviation of Hyper Text Transfer Protocol) communication protocol.

  The DP, EP, and CP are printing functions that can be executed by the MFP 10, respectively. In other words, the DP, EP, and CP mean communication methods for the MFP 10 to receive print data. That is, DP means a communication method called a direct method (that is, a normal Wi-Fi method, a WFD method, and a BT method). EP and CP mean communication methods such as an e-mail method and a cloud method, respectively. In other words, the MFP 10 can receive print data using any one of the three communication methods of the direct method, the e-mail method, and the cloud method.

(Application processing of portable terminal 50; FIG. 3)
Next, with reference to FIG. 3, the content of processing realized by the MFP application installed in the portable terminal 50 will be described. When the user of the portable terminal 50 desires the MFP 10 to execute printing, the user operates the operation key 52 to activate the MFP application. Next, the user brings the portable terminal 50 closer to the MFP 10 in order to establish an NFC connection between the MFP 10 and the portable terminal 50.

  When the distance between the portable terminal 50 and the MFP 10 becomes smaller than a distance (for example, 10 cm) at which NFC communication can be performed, an NFC connection is established between the MFP 10 and the portable terminal 50. In this case, in S10, the CPU 72 transmits a function request to the MFP 10 via the NFC I / F 62 using the NFC connection. The function request is a request for causing the MFP 10 to transmit response data (see S100 and S102 in FIG. 7) described later.

  In S <b> 12, the CPU 72 receives response data from the MFP 10 via the NFC I / F 62 using the NFC connection. The response data includes information indicating DPOK when the MFP 10 can execute DP, and includes information indicating DPNG when the MFP 10 cannot execute DP. The response data includes information indicating EPOK when the MFP 10 can execute EP, and includes information indicating EPNG when the MFP 10 cannot execute EP. The response data includes information indicating CPOK when the MFP 10 can execute CP, and includes information indicating CPNG when the MFP 10 cannot execute CP. If the MFP 10 belongs to a wireless LAN (normal WI-FiNW or WFDNW), the response data further includes the SSID and BSSID of the wireless LAN.

  In S30, the CPU 72 executes a function selection process. As will be described in detail later, in the function selection process (FIGS. 4 to 6), the CPU 72 selects one communication method from one or more communication methods (DP, EP, CP) that the MFP 10 can execute. To do.

  Next, in S <b> 50, the CPU 72 transmits the selection result of the function selection process in S <b> 30 (that is, DP, EP, or CP) to the MFP 10 through the NFC I / F 62 using the NFC connection.

  Subsequently, in S52, the CPU 72 receives transmission destination information from the MFP 10 via the NFC I / F 62 using the NFC connection. The transmission destination information indicates a transmission destination for executing transmission of print data from the portable terminal 50 to the MFP 10 in accordance with the communication method corresponding to the selection result of the function selection process in S30. As will be described in detail later, when the selection result is EP, the destination information includes the email address of the MFP 10 (see S119 in FIG. 11). If the selection result is CP, the destination information includes the CSI for printing (that is, the URL of the print CL server 140, etc.) stored in the memory 34 of the MFP 10 (see S120 in FIG. 11).

  When the selection result is DP, the destination information is at least one WSI of each WSI (that is, normal Wi-Fi WSI, WFD WSI, and BTWSI) stored in the memory 34 of the MFP 10. (See S113, S115, and S117 in FIG. 11). More specifically, when the MFP 10 can execute normal Wi-Fi printing, the transmission destination information includes information included in the normal Wi-Fi WSI of the MFP 10 (normal Wi-Fi SSID, normal Wi-Fi). FI BSSID and normal Wi-Fi IP address of MFP 10) (see S113 in FIG. 11). When the MFP 10 can execute WFD printing, the transmission destination information includes information (SFD for WFD, BSSID for WFD, and IP address for WFD of the MFP 10) included in the WFD WSI of the MFP 10 (FIG. 11 (see S115). When the MFP 10 is a G / O device, the transmission destination information further includes a password included in the WFD WSI of the MFP 10. However, when the MFP 10 is a CL device, the transmission destination information does not include the password included in the WFD WSI of the MFP 10. When the MFP 10 can execute BT printing, the transmission destination information includes the BTWSI (that is, the PIN code) of the MFP 10 (see S117 in FIG. 11).

  As described above, in this embodiment, the CPU 72 performs one round-trip communication of function request transmission (S10) and reception of response data such as DPOK (S12), selection result transmission (S50), and transmission destination information. Two-way communication including the one-way communication called reception (S52) is executed. That is, the CPU 72 performs two round-trip communications in one NFC connection. When S52 ends, the NFC connection is disconnected.

  Next, in S54, the CPU 72 uses the transmission destination information received in S52 to transmit the print data to the MFP 10 according to the communication method corresponding to the selection result of the function selection process in S30.

  Specifically, for example, when the selection result is EP, the CPU 72 generates an email in which the email address of the MFP 10 included in the destination information is specified as the destination address, and the email is included in the email. Print data (that is, data to be printed designated by the user) is attached. Then, the CPU 72 transmits an e-mail via the wireless LAN I / F 60 or the cellular NWI / F 66.

  When the mobile terminal 50 belongs to a wireless LAN (that is, normal Wi-Fi NW or WFDNW), the CPU 72 transmits an e-mail via the wireless LAN I / F 60. Thereby, the portable terminal 50 can transmit print data to the MFP 10 via the wireless LAN and the Internet (that is, the mail server 120) (see EP in FIG. 2). Further, when the mobile terminal 50 belongs to the cellular NW, the CPU 72 transmits an e-mail via the cellular NWI / F 66. Thereby, the portable terminal 50 can transmit print data to the MFP 10 via the cellular network and the Internet (that is, the mail server 120) (see EP in FIG. 2).

  In addition, when the mobile terminal 50 belongs to both the wireless LAN and the cellular network, the CPU 72 transmits an e-mail via the wireless LAN I / F 60. That is, the CPU 72 transmits an e-mail using the wireless LAN preferentially. The reason for this is as follows. That is, the cellular communication using the cellular network may be subject to a charge based on the data size of the communication data, but the normal Wi-Fi communication (or WFD communication) using the wireless LAN is normally , It is not subject to metered billing. For this purpose, the CPU 72 transmits an email using the wireless LAN preferentially.

  For example, when the selection result is CP, the CPU 72 connects to the print CL server 140 via the wireless LAN I / F 60 or the cellular NWI / F 66 using the print CSI included in the destination information. To do. Next, the CPU 72 generates a command in which the URL of the print CL server 140 included in the print CSI is specified as a transmission destination, and attaches the print data to the command. Then, the CPU 72 transmits a command including print data via the wireless LAN I / F 60 or the cellular NWI / F 66. Note that which of the wireless LAN I / F 60 and the cellular NWI / F 66 is used is the same as in the case of EP. The portable terminal 50 can transmit print data to the MFP 10 via the wireless LAN or cellular NW and the Internet (that is, the print CL server 140) (see CP in FIG. 2).

  For example, when the selection result is DP, the CPU 72 first determines whether the MFP 10 and the portable terminal 50 belong to the same NW using the transmission destination information. For example, when the set of the normal Wi-Fi SSID and the normal Wi-Fi BSSID of the MFP 10 matches the set of the normal Wi-Fi SSID and the normal Wi-Fi BSSID of the mobile terminal 50, the CPU 72 Determines that the MFP 10 and the portable terminal 50 belong to the same normal Wi-Fi NW. For example, when the set of the WFD SSID and WFD BSSID of the MFP 10 and the set of the WFD SSID and WFD BSSID of the portable terminal 50 match, the CPU 72 determines that the MFP 10 and the portable terminal 50 are the same. It is determined that the user belongs to the WFDNW. Further, for example, when the PIN code included in the BTWSI of the MFP 10 matches the PIN code included in the BTWSI of the portable terminal 50, the CPU 72 indicates that the MFP 10 and the portable terminal 50 belong to the same BTNW. Judge.

  In this embodiment, the CPU 72 determines whether the MFP 10 and the portable terminal 50 belong to the same NW (normal Wi-Fi NW or WFDNW) by executing a match determination of the SSID and BSSID set. to decide. On the other hand, in the modification, the CPU 72 may determine whether the MFP 10 and the portable terminal 50 belong to the same NW by executing only the SSID match determination, or the BSSID match. It may be determined whether the MFP 10 and the portable terminal 50 belong to the same NW by executing only the determination.

  If the CPU 72 determines that the MFP 10 and the portable terminal 50 belong to the same NW, the CPU 72 transmits print data to the MFP 10 using the same NW. For example, if the same NW is the normal Wi-Fi NW, the CPU 72 prints via the wireless LAN I / F 60 with the normal Wi-Fi IP address of the MFP 10 included in the destination information as the destination. Send data. Accordingly, the portable terminal 50 can transmit print data to the MFP 10 via the AP 100 (see normal Wi-Fi printing in FIG. 2).

  Further, for example, when the same NW is the WFDNW, the CPU 72 transmits print data via the wireless LAN I / F 60 with the WFD IP address of the MFP 10 included in the transmission destination information as the transmission destination. . Accordingly, the portable terminal 50 can transmit print data to the MFP 10 via the PC 110 that is a G / O device or without using other devices (see WFD printing in FIG. 2).

  Further, for example, when the same NW is the BTNW, the CPU 72 uses the PIN code included in the BTWSI of the MFP 10 (that is, the BTWSI of the portable terminal 50) to print data via the BTI / F64. Send. Thereby, the portable terminal 50 can transmit print data to the MFP 10 without using other devices (see BT printing in FIG. 2).

  As described above, in S54, when the selection result is DP and the MFP 10 and the portable terminal 50 belong to the same NW, the portable terminal 50 preferentially uses the same NW. The print data is transmitted to the MFP 10. Thereby, since the portable terminal 50 does not need to establish a wireless connection with the MFP 10, print data can be quickly transmitted to the MFP 10.

  When the MFP 10 and the portable terminal 50 belong to two or more identical NWs, the CPU 72 preferentially uses an NW having a high communication speed. For example, when the MFP 10 and the portable terminal 50 belong to the same WFDNW and the same BTNW, the CPU 72 transmits print data to the MFP 10 using the WFDNW.

  If the CPU 72 determines that the MFP 10 and the portable terminal 50 do not belong to the same NW, the CPU 72 executes the following processing. As described above, the transmission destination information does not include the password used in the normal Wi-Fi NW to which the MFP 10 belongs (see S113 in FIG. 11). Therefore, the CPU 72 cannot allow the mobile terminal 50 to participate in the normal Wi-Fi NW.

