JP 2007-166538 A

  When printing data to be printed by a printer, print settings such as paper size are required. Among print settings, for example, the paper size differs in the usable range depending on the type of printer, that is, the printer capability. For example, A3 cannot be set as the paper size for a printer that cannot use the A3 paper size.

  By the way, in printing that uses short-range wireless communication as a trigger as in Patent Document 1, for the convenience that printing can be started simply by bringing the transmission source device of the print target data closer to the printer, which printer is usually approached. The default print settings and the print settings used at the previous printing are used so that printing can be started. However, there is a possibility that the paper size set as the print setting cannot be used by the printer as the partner apparatus at this time, resulting in an inconvenience such as an error.

  The present invention has been made in view of the above-described circumstances, and provides an information processing program and an information processing apparatus that can suitably suppress the occurrence of errors based on print settings in printing that triggers short-range wireless communication. Objective.

  In order to achieve this object, an information processing program according to the present invention includes a first communication unit that communicates with an external device through first wireless communication using a short-range wireless communication method, and a wireless communication method different from the short-range wireless communication method A program executable by the control unit of an information processing apparatus including a second communication unit that communicates with an external device by second wireless communication according to a storage unit, a display unit, and a control unit, When the first wireless communication with the device is performed, the second wireless communication with the external device is performed based on the wireless information stored in the storage unit for performing the second wireless communication with the external device. A communication control means for starting communication establishment processing for establishing communication, and for accepting settings used for predetermined processing to be executed by the external device after completion of the communication establishment processing while the communication establishment processing is being performed; Configuration First display means for displaying a screen on the display unit, accepting means for accepting settings used for the predetermined process via the setting screen displayed by the first display means, and completion of the communication establishment process The control unit is configured as a first instruction output unit that outputs an instruction to execute the predetermined process based on the setting received by the receiving unit to the external device through the second wireless communication established by the communication establishment process. Make it work.

  The present invention can be configured in various modes such as an information processing device, a control device that controls the information processing device, an information processing system, an information processing method, and a recording medium that records an information processing program.

  According to the information processing program of claim 1, when the first wireless communication is performed with the external device by the short-range wireless communication method, the wireless communication different from the short-range wireless communication method is performed with the external device. Communication establishment processing for establishing the second wireless communication by the method is performed. While the communication establishment process is being performed, a setting screen for accepting settings used for a predetermined process to be executed by the external device after the communication establishment process is completed is displayed. Accordingly, it is possible to appropriately set the setting used for the predetermined process so as not to cause an error via the setting screen using the communication establishment process. Therefore, in printing that triggers short-range wireless communication, it is possible to suitably suppress the occurrence of errors based on print settings. In addition, since the setting used for the predetermined process can be set during the communication establishment process, the predetermined process using the setting can be quickly executed after the communication establishment process is completed.

  According to the information processing program of claim 2, in addition to the effect of claim 1, the following effect is obtained. When the first wireless communication is performed with the external device, information for specifying a setting value that can be set in the external device is acquired by the first wireless communication. Based on the setting value that can be set in the external device in which the first wireless communication is performed, specified by the acquired information, among the setting values that are stored in the storage unit and used as a setting for a predetermined process, It is determined whether there is a setting value that cannot be used by the external device. When it is determined that there is a setting value that cannot be used, a setting screen that includes the setting item corresponding to the target setting value is displayed. Therefore, since the setting value that cannot be used by the external device can be changed to an appropriate setting value on the setting screen, it is possible to suitably suppress the occurrence of an error based on the print setting.

  According to the information processing program of claim 3, in addition to the effect of claim 2, the following effect is obtained. When it is determined that there is no setting value that cannot be used by the external device, it is not necessary to change the setting value. Therefore, in such a case, an instruction to execute a predetermined process based on the setting value stored in the storage unit is output to the external device on the condition that the communication establishment process is completed without displaying the setting screen. Therefore, it is possible to prevent the setting value from being erroneously changed by displaying the setting screen even though the setting value does not need to be changed.

