  The display unit 102 receives an image signal output from the CPU 106 and displays an image based on the received image signal. As the display means 102, for example, an LCD or an organic EL panel can be used. The touch panel 103 is formed of a transparent member and is disposed so as to cover the surface of the display unit 102. The touch panel 103 detects a position touched by a user's finger or the like, and outputs the detected position information to the CPU 106. The input I / F 104 is, for example, an operation button.

  The NFC communication I / F 112 is an interface for executing the NFC wireless communication 153. In order to establish the NFC wireless communication 153, various pieces of information for communication setting (eg, IP address, SSID, etc.) are not necessary. The wireless LAN_I / F 105 is an interface for executing wireless communication 151, 152, 155 of the wireless LAN system.

The communication speeds of the wireless communication 151, 152, and 155 of the wireless LAN method are faster than the communication speed of the wireless communication 153 of the NFC method.

  CPU 106 executes a program stored in storage unit 109. The RAM 108 temporarily stores information necessary for the processing of the CPU 106. The storage unit 109 is configured by combining a flash memory, an HDD (hard disk), a buffer included in the CPU 106, and the like. The storage unit 109 can store image data, document data, and the like. The storage unit 109 stores a program 120. The program 120 includes a print & scan application 121 (hereinafter referred to as application 121) and an operating system 124 (hereinafter referred to as OS 124). The CPU 106 executes processing according to the program 120. Hereafter, the CPU 106 that executes a program, such as the application 121 or the OS 124, may be simply described as a program name. For example, the description “application 121” may mean “the CPU 106 executing the application 121”.

The application 121 is an application for causing the CPU 106 to execute processing for transmitting a print command from the information processing apparatus 100 to the MFP 51 or the like. The OS 124 is a program that provides basic functions that are commonly used by the application 121 and the like. The OS 124 includes a program for causing the wireless LAN_I / F 105 and the NFC communication I / F 112 to perform wireless communication. The OS 124 is also a program that provides an API (abbreviation of application programming interface) for each program to acquire information acquired by various hardware, or for each program to instruct the various hardware.

  The storage unit 109 stores a table TB1. The table TB1 is a table that stores specific device identification information for identifying a specific device and specific network identification information for identifying a specific network. The specific device is a device selected and set from a plurality of devices as a communication destination of the information processing apparatus 100. The specific network is a network set as a communication destination of communication using the wireless LAN_I / F 105 of the information processing apparatus 100. A network including a specific device may be set as the specific network.

  FIG. 4 shows an example of the table TB1. In the example of FIG. 4, a model number 601 and an IP address 602 are used as the specific device identification information 600. Further, SSID 603 is used as the specific network identification information. The model number 601 is information for identifying the type of each device. The IP address 602 is a well-known bit string assigned to each device and used for communication. The SSID 603 is an identifier for identifying access points constituting a specific network.

In the explanation example of the present embodiment, a case will be described in which the model numbers 601 of the devices of the MFPs 51 and 52 are “Ink-MFP1” and “Ink-MFP2”. A case will be described in which the IP addresses 602 of the MFPs 51 and 52 are “192.168.100.101” and “192.168.100.102”, respectively. Further, a case where the SSID of the first access point 501 configuring the network N1 is “SSID-1” and the SSID of the second access point 502 configuring the network N2 is “SSID-2” will be described. To do. 4, “Ink-MFP2” is stored as the model number 601, “192.168.100.102” is stored as the IP address 602, and “SSID-2” is stored as the SSID 603 in the table TB1. . That is, FIG. 4 illustrates a case where the MFP 52 is selected as the specific device and the network N2 is set as the specific network.

<Configuration of MFP 51>
A configuration of the MFP 51 will be described. The MFP 51 mainly includes a CPU 32, a storage unit 33, a wireless LAN_I / F 34, an NFC communication I / F 36, a button input unit 38, a panel 39, a printer 19, and a scanner 20. These components can communicate with each other via the input / output port 43.

  The CPU 32 executes the program 21 stored in the storage unit 33. The storage unit 33 is configured by combining RAM, ROM, flash memory, HDD (abbreviation of hard disk), a buffer provided in the CPU 72, and the like. The storage unit 33 stores the program 21. The program 21 includes an OS 29 and the like.