  The destination information may include information (WFD SSID, WFD BSSID, password, and WFD IP address of the MFP 10) used in the WFDNW in which the MFP 10 is a G / O device (see S115 in FIG. 11). ). In this case, the CPU 72 establishes a wireless connection with the MFP 10 that is a G / O device using the information. Accordingly, the CPU 72 can cause the mobile terminal 50 to participate as a CL device in the WFDNW in which the MFP 10 is a G / O device. Then, the CPU 72 transmits print data via the wireless LAN I / F 60 using the WFD IP address of the MFP 10 included in the transmission destination information as a transmission destination. Accordingly, the portable terminal 50 that is a CL device can transmit print data to the MFP 10 that is a G / O device by using WFDNW without using other devices.

  Further, the destination information may include BTWSI (that is, a PIN code) of the MFP 10 (see S117 in FIG. 11). In this case, the CPU 72 establishes a wireless connection with the MFP 10 using BTWSI. Then, the CPU 72 transmits print data via the BTI / F 64 using the PIN code. Accordingly, the portable terminal 50 can transmit print data to the MFP 10 using BTNW without using other devices.

  When the destination information includes both information used in the WFDNW in which the MFP 10 is a G / O device and the BTWSI of the MFP 10, the CPU 72 preferentially selects a WFDNW having a high communication speed. The MFP 10 decides to use the mobile terminal 50 as a CL device in the WFDNW, which is a G / O device.

(Function selection processing; FIG. 4)
Next, the function selection process in S30 of FIG. 3 will be described with reference to FIG. In S31, the CPU 72 determines whether the MFP 10 and the portable terminal 50 belong to the same normal Wi-Fi NW or the same WFDNW. If neither the normal Wi-Fi WSI nor the WFD WSI of the mobile terminal 50 is stored in the memory 74, the CPU 72 determines NO in S31 and proceeds to S33.

  When the normal Wi-Fi WSI of the mobile terminal 50 is stored in the memory 74, the CPU 72 matches the set of the normal Wi-Fi SSID and the normal Wi-Fi BSSID included in the normal Wi-Fi WSI. And whether or not a set of BSSIDs (hereinafter referred to as “first set”) is included in the response data. If the first set is included in the response data, the CPU 72 determines YES in S31, and proceeds to S32. If the first set is not included in the response data, the CPU 72 determines NO in S31. Judge and proceed to S33.

  In addition, when the WFD WSI of the portable terminal 50 is stored in the memory 74, the CPU 72 sets the SSID and BSSID that match the set of the WFD SSID and WSID BSSID of the WFD WSI (hereinafter referred to as “second set”). ") Is included in the response data. If the second set is included in the response data, the CPU 72 determines YES in S31, and proceeds to S32. If the second set is not included in the response data, the CPU 72 determines NO in S31. Judge and proceed to S33.

  As described above, when YES is determined in S31, the response data includes at least one of the first set and the second set. In such a situation, since the MFP 10 can execute at least one of normal Wi-Fi printing and WFD printing (see S72 and S75 in FIG. 8 described later), response data including DPOK is sent to the portable terminal 50. Send. In this case, the response data includes OK or NG for each of EP and CP. In S32, the CPU 72 selects a DP from one or more communication methods (at least a DP) indicating OK included in the response data, and ends the function selection process. In this case, since the MFP 10 and the portable terminal 50 belong to the same normal Wi-Fi NW or the same WFDNW, in S54 of FIG. 3, the CPU 72 uses the same NW (that is, according to DP) to perform printing. Data can be transmitted to the MFP 10.

  In S33, the CPU 72 determines whether or not the portable terminal 50 belongs to a wireless LAN (that is, normal Wi-Fi NW, WFDNW). When at least one of the normal Wi-Fi WSI and WFD WSI is stored in the memory 74, the CPU 72 determines YES in S33, proceeds to S34, and both the normal Wi-Fi WSI and WFD WSI are stored in the memory 74. If not stored, NO is determined in S33, and the process proceeds to S38.

  In S <b> 34, the CPU 72 determines whether the mobile terminal 50 can execute Internet communication via the wireless LAN. Specifically, the CPU 72 determines whether or not the portable terminal 50 can communicate with the confirmation server 130 on the Internet. That is, the CPU 72 monitors the reception of a response signal from the confirmation server 130 by transmitting a signal via the wireless LAN I / F 60 with the URL of the confirmation server 130 stored in advance in the memory 34 as a transmission destination. When a response signal is received from the confirmation server 130, the CPU 72 determines YES in S34 and proceeds to S150. In this case, the portable terminal 50 can execute Internet communication via the wireless LAN. On the other hand, when the response signal is not received from the confirmation server 130, the CPU 72 determines NO in S34 and proceeds to S35.

(First selection process; FIG. 5)
In S150, the CPU 72 executes a first selection process (see FIG. 5). In S151, the CPU 72 determines whether or not information indicating CPOK is included in the response data. If the response data includes information indicating CPOK, the CPU 72 determines YES in S151, selects a CP in S152, and ends the first selection process.

  When information indicating CPNG is included in the response data, the CPU 72 determines NO in S151, and determines whether information indicating EPOK is included in the response data in S153. If the information indicating EPOK is included in the response data, the CPU 72 determines YES in S153, selects EP in S154, and ends the first selection process.

  When the information indicating EPNG is included in the response data, the CPU 72 determines NO in S153, and determines whether or not the information indicating DPOK is included in the response data in S155. If the information indicating DPOK is included in the response data, the CPU 72 determines YES in S155, selects the DP in S156, and ends the first selection process.

  On the other hand, when information indicating DPNG is included in the response data, the CPU 72 determines NO in S155, and displays an error screen on the display mechanism 54 indicating that the MFP 10 cannot execute printing in S157. To end the first selection process. In addition, when S157 is performed, the process after S50 of FIG. 3 is not performed.

  The first selection process is executed in a situation where the mobile terminal 50 belongs to a wireless LAN (that is, normal Wi-Fi NW, WFDNW) (YES in S33 of FIG. 4). And the priority order of selection of the communication method is the order of CP, EP, DP (see FIG. 5). The reason why the CP and EP that use the Internet are given priority over the DP that does not use the Internet is as follows.

  That is, since the portable terminal 50 and the MFP 10 do not belong to the same NW (NO in S31), the portable terminal 50 establishes a wireless connection between the portable terminal 50 and the MFP 10 in order to use direct communication. Processing must be performed. On the other hand, since the mobile terminal 50 uses cloud communication or e-mail communication, it is not necessary to establish the wireless connection. Thus, CP and EP are prioritized from the viewpoint of reducing the processing load. Moreover, since the portable terminal 50 belongs to the wireless LAN, when CP or EP is selected, the portable terminal 50 prints using the wireless LAN instead of the cellular network in S54 of FIG. Data is transmitted to the MFP 10. For this reason, even if CP or EP is selected, the communication of the print data is not subject to metered charging. Thus, from the viewpoint of accounting, there is no problem even if CP and EP are prioritized.

  The reason why the CP is given priority over the EP is that, for example, the cloud communication may normally be superior in terms of security compared to the email communication. When completing the first selection process, the CPU 72 ends the function selection process.

  In S35 of FIG. 4, the CPU 72 determines whether or not the information indicating DPOK is included in the response data. If the response data includes information indicating DPOK, the CPU 72 determines YES in S35, selects DP in S36, and ends the function selection process. If the mobile terminal 50 belongs to a wireless LAN but cannot perform Internet communication via the wireless LAN (NO in S34), cloud communication and e-mail communication are performed via the wireless LAN. Infeasible. Therefore, in S35 and S36, the CPU 72 selects DP when information indicating DPOK is included in the response data without selecting CP and EP. On the other hand, when information indicating DPNG is included in the response data, the CPU 72 determines NO in S35, and proceeds to S38. However, in a modified example, when it is determined NO in S34, S35 may be skipped and the process may proceed to S38.

  In S38, the CPU 72 determines whether or not the portable terminal 50 belongs to the cellular NW. If the portable terminal 50 belongs to the cellular network, the CPU 72 determines YES in S38 and proceeds to S160. On the other hand, if the portable terminal 50 does not belong to the cellular NW, NO is determined in S38, and the process proceeds to S39.

(Second selection process; FIG. 6)
In S160, the CPU 72 executes a second selection process (see FIG. 6). In the second selection process, the order of each process is different from that in the first selection process (FIG. 5). That is, in the first selection process, the priority order is the order of CP, EP, and DP, but in the second selection process, the priority order is the order of DP, CP, and EP. S161 and 162 are the same as S155 and 156 of FIG. S163 and 164 are the same as S151 and 152 of FIG. 5, and S165 and 166 are the same as S153 and 154 of FIG. S167 is the same as S157 of FIG.

  In the second selection process, the mobile terminal 50 does not belong to the wireless LAN (that is, normal Wi-FiNW, WFDNW) (NO in S33 in FIG. 4), or the mobile terminal 50 passes through the wireless LAN. The communication is executed in a state where the user belongs to the cellular network NW in either state where Internet communication is not executable (NO in S34 of FIG. 4) (YES in S38 of FIG. 4). And the priority order of selection of a communication system is the order of DP, CP, EP (see FIG. 6). The reason why the DP that does not use the Internet is given priority over the CP and EP that use the Internet is as follows.

  That is, since the mobile terminal 50 cannot perform Internet communication via the wireless LAN and belongs to the cellular network NW, when the CP or EP is selected, the mobile terminal 50 is selected in S54 of FIG. Transmits the print data to the MFP 10 using the cellular network. For this reason, when CP or EP is selected, communication of print data can be subject to metered charging. On the other hand, when DP is selected, the portable terminal 50 newly establishes a wireless connection with the MFP 10 and transmits print data to the MFP 10 using the wireless LAN in S54 of FIG. In this case, since the cellular network is not used, print data communication is not subject to metered charging. Thus, DP is prioritized from the viewpoint of billing.

  S39 and S40 are the same as S35 and 36, respectively. That is, since the portable terminal 50 cannot execute Internet communication via the wireless LAN or the cellular network, the CPU 72 does not select CP and EP, and information indicating DPOK is included in the response data. Select DP. However, if information indicating DPNG is included in the response data, the CPU 72 determines NO in S39, and causes the display mechanism 54 to display an error screen indicating that the MFP 10 cannot execute printing in S41. . In addition, when S41 is performed, the process after S50 of FIG. 3 is not performed.

(Processing of MFP 10; FIG. 7)
Next, the contents of processing executed by the MFP 10 will be described with reference to FIG. The process of FIG. 7 is triggered by the establishment of an NFC connection between the MFP 10 and the portable terminal 50 as a trigger.