  According to the information processing program of claim 4, in addition to the effect of any one of claims 1 to 3, the following effect is provided. If the change in the setting stored in the storage unit received via the setting screen is a change that requires communication by the second wireless communication with a second external device different from the external device, the external device After the communication establishment process for establishing the second wireless communication between the information processing apparatus and the information processing apparatus is completed, an instruction to cancel the second wireless communication is output to the external apparatus through the established second wireless communication. Therefore, even if the first wireless communication between the two becomes impossible due to the information processing device being separated from the external device, the external device is established with the information processing device. The second wireless communication can be canceled. Thereby, it is possible to prevent an information processing apparatus that does not need to communicate immediately by the second wireless communication from wasting the number of apparatuses that can be connected at the same time by an external apparatus.

  According to the information processing program of the fifth aspect, in addition to the effect produced by the fourth aspect, the following effect is produced. When the change in the setting stored in the storage unit received via the setting screen is a change that requires communication by the second wireless communication with a second external device different from the external device, If communication by the first wireless communication is possible with the information processing device, an instruction to cancel the second wireless communication between the external device and the information processing device is transmitted to the external device by the first wireless communication. . Therefore, the second wireless communication can be canceled immediately without waiting for the external device to establish the second wireless communication with the information processing apparatus.

  According to the information processing program of the sixth aspect, in addition to the effect produced by any one of the first to fifth aspects, the following effect is produced. When the setting screen is displayed while the communication establishment process is being performed, a first operator for instructing completion of acceptance of the setting via the setting screen is displayed together with the setting screen. If an operation on the first operator is received before the communication establishment process is completed, an execution instruction for a predetermined process based on the received setting is output to the external device on the condition that the communication establishment process is completed. The Therefore, before the communication establishment process is completed, the accepted setting can be confirmed according to the operation on the first operator.

  According to the information processing program of claim 7, in addition to the effect of claim 6, the following effect is obtained. When the communication establishment process is completed without accepting an operation for the first operator, a second operator for instructing output of an execution instruction is displayed instead of the first operator. On the condition that an operation for the second operator is accepted, an instruction to execute a predetermined process based on the accepted setting is output to the external device. Therefore, since the second operator is displayed, it is possible to report that the communication establishment process has been completed and the execution instruction is waiting to be output.

  According to the information processing program of claim 8, in addition to the effect of claim 4 or 5, the following effect is obtained. When an operation for the first operator is accepted before the communication establishment process is completed, a third operator for instructing cancellation of the setting acceptance completion instruction is displayed instead of the first operator. . If an operation for the third operator is received before the communication establishment process is completed, the first operator is displayed instead of the third operator. Therefore, the setting can be changed again even after the first operator is operated.

  According to the information processing apparatus of the ninth aspect, the same effect as the information processing program of the first aspect is obtained.

The short-range wireless communication performed by the short-range communication unit 22 of the present embodiment is non-contact communication (hereinafter referred to as “NFC communication”) according to the NFC standard. That is, in the present embodiment, the terminal 10 can perform NFC communication with the MFP 100 having the short-range communication unit 122.

  The wireless communication unit 23 is an interface for performing communication based on the wireless LAN standard (wireless LAN communication). In the present embodiment, the wireless LAN communication performed by the wireless communication unit 23 is wireless communication based on a wireless LAN conforming to the IEEE802.11b / g / n standard. As described above, the terminal 10 communicates with the MFP 100 having the wireless communication unit 123 via the wireless communication unit 23 based on the Wi-Fi Direct standard (hereinafter, this communication is referred to as “WIDI communication”).

To convert to

  FIG. 2 is a diagram schematically illustrating an example of transition of a screen displayed on the LCD 16 by the application 12b of the present embodiment. When a print target file is selected on a target selection screen (not shown) displayed on the LCD 16 by the application 12b, a preview screen 50 is displayed. The preview screen 50 displays an image 51 based on the print target file selected on the target selection screen.

  According to the application 12b of this embodiment, when the print target file is a PDF file, an image based on the JPEG file converted from the PDF file by the conversion server 200 is the image 51. Is displayed. Specifically, the PDF format file selected as the file to be printed and the NFC print setting currently set in the terminal 10 (hereinafter, this print setting is referred to as “current NFC print setting”). Is uploaded to the conversion server 200, and the PDF file is converted into a JPEG file according to the current NFC print setting by the conversion server 200. Then, an image based on the converted JPEG file downloaded from the conversion server 200 is displayed as the image 51.

