When the user selects a desired device from the device list via the operation unit 112, the information processing apparatus 110 accesses a position information setting screen 903 provided by the control unit 141 of the selected image forming apparatus 140. The device search screen 902 has the same display format as the printer selection screen that is displayed even when the “print button” is pressed. However, the device search screen according to the second embodiment is assumed to be a screen that is displayed in response to pressing of a “button for setting position information in the image forming apparatus” or “search button for image forming apparatus”. Of course, a position information setting screen (to be described later) may be displayed by pressing the “print button”, but the usability when the user uses the print function is lowered. Preferably, printing and position information setting are separated.

  In this embodiment, an example in which a device called MF8080 is selected is described. At this time, the control unit 141 of the image forming apparatus 140 checks whether the access permission query string received from the information processing apparatus 110 is valid. The control unit 141 responds to the information processing apparatus 110 with the location information setting screen 903 when the access permission query string is valid, and with the location information reference screen 904 when it is invalid. The display unit 113 displays a key for performing position information setting reference and position information setting execution on the position information setting screen 903.

  When the user presses the position information setting reference key via the operation unit 112, a position information reference screen 906 is returned to the information processing apparatus 110. When the user presses the position information setting execution key, the control unit 111 acquires position information by the GPS 228 and transmits the acquired position information to the image forming apparatus 140. The image forming apparatus 140 responds to the information processing apparatus 110 with a position information setting execution screen 905 that sets the received position information as the position information of the image forming apparatus and indicates the setting result. The display unit 113 displays only the position information setting reference key on the position information reference screen 904 displayed when the access permission information is invalid, and the user cannot execute the position information setting. In addition, although it was set as the position information setting screen in Example 2, it is not restricted to this form. For example, the position information setting may be added as one of the items of the remote UI for confirming the state of the image forming apparatus and / or confirming the job input to the image forming apparatus. In this case, the URL sent from the image forming apparatus is the URL of the remote UI. In addition, position information setting may be added as one of UI items dedicated to the driverless print service provided by the image forming apparatus. In this driverless print service, an information processing apparatus and an image forming apparatus perform wireless communication, and an information processing apparatus in which a driver for controlling the image forming apparatus is not installed transmits print data to the image forming apparatus. It is a service to print with. The UI dedicated to the driverless print service is a UI for confirming information related to the driverless print service as well as performing settings necessary for using the service.

  A processing flow until the information processing apparatus 110 according to the present exemplary embodiment searches for an image forming apparatus using mDNS and accesses the position information setting screen of the image forming apparatus 140 will be described with reference to FIG. In step S1001, the control unit 111 of the information processing apparatus 110 transmits mDNS service discovery with the multicast TTL setting set to 1. Since the reach of the multicast with the TTL setting set to 1 is limited to the local network, it can be estimated that the searched device is physically close to the information processing apparatus 110.

  In step S1002, the control unit 111 repeats transmission of mDNS service discovery for a certain period of time. In step S1003, the control unit 111 receives an mDNS service response. In that case, in S1004, the device name and admin key value are added to the device search result list. The control unit 111 repeats the processes of S1003 and S1004 for a predetermined time. When the predetermined time has elapsed, in step S1006, the control unit 111 determines whether one or more image forming apparatuses have been searched. When one or more image forming apparatuses 140 are searched, the control unit 111 displays the searched device name on the display unit 113 in step S1007. In step S1007, when the user selects a desired image forming apparatus 140 from the displayed device list, in step S1008, the control unit 111 accesses the administration corresponding to the device name selected by the user using a browser. When one or more image forming apparatuses are not searched in S1006, the control unit 111 of the information processing apparatus 110 displays a message indicating that no device is searched on the display unit 113 in S1009.

  With reference to FIG. 11, a device search result list managing the results of the device search performed by the information processing apparatus 110 according to this embodiment using mDNS will be described. In this example, MF8080 (1101), iRC3200 (1102), and LBP5910 (1103) are searched. The admin value that each image forming apparatus responds to as an mDNS response is also managed in this list. The subsequent processing in the second embodiment is the same as the processing in and after FIG.