  In S60, the CPU 32 receives a function request (see S10 in FIG. 3) from the portable terminal 50 via the NFC I / F 22. Next, in S70, S80, and S90, the CPU 32 executes DP function confirmation processing (see FIG. 8), EP function confirmation processing (see FIG. 9), and CP function confirmation processing (see FIG. 10). In these processes, the CPU 32 specifies which printing function of the DP, EP, and CP can be executed by the MFP 10. Details of these processes will be described later.

  Next, in S100, the CPU 32 generates response data using the confirmation results in S70 to S90. As will be described later in detail, in S70, information indicating OK or NG is stored in the memory 34 for each of normal Wi-Fi printing, WFD printing, and BT printing. In S100, the CPU 32, when information indicating OK is stored in the memory 34 for at least one of normal Wi-Fi printing, WFD printing, and BT printing, a response including information indicating DPOK. Generate data. In addition, when information indicating NG is stored in the memory 34 for all of normal Wi-Fi printing, WFD printing, and BT printing, the CPU 32 generates response data including information indicating DPNG. To do.

  As will be described in detail later, in S80, information indicating EPOK or EPNG is stored in the memory 34, and in S90, information indicating CPOK or CPNG is stored in the memory 34. In S100, when information indicating EPOK (or CPOK) is stored in the memory 34, the CPU 32 generates response data including information indicating EPOK (or CPOK), and indicates EPNG (or CPNG). Is stored in the memory 34, response data including information indicating EPNG (or CPNG) is generated.

  When the MFP 10 belongs to the normal Wi-Fi NW (that is, when the normal Wi-Fi printing is OK), in S100, the CPU 32 causes the normal Wi-Fi WSI included in the memory 34 to include the normal Wi-Fi WSI. Response data including a set of SSID for Fi and BSSID for normal Wi-Fi is generated. When the MFP 10 belongs to the WFDNW (that is, when the WFD printing is OK), in S100, the CPU 32 responds including a set of the SFD for WFD and the BSSID for WFD included in the WFD WSI in the memory 34. Generate data.

  In S <b> 102, the CPU 32 transmits response data to the portable terminal 50 via the NFC I / F 22. Accordingly, the portable terminal 50 can select a communication method for executing transmission of print data from the portable terminal 50 to the MFP 10 using the response data (S12 and S30 in FIG. 3).

(DP function confirmation processing; FIG. 8)
With reference to FIG. 8, the DP function confirmation processing in S70 of FIG. 7 will be described. In S <b> 71, the CPU 32 determines whether or not the MFP 10 has a normal Wi-Fi function (that is, whether or not the MFP 10 includes a wireless LAN I / F 20). When the MFP 10 has the normal Wi-Fi function, the CPU 32 determines YES in S71, and stores information indicating normal Wi-Fi printing OK in the memory 34 in S72. When S72 ends, the process proceeds to S74.

  On the other hand, when the MFP 10 does not have the normal Wi-Fi function, the CPU 32 determines NO in S71, and in S73, information indicating normal Wi-Fi printing NG, information indicating WFD printing NG, Is stored in the memory 34. WFD wireless communication is wireless communication based on normal Wi-Fi wireless communication. Accordingly, when the MFP 10 does not have the normal Wi-Fi function (NO in S71), the MFP 10 does not have the WFD function (that is, the program for executing the WFD communication is not stored in the memory 34). ). Accordingly, in S73, not only information indicating normal Wi-Fi printing NG but also information indicating WFD printing NG is stored in the memory 34. When S73 ends, the process proceeds to S77.

  In S74, the CPU 32 determines whether or not the MFP 10 has a WFD function (that is, whether or not a program for executing WFD communication is stored in the memory 34). If the MFP 10 has a WFD function, the CPU 32 determines YES in S74, and stores information indicating WFD printing OK in the memory 34 in S75. On the other hand, if the MFP 10 does not have the WFD function, the CPU 32 determines NO in S74, and stores information indicating the WFD printing NG in the memory 34 in S76. When S75 or S76 is completed, the process proceeds to S77.

  In S77, the CPU 32 determines whether or not the MFP 10 has the BT function (that is, whether or not the MFP 10 includes the BTI / F 24). If the MFP 10 has the BT function, the CPU 32 determines YES in S77, and stores information indicating BT printing OK in the memory 34 in S78. On the other hand, if the MFP 10 does not have a BT function, the CPU 32 determines NO in S77, and stores information indicating BT printing NG in the memory 34 in S79.

(EP function confirmation processing; FIG. 9)
With reference to FIG. 9, the EP function confirmation processing in S80 of FIG. 7 will be described. In S81, the CPU 32 determines whether or not the MFP 10 has an EP function (that is, whether or not a program for receiving an e-mail and executing printing in accordance with print data included in the e-mail is stored in the memory 34). Or). If the MFP 10 has the EP function, the CPU 32 determines YES in S81, and proceeds to S82. On the other hand, if the MFP 10 does not have an EP function, the CPU 32 determines NO in S81, and stores information indicating EPNG in the memory 34 in S84.

  In S <b> 82, the CPU 32 determines whether or not reception ESI (that is, POP setting information) that is ESI for the MFP 10 to receive an e-mail is stored in the memory 34. If the reception ESI is stored in the memory 34, the CPU 32 determines YES in S82, and stores information indicating EPOK in the memory 34 in S83. On the other hand, if the reception ESI is not stored in the memory 34, the CPU 32 determines NO in S82, and stores information indicating EPNG in the memory 34 in S84.

(CP function confirmation processing; FIG. 10)
With reference to FIG. 10, the CP function confirmation processing in S90 of FIG. 7 will be described. In S <b> 91, the CPU 32 determines whether or not the MFP 10 has a CP function (that is, whether or not a program for executing cloud communication with the print CL server 140 is stored in the memory 34). If the MFP 10 has the CP function, the CPU 32 determines YES in S91 and proceeds to S92. On the other hand, if the MFP 10 does not have the CP function, the CPU 32 determines NO in S91, and stores information indicating CPNG in the memory 34 in S95.

  In S <b> 92, the CPU 32 stores in the memory 34 printing CSI (that is, the URL, account information, authentication information, etc. of the print CL server 140) that is CSI for the MFP 10 to use the print CL server 140. Judge whether or not. If the printing CSI is stored in the memory 34, the CPU 32 determines YES in S92, and proceeds to S93. On the other hand, when the CSI for printing is not stored in the memory 34, the CPU 32 determines NO in S92, and stores information indicating CPNG in the memory 34 in S95.

  In S93, the CPU 32 determines whether the MFP 10 can communicate with the confirmation server 130 on the Internet. More specifically, the CPU 32 transmits a signal with the URL of the confirmation server 130 stored in advance in the memory 34 as a transmission destination and monitors whether a response signal is received from the confirmation server 130. When a response signal is received from the confirmation server 130, the CPU 32 determines YES in S93, and stores information indicating CPOK in the memory 34 in S94. On the other hand, when a response signal is not received from the confirmation server 130, the CPU 32 determines NO in S93, and stores information indicating CPNG in the memory 34 in S95. Note that, for example, if a contract with a provider for Internet communication is not made, or if a gateway for Internet communication is not functioning, NO can be determined in S93.

  When S102 in FIG. 7 is finished, in S104, the CPU 32 receives the selection result (that is, DP, EP, or CP) from the portable terminal 50 via the NFC I / F 22. Next, in S110, the CPU 32 executes transmission destination information preparation processing.

(Destination information preparation process; FIG. 11)
With reference to FIG. 11, the contents of the destination information preparation process of S110 of FIG. 7 will be described. In S111, the CPU 32 determines whether or not the selection result is DP. If the selection result is DP, the CPU 32 determines YES in S111 and proceeds to S112. On the other hand, if the selection result is EP or CP, NO is determined in S111, and the process proceeds to S118.

  In S112, the CPU 32 determines whether information indicating normal Wi-Fi printing OK is stored in the memory 34 in S70 of FIG. 7 (see FIG. 8). If the information indicating normal Wi-Fi printing OK is stored in the memory 34, the CPU 32 determines YES in S112, and proceeds to S113. On the other hand, when information indicating normal Wi-Fi printing NG is stored in the memory 34, the CPU 32 determines NO in S112, and proceeds to S116.

  In S113, the CPU 32 identifies each information (normal Wi-Fi SSID, normal Wi-Fi BSSID, and normal Wi-Fi IP address of the MFP 10) included in the normal Wi-Fi WSI of the MFP 10 from the memory 34. To prepare the information as transmission destination information. In this embodiment, in the normal Wi-Fi NW, the AP 100 has the authority to allow other devices to participate in the normal Wi-Fi NW. However, a device (for example, the MFP 10) different from the AP 100 has another device in the normal Wi-Fi NW. Adopts a security policy that does not have the authority to participate. Therefore, in S113, the CPU 32 does not prepare a password included in the normal Wi-Fi WSI of the MFP 10 (that is, does not transmit a password as transmission destination information). However, in a modified example, the CPU 32 may prepare a password (that is, the password may be transmitted as transmission destination information).

  Next, in S114, the CPU 32 determines whether or not the information indicating the WFD printing OK is stored in the memory 34 in S70 of FIG. 7 (see FIG. 8). If the information indicating WFD printing OK is stored in the memory 34, the CPU 32 determines YES in S114, and proceeds to S115. On the other hand, if the information indicating WFD printing NG is stored in the memory 34, the CPU 32 determines NO in S114, and proceeds to S116.

  In S115, the CPU 32 executes the following processes according to the current state (G / O state, CL state, or device state) of the MFP 10. When the current state of the MFP 10 is the G / O state, the CPU 32 stores each information (SFD for WFD, BSSID for WFD, IP address for WFD of the MFP 10 and password) included in the WFD WSI of the MFP 10 in the memory. By specifying from 34, such information is prepared as transmission destination information. Further, when the current state of the MFP 10 is the CL state, the CPU 32 stores information (SFD for WFD, BSSID for WFD, and IP address for WFD of the MFP 10) included in the WFD WSI of the MFP 10 from the memory 34. By specifying, such information is prepared as transmission destination information.

  In this embodiment, in the WFDNW, the G / O device has the authority to join other devices to the WFDNW, but the CL device adopts a security policy that does not have the right to join other devices to the WFDNW. doing. Accordingly, the CPU 32 prepares a password when the current state of the MFP 10 is the G / O state, but does not prepare a password when the current state of the MFP 10 is the CL state (that is, the transmission destination). Do not send passwords as information). However, in a modification, the CPU 32 may prepare a password when the current state of the MFP 10 is the CL state (that is, the password may be transmitted as transmission destination information).