  When NFC communication is established between the terminal 10 and the MFP 100 while the preview screen 50 is displayed on the LCD 16, handover processing is started along with establishment of NFC communication. With the establishment of NFC communication, the screen displayed on the LCD 16 is switched from the preview screen 50 to another screen. The screen after the switching is used for the current NFC print setting, more specifically, the previous NFC printing. The print settings differ depending on whether or not the MFP 100 that is the partner of NFC communication can use the print settings.

  Specifically, when the current NFC print setting is a setting that can be used by MFP 100 that is the partner of NFC communication (that is, a setting that matches), NFC communication has been established between terminal 10 and MFP 100. Accordingly, the screen displayed on the LCD 16 is switched from the preview screen 50 to a screen (not shown) including a progress display indicating the progress of the handover process. Then, the screen including the progress display is switched to a printing screen 80 indicating that NFC printing is being performed with the completion of the handover process.

  On the other hand, if the current NFC print setting includes a setting that cannot be used by the MFP 100 that is the partner of the NFC communication (that is, an incompatible setting), NFC communication has been established between the terminal 10 and the MFP 100. Accordingly, the screen displayed on the LCD 16 is switched from the preview screen 50 to the setting screen 60, more specifically, the screen 60a.

  The setting screen 60 is a screen for changing settings that cannot be used in the MFP 100 among the current NFC print settings. The setting screen 60 displays a setting 61 that cannot be used by the MFP 100 among the current NFC print settings. In the example shown in FIG. 2, only the setting for whether or not to perform borderless printing is displayed as the setting 61. Is displayed.

  When a tap operation is performed on the setting 61 displayed on the setting screen 60, setting value candidates that can be set for the tapped setting 61 are displayed on the LCD 16 as options (not shown). The user can change the setting value in the setting by selecting a desired setting value from the options. Note that the setting value options are in accordance with the capability (so-called specifications) of the MFP 100 as the counterpart.

  An OK button 62 is displayed on a screen 60 a that is one form of the setting screen 60. The OK button 62 is a button for instructing confirmation of setting values in the setting 61 including those changed after the setting screen 60 is displayed without waiting for completion of the handover process. When a tap operation is performed on the OK button 62 during execution of the handover process, the screen displayed on the LCD 16 is switched from the screen 60 a to the standby screen 70.

  The standby screen 70 is a screen for waiting for completion of the handover process. Note that the setting value in the setting 61 cannot be changed on the standby screen 70. On the standby screen 70, a Cancel button 71 and a progress display 72 are displayed. The progress display 72 is a display showing the progress status of the handover process.

  The Cancel button 71 is a button for instructing to cancel the current setting value in the setting 61. If a tap operation is performed on the Cancel button 71 before the handover process is completed, the screen displayed on the LCD 16 is switched from the standby screen 70 to the screen 60a which is the setting screen 60 again. Thereby, the user can change the setting value in the setting 61 again.

  On the other hand, when the handover process is completed without performing the tap operation on the Cancel button 71, the setting value after the change in the setting 61 is converted by the conversion server 200, for example, switching whether or not borderless printing is performed. The NFC printing of the image 51 is executed using the current NFC print setting that reflects the changed setting value. In such a case, the screen displayed on the LCD 16 is switched from the standby screen 70 to the printing screen 80.

  Although details will be described later, if the setting value after the change in the setting 61 requires conversion in the conversion server 200, NFC printing is once canceled. For example, when the file to be printed has a file format that requires conversion by the conversion server 200, if the paper size is changed, conversion by the conversion server 200 is required. Therefore, in such a case, NFC printing is once canceled. Although not shown, if the setting value after the change in the setting 61 needs to be converted by the conversion server 200, an error screen (FIG. 5) prompting the user to establish NFC communication with the MFP 100 again after the conversion is completed. (Not shown) is displayed.

  When the handover process is completed without performing the tap operation on the OK button 62 displayed on the screen 60a (setting screen 60), the screen displayed on the LCD 16 is switched from the screen 60a to the screen 60b. The screen 60b is also a screen of one form of the setting screen 60. Therefore, the setting value in the setting 61 can be changed on the screen 60b.