Example 3
In the third embodiment, a configuration in which the information processing apparatus 110 notifies and sets position information of the image forming apparatus 140 by NFC will be described. The purpose of the second embodiment is that the image forming apparatus 140 acquires position information automatically and more accurately by acquiring position information from the information processing apparatus 110 by NFC. NFC is a short-distance wireless communication of a few tens of centimeters. Therefore, devices connected by NFC are guaranteed to be physically close to each other.

  The position information setting operation in the operation unit 142 of the image forming apparatus 140 according to the present exemplary embodiment will be described with reference to FIG. When the user selects position information setting on the system management setting screen 1201, the screen of the operation unit 142 transitions to the position information setting screen 1202. At this time, the control unit 141 of the image forming apparatus 140 puts the NFC interface 213 into a data reception waiting state. When the user touches the information processing apparatus 110 with the NFC reader of the image forming apparatus 140, the NFC interface 229 of the information processing apparatus 110 transmits the position information of the information processing apparatus 110 to the image forming apparatus 140 via NFC. Upon receiving the position information, the image forming apparatus 140 sets the transmitted position information as the position information of the image forming apparatus 140 and displays a position information setting screen 1203 on the operation unit 142. When the image forming apparatus 140 does not receive position information within a certain time, a position information setting failure screen 1204 is displayed on the operation unit 142.

  Next, an operation flow until the information processing apparatus 110 according to the present exemplary embodiment notifies and sets the position information of the image forming apparatus 140 by NFC will be described with reference to FIG.

  First, when the display unit 113 of the information processing apparatus 110 displays the position information setting screen 1301 of the image forming apparatus, the NFC interface 229 of the information processing apparatus 110 enters a position information transmission waiting state using NFC. When the user touches the information processing apparatus 110 with the NFC reader of the image forming apparatus 140, the NFC interface 229 of the information processing apparatus 110 transmits the position information of the information processing apparatus 110 to the image forming apparatus 140 via NFC. When the transmission using NFC is normally completed, the information processing apparatus 110 displays a position information setting screen 1302 on the display unit 113. If the transmission using NFC fails, the information processing apparatus 110 displays a position information setting failure screen 1303 on the display unit 113.

  Next, a processing flow in which the image forming apparatus 140 according to the present exemplary embodiment receives a position information setting request via NFC and sets position information will be described with reference to FIG. More specifically, the processing flow is executed by the image forming apparatus 140 when the user touches the information processing apparatus 110 with the NFC reader of the image forming apparatus 140 on the position information setting screen 1301 described with reference to FIG.

  In S1401, the NFC interface 213 waits for reception of NFC data for a predetermined time. The control unit 141 of the image forming apparatus 140 determines whether or not NFC data has been received in S1402 after receiving NFC data or after a predetermined time has elapsed. When determining that the NFC data has been received, the control unit 141 reads the latitude / longitude information from the received NFC data in S1403. In step S <b> 1404, the latitude / longitude information read by the control unit 141 is set as the position information of the image forming apparatus 140. In step S <b> 1405, the control unit 141 displays a position information setting screen 1302 on the operation unit 142. On the other hand, if it is determined in step S1402 that NFC data has not been received, the control unit 141 displays a position information setting failure screen 1303 on the operation unit 142 in step S1406. In the third embodiment, NFC has been described as an example of short-range wireless communication. However, the present invention is not limited to this, and any short-range wireless communication such as Bluetooth (registered trademark) or TransferJet may be used.

  According to the information processing apparatus described in the first, second, and third embodiments, the user can easily set the position information of the image forming apparatus in the image forming apparatus. When position information is set in the image forming apparatus, the physical location of the image forming apparatus can be known when the user searches for the image forming apparatus on the network using mDNS or the like. Accordingly, for example, if the information processing apparatus has a function of displaying an image forming apparatus on a map, a system for displaying the image forming apparatus searched on the map becomes possible, and a highly convenient printing system is provided. It becomes possible to do.