  When the current state of the MFP 10 is the device state, the CPU 32 shifts the state of the MFP 10 to the G / O state. Here, the CPU 32 voluntarily shifts the state of the MFP 10 to the G / O state without executing the G / O negotiation. Next, the CPU 32 further generates the WFD WSI of the MFP 10 (that is, the WFD SSID, the WFD BSSID, the authentication method, the encryption method, the password, and the WFD IP address) in the memory 34. The CPU 32 further generates a management list in the memory 34 in which the MAC address of the CL device is to be described. At this stage, no MAC address is described in the management list. That is, the CPU 32 forms a WFDNW to which only the MFP 10 that is a G / O device belongs. Then, the CPU 32 identifies each information (SFD for WFD, BSSID for WFD, IP address for WFD of MFP 10 and password) included in the WFD WSI of the MFP 10 from the memory 34, and sends the information to the destination information. Prepare as.

  In S116, the MFP 10 determines whether or not information indicating BT printing OK is stored in the memory 34 in S70 of FIG. 7 (see FIG. 8). When the information indicating BT printing OK is stored in the memory 34, the CPU 32 determines YES in S116, and proceeds to S117. On the other hand, when information indicating BT printing NG is stored in the memory 34, the CPU 32 determines NO in S116 and ends the transmission destination information preparation process.

  In S117, when the MFP 10 currently belongs to the BTNW (that is, when the MFP 10 has established a BT connection with another device), the CPU 32 specifies the BTWSI of the MFP 10 by identifying the BTWSI of the MFP 10 from the memory 34. Is prepared as destination information. Further, the CPU 32 generates a new BTWSI in the memory 34 when the MFP 10 does not currently belong to the BTNW. Then, the CPU 32 specifies the BTWSI of the MFP 10 as the transmission destination information by specifying the BTWSI of the MFP 10 from the memory 34.

  In S118, the CPU 32 determines whether or not the selection result is EP. If the selection result is EP, the CPU 32 determines YES in S118 and proceeds to S119. On the other hand, if the selection result is CP, the CPU 32 determines NO in S118 and proceeds to S120.

  In S <b> 119, the CPU 32 prepares the e-mail address of the MFP 10 as transmission destination information by specifying a predetermined e-mail address of the MFP 10 from the memory 34. When S119 ends, the destination information preparation process ends.

  In S120, the CPU 32 specifies the printing CSI from the memory 34, thereby preparing the printing CSI as transmission destination information. When S120 ends, the destination information preparation process ends.

  When S110 of FIG. 7 is finished, in S130, the CPU 32 transmits the transmission destination information to the portable terminal 50 via the NFC I / F 22. Thereby, the portable terminal 50 can transmit the print data to the MFP 10 using the transmission destination information (S54 in FIG. 3).

  In S132, the CPU 32 receives print data from the portable terminal 50 according to the communication method (that is, the direct method, the e-mail method, or the cloud method) indicated by the selection result received in S104. For example, if the selection result is EP, the CPU 32 includes print data from the mail server 120 via the wireless LAN I / F 20 or other I / F (for example, wired communication I / F (not shown)). Receive an email. As a result, the MFP 10 can receive print data from the portable terminal 50 via the mail server 120 (that is, via the Internet). For example, when the selection result is CP, the CPU 32 receives print data from the print CL server 140 via the wireless LAN I / F 20 or other I / F. As a result, the MFP 10 can receive print data from the portable terminal 50 via the print CL server 140 (that is, via the Internet).

  For example, when the selection result is DP, the CPU 32 receives print data via the wireless LAN I / F 20 or the BTI / F 24 using normal Wi-Fi NW, WFDNW, or BTNW. As a result, the portable terminal 50 can receive print data from the MFP 10 via the LAN (that is, not via the Internet).

  Next, in S <b> 134, the CPU 32 supplies print data to the printing mechanism 16. Thereby, the printing mechanism 16 prints the image represented by the print data on the print medium. Since the print data is an image file or the like, it has a relatively large data size. The communication speed of NFC communication via the NFC I / Fs 22 and 62 is slower than the communication speed of communication via other I / Fs (for example, wireless LAN I / Fs 20 and 60). Accordingly, if a configuration in which print data communication is performed between the MFP 10 and the portable terminal 50 using NFC communication is employed, a long time is required for print data communication. On the other hand, in the present embodiment, the MFP 10 and the portable terminal 50 execute communication of print data using communication different from NFC communication, and therefore can quickly execute communication of print data.

(Specific case: FIGS. 12 to 14)
A specific case of the present embodiment will be described with reference to FIGS. In FIGS. 12 to 14, like the MFPs 10A and 10B, reference numerals different from those of the MFP 10 in FIG. If there is a difference between the MFP (MFP 10A or the like) in each case and the MFP 10 in FIG. 1, the difference will be described before the contents of each case are described.

(Case A; FIG. 12)
In case A, the MFP 10A can execute normal Wi-Fi printing, BT printing, EP, and CP, but cannot execute WFD printing. The MFP 10A and the portable terminal 50 belong to a normal Wi-Fi NW formed by the AP 100. In normal Wi-Fi NW, “X1” is used as the SSID and “Y1” is used as the BSSID. The user of the portable terminal 50 brings the portable terminal 50 closer to the MFP 10A after starting the MFP application. As a result, an NFC connection is established between the portable terminal 50 and the MFP 10A. The portable terminal 50 transmits a function request to the MFP 10A using the NFC connection (S10 in FIG. 3).

  When the MFP 10A receives the function request from the portable terminal 50 (S60 in FIG. 7), the MFP 10A executes each confirmation process (S70, S80, S90 in FIG. 7), and then information indicating DPOK, information indicating EPOK, Response data including information indicating CPOK, and SSID “X1” and BSSID “Y1” is generated (S100 in FIG. 7). Note that the MFP 10A cannot execute WFD printing, but can execute normal Wi-Fi printing and BT printing. Therefore, the response data includes information indicating DPOK. The MFP 10A transmits the response data to the portable terminal 50 using the NFC connection (S102 in FIG. 7).

  The portable terminal 50 receives response data from the MFP 10A using the NFC connection. In this case, the set of SSID “X1” and BSSID “Y1” included in the response data is the same as the set of SSID “X1” and BSSID “Y1” included in the normal Wi-Fi WSI of the mobile terminal 50. Therefore (YES in S31 of FIG. 4), the portable terminal 50 selects the DP (S32 of FIG. 4). Using the NFC connection, the portable terminal 50 transmits a selection result indicating DP to the MFP 10A (S50 in FIG. 3).

  Upon receiving the selection result indicating DP (S104 in FIG. 7), the MFP 10A prepares transmission destination information (S110 in FIG. 7). Specifically, since information indicating normal Wi-Fi printing OK is stored in the memory 34 (YES in S112 in FIG. 11), the MFP 10A includes each information (SSID) included in the normal Wi-Fi WSI of the MFP 10A. "X1", BSSID "Y1", and IP address "IP1" of MFP 10A) are prepared as transmission destination information (S113). Since information indicating BT printing OK is stored in the memory 34 (YES in S116 of FIG. 11), the MFP 10A prepares BTWSI of the MFP 10A as transmission destination information (S117 of FIG. 11). The MFP 10A transmits the destination information to the portable terminal 50 (S130 in FIG. 7).

  When receiving the destination information from the MFP 10A (S52 in FIG. 3), the portable terminal 50 is included in the set of SSID “X1” and BSSID “Y1” included in the destination information and the normal Wi-Fi WSI of the portable terminal 50. It is determined that the set of SSID “X1” and BSSID “Y1” is the same (that is, MFP 10A and portable terminal 50 belong to the same normal Wi-Fi NW). Accordingly, the portable terminal 50 uses the normal Wi-Fi NW preferentially and transmits the print data to the MFP 10A via the AP 100 (S54 in FIG. 3). As a result, the printing process is executed in the MFP 10A (S134 in FIG. 7).

  As described above, when the MFP 10A and the portable terminal 50 belong to the same normal Wi-Fi NW, the portable terminal 50 has three printing functions (that is, DP, EP, CP) that can be executed by the MFP 10A. An appropriate printing function (ie DP) can be automatically selected from among them. That is, the portable terminal 50 automatically selects an appropriate communication method (that is, the direct method) from the three communication methods that can be used by the MFP 10A (that is, the direct method, the e-mail method, and the cloud method). Can do. Accordingly, the portable terminal 50 can appropriately transmit the print data to the MFP 10A using the selected communication method.

(Case B; FIG. 13)
In Case B, the MFP 10B can execute normal Wi-Fi printing, WFD printing, BT printing, and CP, but cannot execute EP. The MFP 10B belongs to a normal Wi-Fi NW (SSID “X1”, BSSID “Y1”) formed by the AP 100A. In addition, the MFP 10B belongs to the WFDNW (SSID “X3”, BSSID “Y3”) in which the PC 110 is a G / O device as a CL device. The portable terminal 50 belongs to a normal Wi-Fi NW (SSID “X2”, BSSID “Y2”) formed by an AP 100B different from the AP 100A.

  Each process until the MFP 10B receives the function request is the same as in the case A. The MFP 10B responds including information indicating DPOK, information indicating EPNG, information indicating CPOK, a set of SSID “X1” and BSSID “Y1”, and a set of SSID “X3” and BSSID “Y3”. Data is generated (S100 in FIG. 7), and response data is transmitted to the portable terminal 50 using the NFC connection (S102 in FIG. 7).

  In this case, the set of SSID “X1” and BSSID “Y1” included in the response data is not the same as the set of SSID “X2” and BSSID “Y2” included in the normal Wi-Fi WSI of the mobile terminal 50. Furthermore, the set of SSID “X3” and BSSID “Y3” included in the response data is not the same as the set of SSID “X2” and BSSID “Y2” included in the normal Wi-Fi WSI of the portable terminal 50 (FIG. 4). NO in S31). Moreover, the portable terminal 50 belongs to normal Wi-Fi NW (YES in S33). The portable terminal 50 can transmit a signal to the confirmation server 130 and receive a response signal from the confirmation server 130 (YES in S34). For this purpose, the portable terminal 50 executes a first selection process (S150).

  In the first selection process (FIG. 5), CP and EP are prioritized over DP. Since the response data includes information indicating DPOK and CPOK, the portable terminal 50 selects a CP from two print functions (that is, DP and CP) that can be executed by the MFP 10B (S152 in FIG. 5). . The portable terminal 50 transmits the selection result indicating the CP to the MFP 10B using the NFC connection (S50 in FIG. 3).

  Upon receiving the selection result indicating the CP (S104 in FIG. 7), the MFP 10B prepares transmission destination information (S110 in FIG. 7). Specifically, the MFP 10B prepares each piece of information (such as the URL of the print CL server 140) included in the printing CSI of the MFP 10B as transmission destination information (S120 in FIG. 11). The MFP 10B transmits the destination information to the portable terminal 50 (S130 in FIG. 7).