  A print button 63 is displayed on the screen 60b. The print button 63 is a button for instructing confirmation of setting values for the setting 61 including those changed after the setting screen 60 is displayed. When a tap operation is performed on the print button 63, the current NFC print setting in which the changed setting value is reflected on condition that the changed setting value in the setting 61 does not require conversion in the conversion server 200. Is used to perform NFC printing of the image 51. In such a case, the screen displayed on the LCD 16 is switched from the screen 60b to the printing screen 80.

  Therefore, before the handover process is completed, the setting value in the setting 61 can be confirmed by performing a tap operation on the OK button 62. On the other hand, when the handover process is completed without performing the tap operation on the OK button 62, the setting value in the setting 61 can be confirmed by performing the tap operation on the print button 63.

  FIG. 3 is a flowchart showing the NFC printing process. This process is started when the application 12b receives an NFC event from the OS 12a with the preview screen 50 opened. The NFC event is an event that the OS 12a notifies the application 12b when the terminal 10 (the near field communication unit 22) detects a device (hereinafter referred to as “NFC device”) such as the MFP 100 that is a communication partner of NFC communication. is there. As the terminal 10 detects the NFC device, NFC communication is established between the terminal 10 and the detected NFC device. In this embodiment, the NFC device is the MFP 100.

  The CPU 11 requests the MFP 100 for an SSID (Service Set Identifier) for WIDI communication through NFC communication, whereby an SSID for WIDI communication (hereinafter simply referred to as “SSID”) and a password corresponding to the SSID. Are acquired from the MFP 100 by NFC communication (S301).

  In step S <b> 301, the CPU 11 requests the communication partner MFP 100 for model information through NFC communication, and thereby acquires the model information from the MFP 100 through NFC communication. The CPU 11 stores the SSID and password acquired from the MFP 100 and the model information in the RAM 13.

  The CPU 11 starts a handover process, that is, a process for establishing WIDI communication between the terminal 10 and the MFP 100 (S302). Specifically, the CPU 11 performs the handover process by setting the SSID and password acquired in S301 and stored in the RAM 13 as communication settings used when the wireless communication unit 23 communicates. Note that the handover process started in S302 requires a certain amount of time (for example, about 30 seconds) to complete.

  The CPU 11 determines whether the current NFC print setting can be used (S303). Specifically, the CPU 11 can acquire information indicating the capability of the MFP 100 as the communication partner based on the model information acquired in S301 and stored in the RAM 13, and can use the current NFC print setting based on the acquired information. Determine whether.

  The process of S303 will be described in more detail. When information indicating the capability of the MFP 100 corresponding to the model information is stored in the application storage area 12c, the CPU 11 acquires the corresponding information from the application storage area 12c. On the other hand, when the information indicating the capability of the MFP 100 corresponding to the model information is not stored in the application storage area 12c, the CPU 11 requests the communication partner MFP 100 for information indicating the capability by NFC communication. Information indicating the capability is acquired from MFP 100 by NFC communication.

  Alternatively, a management server (not shown) on a LAN (not shown) or a management server (not shown) on the Internet 800 is connected via the AP 50, and model information is handled from these management servers. The configuration may be such that information indicating the capability of the MFP 100 is acquired.

  Next, the CPU 11 determines, for each setting item of the current NFC print setting, whether or not the current setting value is included in setting values that can be set in the MFP 100 that are specified by the information indicating the acquired capability. When the CPU 11 determines that the setting value of the current NFC print setting for all the setting items is included in the setting values that can be set in the MFP 100 specified by the information indicating the acquired capability, This indicates that the current NFC print setting can be used for the capability of the MFP 100. That is, in such a case, the CPU 11 affirms the determination in S303.

  On the other hand, when the CPU 11 determines that the setting value of the current NFC print setting for at least one setting item is not included in the setting value that can be set in the MFP 100 specified by the information indicating the acquired capability, CPU11 denies judgment of S303.

  When the CPU 11 denies the determination of S303, that is, when the current NFC print setting cannot be used (S303: No), the CPU 11 switches the screen displayed on the LCD 16 to a setting screen for setting the NFC print setting ( S304). In the present embodiment, the CPU 11 displays, as a setting screen, a screen for changing settings that cannot be used by the MFP 100 among the current NFC print settings, for example, the setting screen 60 of FIG.