The NFC communication I / F 36 is an interface for executing the NFC wireless communication 153. The wireless LAN_I / F 34 is an interface for executing wireless LAN wireless communication 154 and 155. The button input unit 38 is a key for executing each function of the MFP 51. The button input unit 38 may be configured integrally with the panel 39 as a touch panel. The panel 39 displays various function information of the MFP 51. The printer 19 is a part that executes printing using the image data stored in the storage unit 33. The scanner 20 is a part that executes reading. Although the MFP 52 has the same configuration as the MFP 51, the illustration in FIG. 1 is omitted for the sake of simplification of the drawing.

<Operation of Application 121>
Hereinafter, a process in which the CPU 106 controls each unit according to the application 121 will be described with reference to FIGS. Further, in the explanation example of the present embodiment, a case where the network N2 is set as the specific network will be described. A case will be described in which the information processing apparatus 100 is connected to the network N2, which is a specific network. A case where the user holds the information processing apparatus 100 over the MFP 51 (that is, a case where the MFP 51 is selected as a communication target device) will be described.

  When the application 121 is activated, the flow of FIG. 2 is started. In S110, the application 121 determines whether or not the touch panel 103 has accepted an operation for selecting data to be printed. If not received (S110: NO), the process returns to S110, and if received (S110: YES), the process proceeds to S112. In step S112, the application 121 causes the display unit 102 to display a print preview. In addition, the communication partner device and the communication partner network are displayed on the display unit 102. In the example of this embodiment, as shown in FIG. 5, a print preview image P1 is displayed on the display unit 102. Further, as shown in an area R1 in FIG. 5, the model number of the specific device (that is, the MFP 52) is displayed as information indicating the communication partner device. In addition, as information indicating the communication partner network, the SSID (ie, SSID-2) of the second access point 502 included in the specific network (ie, network N2) is displayed.

  In S <b> 114, the application 121 determines whether or not notification information for starting NFC communication has been received from the OS 124. The NFC communication is started when the NFC communication I / F 112 provided in the information processing apparatus 100 approaches within a predetermined distance centered on the NFC communication I / F provided in the apparatus that is the target of NFC communication. Is done. The predetermined distance may be about 10 cm, for example. If the notification information has not been received from the OS 124 (S114: NO), the process returns to S114, and if received (S114: YES), the process proceeds to S116. In the description example of the present embodiment, a case where the user holds the information processing apparatus 100 over the MFP 51 is described. Therefore, notification information indicating that the NFC wireless communication 153 with the MFP 51 has been started is received from the OS 124.

  In S <b> 116, the application 121 acquires the SSID of the network to which the information processing apparatus 100 is currently connected from the OS 124. In the example of the present embodiment, a case is described in which the information processing apparatus 100 is connected to the network N2 that is a specific network. Therefore, the SSID (that is, SSID-2) of the second access point 502 included in the network N2 is acquired.

In S120, the application 121 transmits the acquired SSID to the communication target device using the NFC wireless communication 153. In the description example of the present embodiment, the SSID-2 of the second access point 502 is transmitted to the MFP 51 that is a communication target device. In step S121, the application 121 receives communication target device identification information from the communication target device using the NFC wireless communication 153. The communication target device identification information is information for identifying the communication target device. Examples of the communication target device identification information include the model number of the communication target device, the IP address of the communication target device, the SSID of the network including the communication target device, and the password for the SSID. The application 121 may receive coincidence determination information described later from the communication target device. In the example of this embodiment, the application 121 receives the model number (Ink-MFP1) of the MFP 51 that is the communication target device, the IP address (192.168.100.101), the SSID (SSID-1) of the network N1, and the like.

  In S122, the application 121 determines whether or not the network including the communication target device matches the specific network (that is, the network to which the information processing apparatus 100 is currently connected). The determination may be made based on the match determination information received from the communication target device in S121, for example. The match determination information is information indicating whether or not the network including the communication target device matches the specific network. The match determination information is generated by the communication target device. For example, the communication target device includes the SSID of a specific network (the SSID is transmitted to the communication target device in S120) and the SSID of the network to which the communication target device belongs (the SSID is stored in the communication target device, for example). Match determination information indicating that both networks match may be generated.

  If the two networks match (S122: YES), it is determined that the information processing apparatus 100 can execute communication with the communication target device via the specific network. Therefore, since it is not necessary to perform processing for newly establishing a communication path, the process proceeds to S139. On the other hand, if the two networks do not match (S122: NO), the process proceeds to S123.