  When receiving the destination information from the MFP 10B (S52 in FIG. 3), the portable terminal 50 transmits the print data to the print CL server 140 using the print CSI included in the destination information (S54). Since the mobile terminal 50 belongs to the normal Wi-Fi NW, the mobile terminal 50 prints the print data not via the cellular NWI / F 66 but via the wireless LAN I / F 60 (that is, using the normal Wi-Fi NW). Transmit to the CL server 140. That is, the print data is transmitted to the MFP 10B via the AP 100B and the print CL server 140.

  As described above, when the portable terminal 50 belongs to the normal Wi-Fi NW, the portable terminal 50 appropriately selects the CP from the two print functions (that is, DP and CP) that can be executed by the MFP 10B. Can do. Thereby, the portable terminal 50 does not need to newly establish a wireless connection with the MFP 10B, and the processing load on the portable terminal 50 can be reduced. Furthermore, since the mobile terminal 50 uses normal Wi-Fi NW instead of cellular NW, print data communication is not charged.

(Case C; FIG. 14)
In case C, the MFP 10B is the same device as the MFP 10B in case B, and can execute normal Wi-Fi printing, WFD printing, BT printing, and CP, but cannot execute EP. The MFP 10B belongs to the normal Wi-Fi NW (SSID “X1”, BSSID “Y1”) formed by the AP 100, but does not belong to the WFDNW. The portable terminal 50 does not belong to the wireless LAN (that is, normal Wi-Fi NW, WFDNW) but belongs to the cellular NW.

  Each process until the MFP 10B receives the function request is the same as in the case A. The MFP 10B generates response data including information indicating DPOK, information indicating EPNG, information indicating CPOK, and SSID “X1” and BSSID “Y1” (S100 in FIG. 7), and uses the NFC connection. Then, the response data is transmitted to the portable terminal 50 (S102 in FIG. 7).

  In this case, neither the normal Wi-Fi WSI nor the WFD WSI of the mobile terminal 50 is stored in the memory 74 (NO in S31 of FIG. 4). Further, the portable terminal 50 does not belong to the wireless LAN (NO in S33 of FIG. 4), and belongs to the cellular NW (YES in S38 of FIG. 4). For this purpose, the portable terminal 50 executes a second selection process (S160).

  In the second selection process (FIG. 6), DP is prioritized over CP and EP. Since the response data includes information indicating DPOK and CPOK, the portable terminal 50 selects a DP from two print functions (that is, DP and CP) that can be executed by the MFP 10B (S162 in FIG. 6). . The portable terminal 50 transmits the selection result indicating DP to the MFP 10B using the NFC connection (S50 in FIG. 3).

  Upon receiving the selection result indicating DP (S104 in FIG. 7), the MFP 10B prepares transmission destination information (S110 in FIG. 7). Specifically, since information indicating normal Wi-Fi printing OK is stored in the memory 34 (YES in S112 in FIG. 11), the MFP 10B includes each information (SSID) included in the normal Wi-Fi WSI of the MFP 10B. "X1", BSSID "Y1", and IP address "IP1" of MFP 10A) are prepared as transmission destination information (S113). Further, since information indicating WFD printing OK is stored in the memory 34 (YES in S114), the MFP 10B spontaneously shifts to the G / O state, generates WFD WSI, and includes each of the WFD WSI included in the WFD WSI. Information (SSID “X3”, BSSID “Y3”, IP address “IP3” of MFP 10A, password “PW”) is prepared as destination information (S115). Note that since the MFP 10B is a G / O device, the WFD WSI includes a password. Further, since information indicating BT printing OK is stored in the memory 34 (YES in S116), the MFP 10B prepares BTWSI of the MFP 10B as transmission destination information (S117). The MFP 10B transmits the destination information to the portable terminal 50 (S130 in FIG. 7).

  When the portable terminal 50 receives the destination information from the MFP 10B (S52 in FIG. 3), the MFP 10A and the portable terminal 50 do not belong to the same NW, and therefore transmit print data using normal Wi-Fi NW. (S54). The portable terminal 50 determines to preferentially use the WFD WSI corresponding to the WFD communication having a high communication speed among the WFD WSI and BTWSI included in the transmission destination information (that is, to transmit print data using the WFDNW). To do. That is, the portable terminal 50 transmits a connection request for the MFP 10B to participate in the WFDNW, which is a G / O device, to the MFP 10B via the wireless LAN I / F 60 (S54). Thereby, a wireless connection is established between the MFP 10B and the portable terminal 50, and the portable terminal 50 can participate in the WFDNW as a CL device. The portable terminal 50 transmits print data to the MFP 10B via the wireless LAN I / F 60. Accordingly, the portable terminal 50 can transmit print data to the MFP 10B using WFDNW without using other devices.

  As described above, when the portable terminal 50 does not belong to the wireless LAN and belongs to the cellular network NW, the portable terminal 50 can select from two print functions (that is, DP and CP) that can be executed by the MFP 10A. DP can be selected appropriately. Thereby, since the portable terminal 50 uses WFDNW instead of cellular NW, communication of print data is not charged.

(Correspondence)
The portable terminal 50 and the MFP 10 are examples of “terminal device” and “first function execution device”, respectively. In case A of FIG. 12, the three communication methods DP, EP, and CP are examples of “M1 communication methods”, and DP is an example of “specific communication method”. In case B of FIG. 13, the two communication methods DP and CP are examples of “M1 communication methods” and CP is an example of “specific communication method”. In case C of FIG. 14, the two communication methods DP and CP are examples of “M1 communication methods”, and DP is an example of “specific communication method”.

  Note that the MFP 10A in case A in FIG. 12 and the MFP 10B in case B in FIG. 13 can also be considered as examples of “first function execution device” and “second function execution device”. In this case, in case B, the two communication methods of DP and CP are examples of “M2 communication methods”, and CP is an example of “a communication method different from a specific communication method”.

  The NFC I / F 62 and the wireless LAN I / F 60 are examples of the “first interface” and the “second interface”, respectively. The response data of case A and the response data of case B in FIG. 12 are examples of “first information” and “second information”, respectively. CP, DP, printing CSI, and confirmation server 130 are examples of “first communication method”, “second communication method”, “first communication setting information”, and “server”, respectively. The normal Wi-Fi NW in case A is an example of a “specific local area network”. Information (that is, DPOK, EPOK, CPOK) included in the response data of case A is an example of “first data”. In case A, if the printing CSI is not stored in the MFP 10A (NO in S92 in FIG. 10), the response data indicates DPOK, EPOK, and CPNG. In case A, if the MFP 10A cannot communicate with the confirmation server 130 (NO in S93 in FIG. 10), the response data indicates DPOK, EPOK, and CPNG. Information (that is, DPOK, EPOK, CPNG) included in the response data in these cases is an example of “second data”.

  The process of S12, the process of S30, the process of S50, the process of S52, and the process of S54 are respectively “first receiving unit”, “selecting unit”, and “second transmission” of “terminal device”. This is an example of processing executed by the “part”, “second receiver”, and “first transmitter”.

(Second embodiment)
Differences from the first embodiment will be described. Also in this embodiment, the mobile terminal 50 transmits print data to the MFP 10 according to the communication method selected by the mobile terminal 50. In the first embodiment, after receiving the selection result, the MFP 10 transmits the transmission destination information to the portable terminal 50. In this embodiment, the MFP 10 transmits response data including the transmission destination information to the portable terminal 50. .

(Application processing of portable terminal 50; FIG. 15)
With reference to FIG. 15, the contents of processing realized by the MFP application of this embodiment will be described. S10 is the same as S10 of FIG. In S <b> 12-2, the CPU 72 receives response data including transmission destination information from the MFP 10 via the NFC I / F 62.

  As described above, in the first embodiment, only one piece of transmission destination information corresponding to the print function (ie, DP, EP, or CP) indicated by the selection result is received in S52 of FIG. For example, when the selection result is EP, only transmission destination information (that is, email address) corresponding to EP is received, transmission destination information corresponding to DP (that is, normal Wi-Fi WSI, etc.), and CP. Destination information (i.e., CSI for printing) is not received.

  On the other hand, in this embodiment, the response data received in S12-2 includes all of one or more pieces of destination information corresponding to one or more printing functions (DP, EP, CP) that can be executed by the MFP 10. including. For example, when the MFP 10 is DPOK, EPOK, or CPOK, transmission destination information corresponding to DP (ie, normal Wi-Fi WSI), transmission destination information corresponding to EP (ie, email address), Three pieces of destination information, ie, destination information corresponding to the CP (that is, CSI for printing) are received.

  As described above, in this embodiment, the CPU 72 executes one-way communication, that is, transmission of a function request (S10) and reception of response data such as DPOK (S12-2). That is, the CPU 72 executes one round-trip communication in one NFC connection. When S12-2 is finished, the NFC connection is disconnected.

  S30 is the same as S30 of FIG. Next, in S54, the CPU 72 transmits print data to the MFP 10 using the transmission destination information corresponding to the selection result of the function selection process in S30 among the one or more transmission destination information received in S12-2. To do.

  For example, a situation is assumed in which all three pieces of transmission destination information are received in S12-2. When the selection result is EP, the CPU 72 transmits an e-mail including print data using the transmission destination information (that is, an e-mail address) corresponding to the EP among the three transmission destination information. If the selection result is CP, the CPU 72 uses the transmission destination information (that is, CSI for printing) corresponding to the CP among the three pieces of transmission destination information to send the print data to the print CL server 140. Send. When the selection result is DP, the CPU 72 transmits print data to the MFP 10 using the transmission destination information (that is, normal Wi-Fi WSI or the like) corresponding to the DP among the three transmission destination information. To do. Note that when the selection result is DP, the NW to which both the MFP 10 and the portable terminal 50 belong is preferentially used as in the first embodiment.

  As described above, in this embodiment, since the portable terminal 50 can receive response data including transmission destination information from the MFP 10, the print data is transmitted to the MFP 10 using the transmission destination information. Can do. Accordingly, as in the first embodiment, the portable terminal 50 does not need to send the selection result to the MFP 10, and the MFP 10 does not need to send the transmission destination information corresponding to the selection result to the portable terminal 50. For this reason, transmission of print data from the portable terminal 50 to the MFP 10 can be quickly executed.

(Processing of MFP 10; FIG. 16)
With reference to FIG. 16, the contents of the process executed by the MFP 10 of this embodiment will be described. S60 to S90 are the same as S60 to S90 of FIG. In S210, the CPU 32 executes transmission destination information preparation processing. The contents of the destination information preparation process will be described in detail later. Next, in S100-2, the CPU 32 generates response data including the destination information prepared in S210. S102, S132, and S134 are the same as S102, S132, and S134 of FIG.