  The CPU 11 displays an OK button (for example, an OK button 62) for confirming the setting on the setting screen on the setting screen (S305). The CPU 11 determines whether a setting change via the setting screen has been accepted (S306). When the CPU 11 determines that the setting change has been received (S306: Yes), the CPU 11 stores the setting change, that is, the setting value after the change in the RAM 13 in association with the setting item (S307), and the process proceeds to S308. To do. The setting value options that can be set on the setting screen are in accordance with the capability of MFP 100 as the communication partner. On the other hand, when the CPU 11 determines that the setting change is not accepted (S306: No), the CPU 11 shifts the process to S308.

  The CPU 11 determines whether an operation for the OK button has been accepted (S308). When the CPU 11 determines not to accept the operation for the OK button (S308: No), the CPU 11 determines whether the handover process started in S302 is completed (S318).

  In step S318, the CPU 11 makes an inquiry to the MFP 100 using the SSID and password set when starting the handover process, and determines whether the handover process is completed according to a reply to the inquiry. Specifically, when the CPU 11 receives a reply to the inquiry, the CPU 11 determines that the handover process has been completed. If the CPU 11 determines in S318 that the handover process has not been completed (S318: No), the CPU 11 shifts the process to S306.

  In S308, when the CPU 11 determines that an operation for the OK button is accepted, that is, when an operation for the OK button is performed before the handover process is completed (S308: Yes), the process proceeds to S309.

  If the CPU 11 determines in S318 that the handover process is completed, that is, if the handover process is completed before the operation on the OK button is performed (S318: Yes), the CPU 11 replaces the OK button with the setting screen. A print button (for example, the print button 63) for confirming the setting is displayed on the setting screen (S319). The CPU 11 determines whether an operation for the print button has been accepted (S320).

  If the CPU 11 determines not to accept an operation for the print button (S320: No), it is determined whether a setting change via the setting screen has been accepted (S321). When the CPU 11 determines that the setting change has been received (S321: Yes), the CPU 11 stores the changed setting value in association with the setting item in the RAM 13 (S322), and moves the process to S320, as in S307. . On the other hand, when the CPU 11 determines that the setting change is not accepted (S321: No), the CPU 11 shifts the process to S320.

  When the CPU 11 determines that an operation for the print button has been received (S320: Yes), the CPU 11 shifts the processing to S309. Therefore, when the handover process is completed before the operation for the OK button is performed, the setting can be changed after the handover process is completed until the operation for the print button is performed. Then, on condition that either the OK button or the print button is operated, the CPU 11 shifts the process to S309.

  The CPU 11 determines whether the setting value after the change needs to be converted by the conversion server 200 in accordance with the change of the setting (S309). An example of the case where conversion by the conversion server 200 is required in accordance with the change of the setting is a case where the paper size is changed for a file to be printed in a file format that requires conversion by the conversion server 200. Note that, even after the setting is changed, if the data can be enlarged or reduced, the conversion server 200 may be configured not to require conversion.

  When the CPU 11 determines that conversion by the conversion server 200 is not required (S309: No), the CPU 11 determines whether the handover process is completed (S310) as in S318. If the CPU 11 determines in S310 that the handover process has not been completed (S310: No), the CPU 11 switches the screen displayed on the LCD 16 to a standby screen (for example, the standby screen 70) that waits for the completion of the handover process. (S311). The CPU 11 displays a progress display (for example, progress display 72) and a cancel button (for example, the cancel button 71) on the standby screen (S312 and S313).

  After the process of S313, the CPU 11 determines whether the handover process is completed as in S318 (S314). If the CPU 11 determines in S314 that the handover process has not been completed (S314: No), the CPU 11 determines whether an operation for the cancel button has been received (S327).

  When the CPU 11 determines that an operation for the cancel button is not accepted (S327: No), the CPU 11 shifts the process to S314. On the other hand, when the CPU 11 determines that an operation for the cancel button has been received (S327: Yes), the CPU 11 proceeds to S304 and switches the screen displayed on the LCD 16 to the setting screen. Therefore, if an operation on the cancel button is performed before the handover process is completed, the setting screen is displayed, so that the setting can be changed again.