  In S123, the application 121 receives the designated SSID from the communication target device via the NFC wireless communication 153. The designated SSID is an SSID designated by the communication target device. The designated SSID is an SSID used to execute communication with the communication target device using the wireless LAN_I / F 105.

  In S124, the application 121 determines whether or not the designated SSID received from the communication target device is a one-time SSID. The one-time SSID is an SSID having a different character string each time it is issued. The one-time SSID is an SSID for performing the above-described WFD wireless communication. As an example of a method for discriminating whether or not the designated SSID is a one-time SSID, a method for determining whether or not a predetermined character string indicating a one-time SSID is included in the character string of the designated SSID. Is mentioned. An example of the predetermined character string is a character string such as “onetime”.

  If the designated SSID is not a one-time SSID (S124: NO), it can be determined that the communication target device has designated infrastructure mode wireless LAN communication via the access point. Accordingly, the process proceeds to S126, and infrastructure mode wireless LAN communication is executed based on the received designated SSID.

  On the other hand, if the designated SSID is a one-time SSID in S124 (S124: YES), it is determined that the communication target device has designated WFD wireless communication, and the process proceeds to S128. In S128, the application 121 determines whether or not a specific network has been set. This determination may be made by confirming whether or not the SSID 603 is stored in the table TB1. If the specific network has not been set (S128: NO), the process proceeds to S136, and if the specific network has been set (S128: YES), the process proceeds to S130. In S130, the application 121 temporarily stores the SSID 603 of the specific network in the RAM 108. In the example of the present embodiment, the SSID of the network N2 (that is, SSID-2) is temporarily stored in the RAM 108.

  In S132, the application 121 determines whether the specific device is different from the communication target device. This determination may be made based on whether or not the specific device identification information 600 stored in the table TB1 matches the communication target device identification information received in S121. If the specific device matches the communication target device (S132: NO), the process proceeds to S136, and if different (S132: YES), the process proceeds to S134. In S <b> 134, the application 121 temporarily stores the specific device identification information 600 in the RAM 108.

  In step S136, the application 121 performs communication with the communication target device by WFD wireless communication. Specifically, the application 121 provides the OS 124 with the one-time SSID received in S123, and executes WFD wireless communication using the wireless LAN_I / F 105 with the communication target device. In the example of this embodiment, WFD wireless communication 155 is executed with the MFP 51 that is a communication target device.

  In S138, the application 121 changes the display of the communication partner network. In the example of the present embodiment, the display content shown in the region R2 in FIG. 5 is displayed at the display position of the region R1 instead of the display content shown in the region R1 in FIG. As a result, the display of the network of the communication partner is changed to the model number of the communication target device (that is, the MFP 51).

  In S139, the application 121 determines whether the specific device and the communication target device are different. Since the determination method is the same as the method used in S132 described above, description thereof is omitted. If they match (S139: NO), the process proceeds to S150, and if they are different (S139: YES), the process proceeds to S140. In S140, the application 121 changes the display of the communication partner device. In the example of the present embodiment, the display content shown in the region R2 in FIG. 5 is displayed at the display position of the region R1 instead of the display content shown in the region R1 in FIG. As a result, the display of the communication partner device is changed to the model number of the communication target device (that is, the MFP 51). Thus, information indicating the communication target device can be displayed on the display unit 102 during a period in which communication with the communication target device is performed using the wireless LAN_I / F 105.

  In S150, the application 121 transmits print data to the communication target device by communication using the wireless LAN_I / F 105. Since communication using the wireless LAN_I / F 105 is faster than communication using the NFC communication I / F 112, print data can be transmitted in a shorter time. In step S152, the application 121 determines whether transmission of print data has been completed. If transmission of the print data has not been completed (S152: NO), the process returns to S152, and if completed (S152: YES), the process proceeds to S154.

  In S154, the application 121 determines whether or not the one-time SSID switching process has been executed in a state where the specific network is set. The one-time SSID switching process is a process for switching the SSID used for executing communication using the wireless LAN_I / F 105 from the SSID of the specific network to the one-time SSID. This determination can be made based on whether or not the SSID of the specific network is temporarily stored in the RAM 108 (that is, whether or not the processing of S130 has been performed). When the one-time SSID switching process is executed in a state where the specific network is set (S154: YES), the process proceeds to S156.