(Destination information preparation process; FIG. 17)
With reference to FIG. 17, the contents of the destination information preparation process in S210 of FIG. 16 will be described. S302 to S307 are the same as S112 to S117 of FIG. In S308, the CPU 32 determines whether or not the information indicating EPOK is stored in the memory 34 in S80 of FIG. 16 (see FIG. 9). If the information indicating EPOK is stored in the memory 34, the CPU 32 determines YES in S308, and proceeds to S309. If the information indicating EPNG is stored in the memory 34, the CPU 32 determines NO in S308. Judge and proceed to S310. S309 is the same as S119 in FIG.

  In S310, the CPU 32 determines whether or not information indicating CPOK is stored in the memory 34 in S90 of FIG. 16 (see FIG. 10). If the information indicating CPOK is stored in the memory 34, the CPU 32 determines YES in S310, and proceeds to S311. If the information indicating CPNG is stored in the memory 34, the CPU 32 determines NO in S310. The transmission destination information preparation process is terminated. S311 is the same as S120 of FIG.

  In the transmission destination information preparation process of FIG. 17, all of one or more transmission destination information corresponding to one or more printing functions (DP, EP, CP) that can be executed by the MFP 10 are prepared. For example, when the MFP 10 is DPOK, EPOK, and CPOK, the destination information (S303, S305, S307) corresponding to DP, the destination information (S309) corresponding to EP, and the CP are supported. Three pieces of transmission destination information are prepared: transmission destination information (S311).

(Specific case; Fig. 18)
With reference to FIG. 18, a specific case realized by the processes of FIGS. 15 and 16 will be described. The MFP 10C can execute normal Wi-Fi printing, BT printing, EP, and CP, but cannot execute WFD printing. Further, the MFP 10 </ b> C and the mobile terminal 50 belong to a normal Wi-Fi NW (SSID “X1”, BSSID “Y1”) formed by the AP 100.

  In this case, the response data transmitted from the MFP 10C to the portable terminal 50 includes not only information indicating DPOK, information indicating EPOK, and information indicating CPNG, but also transmission destination information corresponding to DP (ie, “X1, Y1, IP1 ”,“ BTWSI ”), destination information corresponding to the EP (ie, the mail address“ E1 ”of the MFP 10), and destination information corresponding to the CP (ie,“ CSI for printing ”). Included (S210 in FIG. 16). That is, the response data includes three pieces of transmission destination information.

  Thereafter, as in the case A of FIG. 12, the portable terminal 50 selects the DP from the three printing functions (that is, DP, EP, CP) that can be executed by the MFP 10C (S30 of FIG. 15). Then, the portable terminal 50 transmits the print data to the MFP 10C using the transmission destination information corresponding to the DP among the three transmission destination information included in the response data (S54 in FIG. 15). More specifically, the mobile terminal 50 decides to preferentially use the normal Wi-Fi NW to which both the MFP 10C and the mobile terminal 50 belong (that is, preferentially uses the normal Wi-Fi WSI). As a result, the portable terminal 50 can transmit print data to the MFP 10C via the AP 100. In the case of FIG. 18, the three pieces of transmission destination information included in the response data are an example of “M1 pieces of transmission destination information”.

(Third embodiment)
Differences from the second embodiment will be described. In the present embodiment, the mobile terminal 50 can limit the types of print functions that can be selected by the mobile terminal 50 by executing a function confirmation process (S400 in FIG. 15) described later.

(Application processing of portable terminal 50; FIG. 15)
In this embodiment, the response data received in S12-2 further includes the device ID of the MFP 10 (see S100-2 in FIG. 16). The device ID is a unique ID assigned to the MFP 10 by the vendor of the MFP 10. Next, the CPU 72 executes a function confirmation process in S400. As will be described in detail later, in the function confirmation process, information (DPOK, EPOK, CPOK) described in the response data can be changed (see FIG. 19). For this reason, the types of print functions selected in the function selection process of S30, that is, the types of print functions that can be selected by the portable terminal 50 can be limited. Other processes are the same as in the second embodiment.

(Function confirmation process of portable terminal 50; FIG. 19)
With reference to FIG. 19, the function confirmation processing in S400 of FIG. 15 will be described. In S402, the CPU 72 determines whether or not information indicating DPOK is included in the response data. If the information indicating DPOK is included in the response data, the CPU 72 determines YES in S402 and proceeds to S404. On the other hand, if the information indicating DPNG is included in the response data, the CPU 72 determines NO in S402 and proceeds to S412.

  In S404, the CPU 72 determines whether the MFP 10 and the portable terminal 50 belong to the same normal Wi-Fi NW or the same WFDNW. If neither the normal Wi-Fi WSI nor the WFD WSI of the portable terminal 50 is stored in the memory 74, the CPU 72 determines NO in S404 and proceeds to S406.

  When the normal Wi-Fi WSI of the mobile terminal 50 is stored in the memory 74, the CPU 72 matches the set of the normal Wi-Fi SSID and the normal Wi-Fi BSSID included in the normal Wi-Fi WSI. And whether or not a set of BSSIDs (hereinafter referred to as “first set”) is included in the response data. If the first set is included in the response data, the CPU 72 determines YES in S404, and proceeds to S412. If the first set is not included in the response data, the CPU 72 determines NO in S404. Judge and proceed to S406.

  In addition, when the WFD WSI of the portable terminal 50 is stored in the memory 74, the CPU 72 sets the SSID and BSSID that match the set of the WFD SSID and WSID BSSID of the WFD WSI (hereinafter referred to as “second set”). ") Is included in the response data. If the second set is included in the response data, the CPU 72 determines YES in S404, and proceeds to S412. If the second set is not included in the response data, the CPU 72 determines NO in S404. Judge and proceed to S406.

  In S406, the CPU 72 determines whether or not the WFD WSI password of the MFP 10 is included in the response data. As described above, when the MFP 10 is in the G / O state, the response data includes the WFD WSI password of the MFP 10 (see S305 in FIG. 17). If the password is included in the response data, the CPU 72 determines YES in S406, and proceeds to S412. If the password is not included in the response data, the CPU 72 determines NO in S406, and S408. Proceed to

  In S408, the CPU 72 determines whether the BTWSI of the MFP 10 is included in the response data. If the BTWSI is included in the response data, the CPU 72 determines YES in S408, and proceeds to S412. If the BTWSI is not included in the response data, the CPU 72 determines NO in S408, and S410. Proceed to

  If all of S404, S406, and S408 are determined to be NO, the LAN to which both the MFP 10 and the portable terminal 50 belong is not realized. Cannot be used to communicate print data. Therefore, in S410, the CPU 72 changes the information indicating DPOK included in the response data received in S12-1 of FIG. 15 to information indicating DPNG. Thereby, in S30 of FIG. 15, CPU72 cannot select DP. When S410 ends, the process proceeds to S412.

  In S412, the CPU 72 determines whether or not information indicating EPOK is included in the response data. If the information indicating EPOK is included in the response data, the CPU 72 determines YES in S412 and proceeds to S414. On the other hand, when the information indicating EPNG is included in the response data, the CPU 72 determines NO in S412 and proceeds to S418.

  In S <b> 414, the CPU 72 determines whether or not ESI for transmission, which is ESI for transmitting E-mail, is stored in the memory 74. If the transmission ESI is stored in the memory 74, the CPU 72 determines YES in S414, and proceeds to S418. If the transmission ESI is not stored in the memory 74, the CPU 72 determines NO in S414. , The process proceeds to S416.

  If NO is determined in S416, since the portable terminal 50 cannot transmit an email, the MFP 10 and the portable terminal 50 communicate print data by using an email communication method. I can't. For this reason, in S416, the CPU 72 changes the information indicating EPOK included in the response data received in S12-1 of FIG. 15 to information indicating EPNG. Thereby, in S30 of FIG. 15, CPU72 cannot select EP. When S416 ends, the process proceeds to S418.

  In S418, the CPU 72 determines whether or not information indicating CPOK is included in the response data. When the information indicating CPOK is included in the response data, the CPU 72 determines YES in S418, and proceeds to S420. On the other hand, if the information indicating CPNG is included in the response data, the CPU 72 determines NO in S418 and ends the function confirmation process.

  As described above, the response data received in S12-2 of FIG. 15 includes the device ID of the MFP 10. In S420, the CPU 72 transmits an inquiry signal including the device ID of the MFP 10 to the confirmation server 130 via the wireless LAN I / F 60 or another I / F (for example, the cellular NWI / F 66).

  When the confirmation server 130 receives the inquiry signal including the device ID of the MFP 10, the confirmation server 130 determines whether or not a connection is established between the MFP 10 and the print CL server 140. For example, the confirmation server 130 supplies the device ID of the MFP 10 to the print CL server 140 and acquires information indicating the presence or absence of the connection from the print CL server 140. Then, the confirmation server 130 transmits an inquiry result indicating connection or non-connection to the MFP 10 according to the acquired information.

  In S422, the CPU 72 determines whether or not the inquiry result received from the confirmation server 130 indicates connection. If the inquiry result indicates connection, the CPU 72 determines YES in S422, ends the function confirmation process, and if the inquiry result indicates disconnection, determines NO in S422 and proceeds to S424.

  In this embodiment, the MFP 10 must be always connected to the print CL server 140 in order to receive print data from the print CL server 140. Accordingly, if NO is determined in step S422, the MFP 10 and the portable terminal 50 use the cloud communication method to print data because the MFP 10 cannot receive print data from the print CL server 140. Can't communicate. To this end, in S424, the CPU 72 changes the information indicating CPOK included in the response data received in S12-1 of FIG. 15 to information indicating CPNG. Thereby, in S30 of FIG. 15, CPU72 cannot select CP. When S424 ends, the function confirmation process ends.

(Specific case: Fig. 20)
With reference to FIG. 20, a specific case realized by each processing of FIG. 15 (especially S400) and FIG. The MFP 10D can execute normal Wi-Fi printing, BT printing, EP, and CP, and cannot execute WFD printing. The MFP 10D and the portable terminal 50 belong to a normal Wi-Fi NW (SSID “X1”, BSSID “Y1”) formed by the AP 100.

  In this case, the response data transmitted from the MFP 10D to the portable terminal 50 includes the device ID of the MFP 10D, information indicating DPOK, information indicating EPOK, information indicating CPOK, and transmission destination information corresponding to DP (ie, , “X1, Y1, IP1”, “BTWSI”), destination information corresponding to EP (ie, mail address “E1” of MFP 10D), and destination information corresponding to CP (ie, printing CSI) (S210, S100-2 in FIG. 16).

  Next, the portable terminal 50 executes a function confirmation process (S400 in FIG. 15). Since the response data includes a set of SSID and BSSID that match the set of “X1” and “Y1” of the normal Wi-Fi NW to which the mobile terminal 50 belongs (YES in S404 of FIG. 19), the mobile phone The terminal 50 does not change the information indicating DPOK to information indicating DPNG.