  When the CPU 11 determines that the handover process is completed in S314, that is, when the handover process is completed with the standby screen displayed (S314: Yes), the CPU 11 displays the screen to be displayed on the LCD 16 as a printing screen. For example, the screen is switched to the printing screen 80 in FIG. 2 (S315). The CPU 11 executes the printing process (S316) and ends this process. Therefore, if the operation on the OK button is performed before the handover process started in S302 is completed, then the printing process (S316) is executed on the condition that the handover process is completed.

  In the printing process (S316), the CPU 11 transmits the printing data and the printing instruction to the MFP 100 by WIDI communication established by the handover process. As a result of the printing process (S316), the MFP 100 executes printing according to the received printing data using the printing function.

  In the present embodiment, the print target file or the image file converted from the print target file by the conversion server 200 and the current NFC print setting are transmitted to the MFP 100 as print data. Note that print data is generated from the print target file or the image file converted from the print target file by the conversion server 200 and the current NFC print settings, and the generated print data is transmitted to the MFP 100. It is good also as a structure.

  The “current NFC print setting” transmitted to the MFP 100 in the printing process (S316) is the NFC print setting stored in the application storage area 12c and the changed setting stored in the RAM 13 in S307 or S322. It reflects the set value. Note that the settings transmitted to the MFP 100 in the printing process (S316) are stored in the application storage area 12c as the print settings used in the previous NFC printing.

  In S310, when the CPU 11 determines that the handover process is completed (S310: Yes), the CPU 11 shifts the process to S315. Therefore, when an operation on the print button is performed, the CPU 11 affirms the determination in S310, and thus the print process (S316) is executed with the operation on the print button as a trigger.

  When the CPU 11 affirms the determination of S303, that is, when the current NFC print setting can be used (S303: Yes), the CPU 11 determines whether the handover process has been completed (S317) as in S318. The CPU 11 repeats the determination in S317 until the handover process is completed (S317: No).

  If the CPU 11 determines that the handover process has been completed (S317: Yes), the CPU 11 shifts the process to S315. Therefore, according to the processing of S303 and S317, the setting screen is not displayed when the current NFC print setting can be used. Therefore, it is possible to prevent an incorrect setting from being changed due to the display of the setting screen even though it is not necessary to change the setting.

  If the CPU 11 determines that conversion by the conversion server 200 is required in S309 (S309: Yes), it determines whether NFC communication with the MFP 100 is possible (S323). The determination is affirmed that NFC communication is possible, for example, when the CPU 11 transmits data for communication confirmation by NFC communication and receives a reply.

  When the CPU 11 denies the process of S323, that is, when NFC communication cannot be performed with the MFP 100 (S323: No), the CPU 11 determines whether the handover process is completed as in S318 (S324). The CPU 11 repeats the determination in S324 until the handover process is completed (S324: No). If the CPU 11 determines that the handover process has been completed (S324: Yes), the CPU 11 shifts the process to S325.

  On the other hand, when the CPU 11 affirms the process of S323, that is, when NFC communication with the MFP 100 is possible (S323: Yes), the CPU 11 shifts the process to S325 regardless of the status of the handover process. That is, even if the handover process is not completed, the CPU 11 shifts the process to S325.

  In step S325, the CPU 11 transmits an instruction to cancel the WIDI communication to the MFP 100. More specifically, when the CPU 11 affirms the process of S323, the CPU 11 transmits the instruction to the MFP 100 through NFC communication. On the other hand, when the CPU 11 denies the process of S323, the CPU 11 transmits the instruction to the MFP 100 by WIDI communication established by the handover process. As a result of the process of S325, the MFP 100 cancels the WIDI communication with the terminal 10.

  In many cases, there is an upper limit on the number of devices that the MFP 100 can perform WIDI communication at the same time. Since conversion by the conversion server 200 takes a certain amount of time (for example, about several minutes), if the WIDI communication between the terminal 10 and the MFP 100 is kept connected during that time, another device is connected to the MFP 100 and the WIDI. There may be situations where communication becomes impossible. On the other hand, according to the processing of S309 and S323 to S325, when conversion in the conversion server 200 is required due to the change in setting, an instruction to cancel WIDI communication is transmitted to the MFP 100 of the communication partner. . Therefore, it is possible to prevent the terminal 10 from wasting the number of devices that can be connected to the MFP 100 at the same time.