In S156, the application 121 executes a return process. The return process is a process for returning the communication destination of the wireless communication using the wireless LAN_I / F 105 from the network including the communication target device to the specific network. Specifically, the application 121 returns the communication destination of the wireless communication using the wireless LAN_I / F 105 to the specific network by providing the OS 124 with the SSID of the specific network temporarily stored in the RAM 108. In the description example of the present embodiment, the wireless communication performed by the wireless LAN_I / F 105 is returned from the wireless communication 155 to the wireless communication 152. As a result, the communication destination of the wireless LAN_I / F 105 is changed from the network (that is, the network with the MFP 51 not via the first access point 501) including the communication target device (that is, the MFP 51) to the specific network (that is, the network N2). Returned.

  In step S157, the application 121 performs processing for restoring the network display of the communication partner. In the description example of the present embodiment, as shown in a region R1 in FIG. 5, the SSID (that is, SSID−) of the second access point 502 included in the specific network (that is, the network N2) is used as information indicating the communication partner network. 2) is displayed.

  In S158, the application 121 determines whether or not the communication device switching process has been executed. The communication device switching process is a process of switching a communication target device from a specific device to a communication target device. This determination can be made based on whether or not the specific device identification information 600 is temporarily stored in the RAM 108 (that is, whether or not the process of S134 has been performed). When the communication device switching process is being executed (S158: YES), the process proceeds to S162. In step S162, the application 121 performs processing for restoring the display of the communication partner device. In the explanation example of the present embodiment, as shown in an area R1 in FIG. 5, the model number of the specific device (that is, the MFP 52) is displayed as information indicating the communication partner device. Then, the flow ends.

  On the other hand, when the communication device switching process has not been executed (S158: NO), the process proceeds to S160. In step S160, the application 121 causes the display unit 102 to display information indicating that the communication partner device is not selected. Then, the flow ends.

  In S154, when it is determined that the one-time SSID switching process is not executed in a state where the specific network is set (S154: NO), the process proceeds to S172. In S172, the application 121 determines whether or not the one-time SSID switching process has been executed. This determination can be made based on whether or not the designated SSID received from the communication target device is a one-time SSID (that is, the determination result of S124).

  If the one-time SSID switching process is being executed (S172: YES), the process proceeds to S174, and the WFD wireless communication is disconnected. When the one-time SSID switching process is not executed (S172: NO), it is determined that the designated SSID received from the communication target device is the SSID for wireless communication in the infrastructure mode, and the process proceeds to S176. In S176, the application 121 stores the designated SSID in the table TB1 as the SSID 603 of the specific network. Then, the flow ends.

<Effect>
The effects of the application 121 described above will be described. In the application 121, when a specific network (for example, the network N2) set as a communication destination of communication using the wireless LAN_I / F 105 is different from a network (for example, the MFP 51) including the communication target device (for example, the MFP 51) ( In S122: NO), the designated SSID can be received from the communication target device via the NFC wireless communication 153 (S123). Based on the acquired designated SSID, communication (for example, wireless communication 155) with the communication target device (for example, MFP 51) can be executed using the wireless LAN_I / F 105 (S136). After the communication with the communication target device is completed (S152: Y), the communication destination using the wireless LAN_I / F 105 is changed from the network (for example, MFP 51) including the communication target device to the specific network (eg, MFP 51). Example: It is possible to automatically return to the network N2) (S156). Therefore, even when communication with a specific network (for example, network N2) using the wireless LAN_I / F 105 is started after communication with the communication target device using the wireless LAN_I / F 105 is completed, the wireless LAN_I / F 105 is used. It is possible to eliminate the need for the user to set the communication destination of the used communication. Therefore, user convenience can be improved.

  When the designated SSID is a one-time SSID (S124: Y), a communication path (eg, wireless communication 155) established with the communication target device (eg, MFP 51) using the wireless LAN_I / F 105 based on the designated SSID. Is a communication path that is highly likely to become unusable after communication is completed. The application 121 automatically returns the communication destination of communication using the wireless LAN_I / F 105 to the specific network (eg, network N2) after the communication with the communication target device ends (S152: Y) (S156). It is possible to avoid a situation in which a communication path that is likely to become unusable later continues to be used by the user.

  The application 121 can determine whether or not the network including the communication target device matches the specific network based on the match determination information received from the communication target device (S122). As a result, it is possible to cause the communication target device to make a match between both networks, and thus it is possible to reduce the processing load on the information processing apparatus 100.