  In this case, since the transmission ESI for executing the transmission of the e-mail is not stored in the memory 74 of the portable terminal 50 (NO in S414 in FIG. 19), the portable terminal 50 displays the information indicating the EPOK. , The information is changed to information indicating EPNG (S416).

  The portable terminal 50 transmits an inquiry signal including the device ID of the MFP 10D to the confirmation server 130, and acquires the inquiry result from the confirmation server 130 (S422 in FIG. 19). In this case, the printing CSI is stored in the memory 34 of the MFP 10D, but the MFP 10D is not connected to the print CL server 140. For example, when the expiration date of the authentication information included in the print CSI has expired, an event that the MFP 10D cannot connect to the print CL server 140 may occur. In this case, the portable terminal 50 determines NO in S422 of FIG. 19 and changes the information indicating CPOK to information indicating CPNG (S424).

  As described above, the response data received from MFP 10D includes information indicating DPOK, EPOK, and CPOK. However, in the function confirmation process (S400 in FIG. 15), the response data is changed to information indicating DPOK and information indicating EPNG and CPNG. As a result, the portable terminal 50 selects the DP from the three printing functions (that is, DP, EP, CP) that can be executed by the MFP 10D. Then, the mobile terminal 50 uses the normal Wi-Fi NW preferentially and transmits the print data to the MFP 10D via the AP 100 (S54 in FIG. 15).

  According to the present embodiment, it is possible to suppress the communication method (EP and CP in the case of FIG. 20) that cannot be used for transmission of print data from the portable terminal 50 to the MFP 10D being selected by the portable terminal 50. . In the present embodiment, the MFP 10D and the portable terminal 50 can appropriately execute print data communication using a communication method selected by the portable terminal 50 (DP in the case of FIG. 20).

(Correspondence)
In the case of FIG. 20, the SSID “X1” and the BSSID “Y1” included in the response data are examples of “identification information”. CP, DP, and EP are examples of the “first communication method”, the “second communication method”, and the “third communication method”, respectively. Information included in the response data (that is, DPOK, EPOK, CPOK) is an example of “third data” and “fourth data”. The processes in S404 and S414 in FIG. 19 are examples of processes executed by the “first determination unit” and the “second determination unit” of the “terminal device”, respectively. The ESI for transmission that is the determination target in S414 is an example of “second wireless setting information”.

(Fourth embodiment)
Differences from the first embodiment will be described. In this embodiment, the portable terminal 50 does not execute the function selection process, and the MFP 10 executes the function selection process.

(Application processing of portable terminal 50; FIG. 21)
With reference to FIG. 21, the contents of processing realized by the MFP application of this embodiment will be described. The function request transmitted in S10-4 includes information indicating whether or not the portable terminal 50 belongs to the wireless LAN and information indicating whether or not the portable terminal 50 belongs to the cellular network. When the portable terminal 50 belongs to a wireless LAN (that is, when normal Wi-Fi WSI or WFD WSI is stored in the memory 74), the function request further includes a set of the SSID and BSSID of the wireless LAN. Including. The MFP 10 can execute a function selection process (S30 in FIG. 22) described later using these pieces of information.

  The response data received in S12-4 includes a selection result (that is, DP, EP, or CP) of the function selection process executed by the MFP 10 and transmission destination information corresponding to the selection result. Next, in S54, the CPU 72 transmits the print data to the MFP 10 according to the communication method corresponding to the selection result using the transmission destination information corresponding to the selection result.

(Processing of MFP; FIG. 22)
With reference to FIG. 22, the contents of the process executed by the MFP 10 of this embodiment will be described. S60 to 90 are substantially the same as S60 to 90 in FIG. However, as described above, the function request received in S60 includes information indicating whether the portable terminal 50 belongs to the wireless LAN and information indicating whether the portable terminal 50 belongs to the cellular network. And including. Further, the function request may include a set of SSID and BSSID of the wireless LAN to which the mobile terminal 50 belongs. In S70, when at least one of normal Wi-Fi printing, WFD printing, and BT printing is OK, the CPU 32 stores information indicating DPOK in the memory 34, and all of them are NG. If it is, information indicating DPNG is stored in the memory 34.

  In S30, the CPU 32 executes a function selection process. The function execution process of the present embodiment is the same as the function execution process of the first embodiment except that the execution subject is the CPU 32 (see S30 in FIG. 3 and FIGS. 4 to 6). In addition, when the set of SSID and BSSID is included in the function request, the CPU 32 executes the process of S31 of FIG. 4 using the set. In addition, the CPU 32 displays each information included in the function request (that is, information indicating whether or not the portable terminal 50 belongs to the wireless LAN, information indicating whether or not the portable terminal 50 belongs to the cellular network). Utilizing this, the processing of S33 and S38 of FIG. 4 is executed.

  22 is the same as S110 in FIG. 7 (that is, FIG. 11). The response data transmitted in S100-4 includes the selection result of the function selection process in S30 and the transmission destination information prepared in S110. S102, S132, and S134 are the same as S102, S132, and S134 of FIG. 7, respectively.

(Specific case; Fig. 23)
With reference to FIG. 23, a specific case realized by each processing of FIG. 21 and FIG. 22 will be described. The MFP 10E can execute normal Wi-Fi printing, BT printing, EP, and CP, but cannot execute WFD printing. The MFP 10D and the portable terminal 50 belong to a normal Wi-Fi NW (SSID “X1”, BSSID “Y1”) formed by the AP 100. Note that the mobile terminal 50 does not belong to the cellular network.

  In this case, the function request transmitted from the portable terminal 50 to the MFP 10E includes information indicating that the portable terminal 50 belongs to the wireless LAN, and information indicating that the portable terminal 50 does not belong to the cellular network. And a set of SSID “X1” and BSSID “Y1” of the normal Wi-Fi NW to which the portable terminal 50 belongs (S10-4 in FIG. 21).

  When the MFP 10E receives a function request from the portable terminal 50 (S60 in FIG. 22), the MFP 10E executes each function confirmation process (S70 to 90 in FIG. 22), and displays information indicating DPOK, information indicating EPOK, and CPOK. Information to be stored in the memory 34.

  In this case, since the set of SSID and BSSID that matches the set of SSID “X1” and BSSID “Y1” included in the normal Wi-Fi WSI of MFP 10E is included in the function request (YES in S31 of FIG. 4), MFP 10E. Selects the DP from the three printing functions (that is, DP, EP, CP) that can be executed by the MFP 10E (S32 in FIG. 4).

  The response data transmitted from the MFP 10E to the portable terminal 50 includes not only the selection result indicating DP but also normal Wi-Fi WSI (that is, “X1, Y1, IP1”) and BTWSI (S102 in FIG. 22). . The portable terminal 50 transmits print data to the MFP 10D via the AP 100 using the normal Wi-Fi NW preferentially (S54 in FIG. 21).

(Correspondence)
In the case of FIG. 23, DP, EP, and CP are examples of “M1 communication schemes”, and DP is an example of “specific communication schemes”. The processes of S30, S102, and S132 of FIG. 22 are examples of processes executed by the “selection unit”, “transmission unit”, and “first reception unit” of the “function execution device”, respectively. .

(5th Example)
Differences from the fourth embodiment will be described. In the present embodiment, the MFP 10 executes the DP function confirmation process in S70 of FIG. 22 according to a flowchart different from that of FIG.

(DP function confirmation processing; FIG. 24)
With reference to FIG. 24, the DP function confirmation processing in S70 of FIG. 22 will be described. S700 and S702 are the same as S71 and S73 of FIG. If YES in step S700, the process proceeds to step S704. If NO in step S700, the process proceeds to step S702. When S702 ends, the process proceeds to S720. In S704, the CPU 32 determines whether the MFP 10 and the portable terminal 50 belong to the same normal Wi-Fi NW. If the normal Wi-Fi WSI of the MFP 10 is not stored in the memory 34, the CPU 32 determines NO in S704, and proceeds to S708.

  When the normal Wi-Fi WSI of the MFP 10 is stored in the memory 34, the CPU 32 matches the SSID and BSSID that match the set of the normal Wi-Fi SSID and the normal Wi-Fi BSSID included in the normal Wi-Fi WSI. It is determined whether or not a set of functions (hereinafter referred to as “third set”) is included in the function request. If the third set is included in the function request, the CPU 32 determines YES in S704, and proceeds to S706. If the third set is not included in the function request, the CPU 32 determines NO in S704. Determination is made, and the process proceeds to S708.

  In S <b> 706, the CPU 32 stores information indicating normal Wi-Fi printing OK in the memory 34. In S <b> 708, the CPU 32 stores information indicating normal Wi-Fi printing NG in the memory 34. When S706 or S708 ends, the process proceeds to S710.

  S710 and S718 are the same as S74 and S76 in FIG. If YES in step S710, the process proceeds to step S712. If NO in step S710, the process proceeds to step S718. When S718 ends, the process proceeds to S720. In S712, the CPU 32 determines whether or not the current state of the MFP 10 is the CL state. If the current state of the MFP 10 is the CL state, the CPU 32 determines YES in S712, and proceeds to S714. If the current state of the MFP 10 is the G / O state or the device state, the CPU 32 determines NO in S712. The process proceeds to S716.

  In S <b> 714, the CPU 32 determines whether the MFP 10 and the portable terminal 50 belong to the same WFDNW. When the WFD WSI of the MFP 10 is stored in the memory 34, the CPU 32 sets a set of SSID and BSSID (hereinafter referred to as “fourth set”) that matches the set of the SFD for WFD and the BSSID for WFD included in the WFD WSI. Call) is included in the function request. If the fourth set is included in the function request, the CPU 32 determines YES in S714, and proceeds to S716. If the fourth set is not included in the function request, the CPU 32 determines NO in S714. Judge, and proceed to S718. S716 to S724 are the same as S75 to S79 in FIG.

  When the MFP 10 and the portable terminal 50 do not belong to the same normal Wi-Fi NW, the MFP 10 and the portable terminal 50 cannot execute print data communication using the normal Wi-Fi method. This is because the password included in the normal Wi-Fi WSI of the MFP 10 is not transmitted from the MFP 10 to the portable terminal 50 (S303 in FIG. 17), so that the portable terminal 50 may participate in the normal Wi-Fi NW to which the MFP 10 belongs. It is not possible. Therefore, in this embodiment, the MFP 10 has a normal Wi-Fi printing function, but when the MFP 10 and the portable terminal 50 do not belong to the same normal Wi-Fi NW (NO in S704). The normal Wi-Fi printing NG is stored in the memory 34 (S708).