  In particular, when the terminal 10 can perform NFC communication with the MFP 100, an instruction to cancel WIDI communication is transmitted using NFC communication. Therefore, the WIDI communication can be canceled at an early stage regardless of the status of the handover process. On the other hand, if the terminal 10 cannot perform NFC communication with the MFP 100, the terminal 10 waits for completion of the ongoing handover process, and transmits an instruction to cancel the WIDI communication using the WIDI communication established by the handover process. The Therefore, when the terminal 10 establishes NFC communication as a trigger for NFC printing and then the terminal 10 is separated from the MFP 100, a situation in which NFC communication cannot be performed between the terminal 10 and the MFP 100 occurs. Even so, the instruction can be transmitted to the MFP 100.

  After the process of S325, the CPU 11 switches the screen displayed on the LCD 16 to an error screen (S326), and ends this process. The error screen is a screen prompting to establish NFC communication with the MFP 100 again after the conversion in the conversion server 200 is completed. So you can tell what to do after that.

  According to the present embodiment, the setting screen is displayed during the handover process started based on the establishment of the NFC communication between the terminal 10 and the MFP 100. The NFC print settings can be changed as appropriate. Therefore, in NFC printing, the print setting transmitted from the terminal 10 cannot be used by the MFP 100, and an event in which an error occurs can be suitably suppressed. In addition, since the setting screen is displayed during the handover process, the NFC print setting can be set to an appropriate value during the period. Therefore, after completion of the handover process, it is possible to quickly execute NFC printing using an appropriately set NFC print setting.

  In particular, since a screen for changing settings that cannot be used in MFP 100 among the current NFC print settings is displayed as the setting screen, it is easy to grasp which setting should be changed. In addition, setting values that cannot be used in MFP 100 can be changed to appropriate setting values. Therefore, it is possible to suitably suppress the occurrence of errors based on the print settings.

  In addition, an OK button is displayed on the setting screen before the handover process is completed, and a print button is displayed on the setting screen after the handover process is completed. That is, before and after the handover process is completed, the mode of the buttons displayed on the setting screen for confirming the setting on the setting screen is different. Therefore, the status of the handover process can be reported according to the mode of the button displayed on the setting screen. That is, when the OK button is displayed, it can be reported that the handover process is still being performed. On the other hand, when the print button is displayed, it can be reported that the handover process has been completed and the print process is waiting to be executed.

  In each of the embodiments described above, MFP 100 having a plurality of functions such as a print function is illustrated as an external device, but a printer having only a print function can also be adopted as an external device. In the above-described embodiment, the present invention is applied when the terminal 10 uses the printing function of the MFP 100. However, the present invention is applied even when a function other than the printing function of the MFP 100 is used. Applicable. For example, the present invention may be applied when the terminal 10 uses the scan function of the MFP 100 by transmitting a scan execution instruction using NFC communication establishment as a trigger.

  In the above embodiment, the setting screen is displayed during the handover process for establishing WIDI communication between the terminal 10 and the MFP 100 with the establishment of NFC communication as a trigger. Instead, in the configuration in which Wi-Fi communication via the AP 50 is established between the terminal 10 and the MFP 100 using NFC communication establishment as a trigger, a setting screen is displayed during the process of establishing the Wi-Fi communication. It is good also as a structure which displays. In such a modification, the process of establishing Wi-Fi communication via the AP 50 between the terminal 10 and the MFP 100 is an example of the “communication establishment process”.

  In the above-described embodiment, the setting screen is configured to display a screen for changing settings that cannot be used in the MFP 100 among the current NFC print settings. Instead of this, not only settings that cannot be used in the MFP 100 but also a screen on which all NFC print settings can be set may be displayed as a setting screen. According to such a configuration, the number of copies to be printed can be changed during the handover process.

  In S <b> 301 in the NFC printing process (FIG. 3) of the above embodiment, the terminal 10 acquires the SSID and password from the MFP 100.