  The application 121 can change the display of the communication partner's network and the display of the communication partner's device in response to connecting to a network different from the specific network (S136) (S138, S140). Further, in response to returning the communication destination to the specific network (S156), the display of the communication partner network and the display of the communication partner device can be returned (S157, S162). Thereby, since the communication target of the information processing apparatus 100 can be notified to the user in real time, the convenience for the user can be improved.

  When the specific network is not set (S128: N) and the specified SSID received from the communication target device is not a one-time SSID (S172: N), the specified SSID is set as the SSID 603 of the specific network as a table. It can be stored in TB1 (S176). Thereby, when the specific network is not set, the specific network can be automatically set. Therefore, it is possible to save the user from selecting and setting a specific network.

  The application 121 can detect the completion of communication using the wireless LAN_I / F 105 by detecting the completion of communication of image data (S152: Y). This eliminates the need to communicate information for determining the end of communication using the wireless LAN_I / F 105 with the communication target device, thereby reducing the amount of communication data. .

The application 121 provides the OS 124 with the one-time SSID received from the communication target device, thereby executing WFD wireless communication using the wireless LAN_I / F 105 with the communication target device (S136). In addition, the application 121 provides the OS 124 with the SSID temporarily stored in the RAM 108, so that the wireless LAN
The communication destination of the wireless communication using the _I / F 105 is returned to the specific network (S156). Accordingly, since the OS 124 can execute processing for performing communication, it is possible to suppress the processing amount executed by the application 121 and to suppress the capacity of the application 121.

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

<Modification>
The determination of matching between the network including the communication target device and the specific network is not limited to the form executed by the communication target device. FIG. 6 shows a part of the flow in the case where the matching determination is executed by the application 121. When the notification information is received from the OS 124 (S114: YES), the process proceeds to S115a. In S115a, the application 121 receives an SSID for identifying a network including the communication target device from the communication target device. In the example of this embodiment, the SSID (that is, SSID-1) of the network N1 that includes the MFP 51 that is the communication target device is received. In S117a, the application 121 determines whether or not the network including the communication target device matches the specific network. The determination is whether or not the SSID of the specific network (the SSID is read from the table TB1) and the SSID of the network to which the communication target device belongs (the SSID is acquired in S115a). May be performed. If both networks match (S117a: YES), the process proceeds to S139, and if both networks do not match (S117a: NO), the process proceeds to S118a. In S118a, the application 121 receives the designated SSID from the communication target device via the NFC wireless communication 153. As a result, it is possible for the application 121 to execute the matching determination.

  The determination as to whether or not the communication with the communication target device has ended is not limited to a mode in which it is determined in S152 whether or not the transmission of the print data has been completed. For example, the communication completion notification information indicating that the communication with the communication target device has been completed is received from the communication target device by communication using the wireless LAN_I / F 105, and the end of communication is detected. Also good. Accordingly, it is possible to reliably detect the end of communication with the communication target device using the wireless LAN_I / F 105.

  The timing at which the application 121 acquires the SSID of the network to which the information processing apparatus 100 is currently connected from the OS 124 is not limited to the timing at S116. For example, it may be acquired at the timing when the print preview is displayed or when the application 121 is activated.

  The processing of S122 and S124 can be omitted. In this case, the designated SSID is always handled as a one-time SSID. Therefore, WFD wireless communication is always used for communication with the communication target device.

  In the present embodiment, a mode has been described in which a user selects a device that has performed NFC communication while holding the information processing apparatus 100 as a communication target device, and causes the communication target device to execute print processing. As described above, when the printing process is executed using the NFC communication, the display unit 102 may display information for allowing the user to recognize that the printing process uses the NFC communication. For example, a character string indicating that printing is being performed by a device that holds the information processing apparatus 100 may be displayed on the display unit 102.

  The IP address values and SSID character strings used in the present embodiment are examples, and various values and character strings can be used.

  Communication between the first access point 501 and the MFP 51 and communication between the second access point 502 and the MFP 52 may be performed either wirelessly or by wire.

  The display example of the display unit 102 in FIG. 5 is an example. The display unit 102 may display images of various display forms.

  The model number 601 may be anything as long as it can distinguish between devices. For example, the model number 601 may not include a number, or may include only symbols. Also, a name such as a device name that can distinguish the device may be used instead of the model number.

  The information for identifying the device is not limited to the IP address 602, and a configuration using a URL or a MAC address may be used.

  The information processing apparatus 100 may be configured to connect an external memory such as a memory card. In place of the storage unit 109, various data may be stored in an external memory.