  When the MFP 10 is in the CL state and the MFP 10 and the portable terminal 50 do not belong to the same WFDNW, the MFP 10 and the portable terminal 50 can execute print data communication using the WFD method. Can not. This is because the password included in the WFD WSI of the MFP 10 is not transmitted from the MFP 10 to the portable terminal 50 (see “MFP = CL” in S305 in FIG. 17), and the portable terminal 50 joins the WFDNW to which the MFP 10 belongs. Because you can't. Therefore, in this embodiment, the MFP 10 is in the case where the MFP 10 is in the CL state and the MFP 10 and the portable terminal 50 do not belong to the same WFDNW even if the MFP 10 has the WFD printing function (NO in S714). ), The WFD print NG is stored in the memory 34 (S718).

  As described above, in this embodiment, the MFP 10 stores information on normal Wi-Fi printing (OK or NG) and information on WFD printing (OK or NG) according to the status of the MFP 10 and the portable terminal 50 in the memory. 34 can be stored appropriately. As a result, in S <b> 30 of FIG. 22, the MFP 10 can appropriately perform selection related to DP.

(Specific case; Fig. 25)
With reference to FIG. 25, a specific case realized by each processing of FIG. 21 and FIG. 22 (particularly S70 (FIG. 24)) will be described. The MFP 10F belongs to a normal Wi-Fi NW (SSID “X1”, BSSID “Y1”) formed by the AP 100. The MFP 10F belongs to the WFDNW (SSID “X3”, BSSID “Y3”) formed by the PC 110 as a CL device. The MFP 10F can execute EP, but cannot execute BT printing and CP. The portable terminal 50 does not belong to the wireless LAN, but belongs to the cellular NW.

  In this case, the function request transmitted from the mobile terminal 50 to the MFP 10F includes information indicating that the mobile terminal 50 does not belong to the wireless LAN, and information indicating that the mobile terminal 50 belongs to the cellular network NW. ,including.

  A set that matches the set of the normal Wi-Fi SSID “X1” and the normal Wi-Fi BSSID “Y1” included in the normal Wi-Fi WSI of the MFP 10F is not included in the function request (S704 in FIG. 24). The MFP 10F stores information indicating normal Wi-Fi printing NG in the memory 34 (S708). Further, the MFP 10F is in the CL state (YES in S712), and the function request does not include a set that matches the set of the WFD SSID “X3” and the WFD BSSID “Y3” included in the WFD WSI of the MFP 10F. For this reason (NO in S714), the MFP 10F stores information indicating the WFD printing NG in the memory 34 (S718). Further, since the MFP 10F cannot execute BT printing (NO in S720), the MFP 10F stores information indicating the BT printing NG in the memory 34 (S724).

  Since all of normal Wi-Fi printing, WFD printing, and BT printing are NG, the MFP 10F stores information indicating DPNG in the memory 34. As described above, the MFP 10 </ b> F stores information indicating DPNG in the memory 34 even though normal Wi-Fi printing and WFD printing can be performed. Therefore, the MFP 10F does not select a DP that cannot execute print data communication in a second selection process (see FIG. 6) described later.

  Since the MFP 10F can execute EP, the MFP 10F stores information indicating EPOK in the memory 34 (S83 in FIG. 9). Further, since the MFP 10F can execute CP, the MFP 10F stores information indicating CPOK in the memory 34 (S94 in FIG. 10).

  As described above, the function request includes information indicating that it belongs to the cellular network. Therefore, the MFP 10F determines YES in S38 of FIG. 4 and executes the second selection process (S160). Then, the MFP 10F selects a CP from two print functions (EP, CP) that can be executed by the MFP 10F (YES in S163 of FIG. 6). The MFP 10F transmits response data including the selection result indicating the CP and the printing CSI that is the transmission destination information corresponding to the CP to the portable terminal 50 (S102 in FIG. 22).

  When the portable terminal 50 receives the response data from the MFP 10 (S12-4 in FIG. 21), the print data is sent to the print CL server 140 via the cellular NWI / F 66 using the print CSI included in the response data. Send. Accordingly, the print data is transmitted to the MFP 10F via the print CL server 140.

(Correspondence)
In the case of FIG. 25, the DP is an example of a “second communication method”. EP and CP are examples of “M1 communication methods not including the second communication method”. The process of S60 of FIG. 22 is an example of the process executed by the “second receiving unit” of the “function execution device”, and the processes of S704 and 714 of FIG. It is an example of the process performed by "."

  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. The modifications of the above embodiment are listed below.

(Modification 1)
In S93 of FIG. 10, the CPU 32 of the MFP 10 determines whether the MFP 10 can communicate with the confirmation server 130 on the Internet, and stores information indicating CPOK or information indicating CPNG in the memory 34. Instead, when the MFP 10 is connected to the AP 100 (that is, when normal Wi-Fi WSI is stored in the memory 34), the CPU 32 determines YES in S93, and the MFP 10 is connected to the AP 100. If not (ie, if normal Wi-Fi WSI is not stored in the memory 34), NO may be determined in S93. The AP 100 usually has a function of relaying communication between the wireless LAN and the Internet. For this reason, when the MFP 10 is connected to the AP 100, the MFP 10 can normally perform Internet communication. Therefore, the CPU 32 appropriately determines whether or not the MFP 10 can execute Internet communication (that is, whether or not the MFP 10 can communicate with the print CL server 140) by determining whether or not the MFP 10 is connected to the AP 100. can do.

(Modification 2)
In S <b> 12 of FIG. 3, the CPU 72 of the portable terminal 50 may receive response data including the device ID or model name of the MFP 10 instead of receiving response data including information indicating DPOK or the like. In this case, the CPU 72 transmits an inquiry signal including the device ID or model name of the MFP 10 to the confirmation server 130 and receives an inquiry result from the confirmation server 130. The confirmation server 130 stores information indicating which printing function (DP, EP, CP) the MFP 10 can execute in association with the device ID or model name of the MFP 10. The information is stored in advance in the confirmation server 130 by the vendor of the MFP 10. For example, when the MFP 10 does not have the EP function and the CP function, the vendor stores information indicating DPOK, EPNG, and CPNG in the confirmation server 130 in association with the device ID or model name of the MFP 10. . When the confirmation server 130 receives an inquiry signal including the device ID or model name of the MFP 10 from the portable terminal 50, the confirmation server 130 displays information indicating which print function (DP, EP, CP) the MFP 10 can execute. The inquiry result including this is transmitted to the portable terminal 50. The CPU 72 of the portable terminal 50 selects the print function in S30 of FIG. 3 according to the inquiry result. Also in this modification, the CPU 72 can select a print function that can be executed by the MFP 10. In the present modification, the device ID or model name of the MFP 10 is an example of “first information”.

(Modification 3)
In the second modification, the confirmation server 130 further associates the device ID or model name of the MFP 10 with the print conditions that can be executed by the MFP 10 (for example, the paper size that can be used by the MFP 10 and the print resolution that can be used by the MFP 10. Range, etc.) may be stored. When the confirmation server 130 receives an inquiry signal including the device ID or model name of the MFP 10 from the portable terminal 50, the confirmation server 130 indicates which print function (DP, EP, CP) the MFP 10 can execute. An inquiry result including information and information indicating printing conditions executable by the MFP 10 is transmitted to the portable terminal 50. In response to the inquiry result, the CPU 72 of the portable terminal 50 generates display data indicating the printing conditions included in the inquiry result, and supplies the display data to the display mechanism 54. Thereby, the user can select a printing condition.

  In S50 of FIG. 3, the CPU 72 performs not only the print function (for example, “DP”) selected by the CPU 72 but also the print condition (for example, paper size “A4”, print resolution “200 dpi”) selected by the user. May be transmitted to the MFP 10. In S134 of FIG. 7, the CPU 32 of the MFP 10 may execute the printing process according to the printing condition indicated by the selection result by the portable terminal 50.

(Modification 4)
The “first interface” is not limited to the NFC I / F 62, and may be, for example, a TJ I / F for executing Transfer Jet wireless communication. If the transfer jet wireless communication speed is increased, the wireless communication speed via the wireless LAN I / F 60 is slower than the wireless communication speed via the TJI / F. Also good. That is, the communication speed of the wireless communication via the “second interface” may be faster or slower than the communication speed of the wireless communication via the “first interface”. Generally speaking, it is sufficient that the communicable range of wireless communication via the “second interface” is larger than the communicable range of wireless communication via the “first interface”.

(Modification 5)
The “function execution device” is not limited to the MFP 10 and may be another communication device (printer, FAX device, copier, etc.) that can execute the print function.

(Modification 6)
In each of the above-described embodiments, the MFP 10 and the portable terminal 50 form a wireless network by performing WFD communication. Instead, the CPU 32 of the MFP 10 may form a wireless network in which the MFP 10 operates as an AP by activating so-called Soft AP.

(Modification 7)
In each of the embodiments described above, when a new WFDNW is formed, the MFP 10 becomes a G / O device. Instead, the mobile terminal 50 may be a G / O device. Further, the CPU 72 of the mobile terminal 50 may form a wireless network in which the mobile terminal 50 operates as an AP by activating so-called SoftAP.

(Modification 8)
The CPU 72 of the portable terminal 50 may accept the designation of print data at any timing among the processes in FIG. For example, the CPU 72 may accept designation of print data before sending a function request to the MFP 10 via the NFC I / F 62 (that is, before S10 in FIG. 3), or immediately before sending print data to the MFP 10. The designation of print data may be accepted (that is, immediately before S54).

(Modification 9)
In each of the embodiments described above, in the first selection process (FIG. 5) and the second selection process (FIG. 6), the CP is prioritized over the EP (S151, S153 in FIG. 5, S163 in FIG. 6, S165). Alternatively, EP may be given priority over CP.

(Modification 10)
In each of the above embodiments, when the mobile terminal 50 belongs to the wireless LAN (YES in S33 of FIG. 4) and CP or EP is selected (S152, S154 of FIG. 5), the CPU 72 Internet communication is executed via the wireless LAN I / F 60 (S54 in FIG. 3). On the other hand, when the portable terminal 50 does not belong to the wireless LAN (NO in S33 in FIG. 4), belongs to the cellular network (YES in S38), and CP or EP is selected (see FIG. 6 (S164, S166), the CPU 72 executes Internet communication via the cellular NWI / F 66 (S54 in FIG. 3). That is, in each of the embodiments described above, priority is given to Internet communication using a wireless LAN that is not subject to a metered charge, compared to Internet communication using a cellular network. Instead, Internet communication using cellular NW may be prioritized over Internet communication using wireless LAN.

(Modification 11)
In the above-described embodiment, the CPUs 32 and 72 of the MFP 10 and the portable terminal 50 execute the programs (that is, software) in the memories 34 and 74, thereby realizing each process of FIGS. Alternatively, at least one of the processes may be realized by hardware such as a logic circuit.
