An example in which the terminal device 30 executes wireless setting for performing will be described.

  As shown in FIG. 1, the printer 10 (an example of a device) includes a CPU 11, a ROM 12, a RAM 13, an NVRAM (nonvolatile memory) 14, a printing unit 15, a wireless LAN interface 16, a USB interface 17, a display unit 18, and an operation unit 19. It has.

  The ROM 12 and the NVRAM 14 store programs for executing various operations of the printer 10, and the CPU 11 controls each unit in accordance with the programs read from the ROM 12 and the NVRAM 14. The printing unit 15 prints an image on a sheet based on print data under the control of the CPU 11.

  The wireless LAN interface 16 is based on a wireless setting between an infrastructure mode in which communication is performed indirectly to other devices via the access point 50 and an ad hoc mode in which communication is performed directly without using the access point 50. Operates in one of the set modes. In addition, the NVRAM 14 can store various setting values set by wireless settings as will be described later, and the CPU 11 communicates with other devices through the wireless LAN interface 16 using these setting values. .

  A USB cable 60 connected to the terminal device 30 can be connected to the USB interface 17, thereby enabling communication between the printer 10 and the terminal device 30. The display unit 18 includes a display, a lamp, and the like, and displays images such as various setting screens and operation states of the apparatus. The operation unit 19 includes a plurality of buttons and accepts various instructions input by the user.

  The terminal device 30 (an example of a control device) is, for example, a portable computer, and includes a CPU 31, a ROM 32, a RAM 33, an HDD (hard disk drive) 34, a wireless LAN interface 35, a USB interface 36, a display unit 37, and an operation unit 38. I have.

  The ROM 32 stores a program such as BIOS. The HDD 34 (an example of a storage unit) stores an OS, a printer driver, a setting program 40 for executing wireless setting processing to be described later, and the like. The CPU 31 (an example of a specifying unit and a generation unit) controls each unit according to a program read from the ROM 32 or the HDD 34 onto the RAM 33.

  The wireless LAN interface 35 (an example of a receiving unit) includes an infrastructure mode in which communication is performed indirectly with another device via an access point, and an ad hoc mode in which communication is performed directly without using an access point. Operates in one mode set by wireless settings. The HDD 34 stores various setting values set by wireless settings, and the CPU 31 communicates with other devices through the wireless LAN interface 35 using these setting values.

  The USB cable 60 described above can be connected to the USB interface 36 (an example of an output unit and a transmission unit). The display unit 37 (an example of an output unit) includes a display and displays various images under the control of the CPU 31. The operation unit 38 (an example of a first reception unit and a second reception unit) includes a keyboard and a pointing device, and receives various instructions input by the user.

  The access point 50 includes a control unit 51, a RAM 52, an EEPROM 53, a wired LAN interface 54, and a wireless LAN interface 55. The EEPROM 53 stores firmware, setting values for wireless settings, and the like. The control unit 51 reads the firmware from the EEPROM 53 onto the RAM 52 and controls the operation of each unit.

  The wired LAN interface 54 is connected to the network line 61 via a wired LAN, and can communicate with a device (not shown) connected to the same network line 61. The wireless LAN interface 55 performs wireless communication by connecting to the printer 10 or the terminal device 30 provided with a wireless communication function. The access point 50 has a function of relaying data communication between devices connected to the wireless LAN interface 55 or the wired LAN interface 54.

  The access point 50 has an embedded web server function (EWS). For example, when the terminal device 30 is connected to the wired LAN interface 54 or the wireless LAN interface 55 and the address of the access point 50 is called by a web browser (an HTTP request is transmitted to the access point 50), the control unit 51 of the access point 50 A web page is generated from the web page data 58 stored in the EEPROM 53 and transmitted to the terminal device 30.

  Thereby, in the terminal device 30, the web page which shows the various information regarding the access point 50 can be displayed on the display part 37. FIG. For example, a wireless setting screen or a screen for displaying a wireless setting value (these screens are examples of a screen for confirming the wireless setting) can be displayed as a web page. By displaying the setting screen for wireless settings, the user can set the values of various setting items using the operation unit 38.

(Wireless setting process)
An operation of a wireless setting process for performing wireless setting for the printer 10 by the terminal device 30 will be described. 2 and 3 are flowcharts of the wireless setting process.

  In order to perform this wireless setting process, the user connects the printer 10 and the terminal device 30 in advance using the USB cable 60. Then, an instruction to execute the setting program 40 is input from the operation unit 38 of the terminal device 30. Upon receiving this execution instruction, the CPU 31 activates the setting program 40 and starts the wireless setting process.

  In the wireless setting process shown in FIG. 2, the CPU 31 first displays a selection screen on the display unit 37 for allowing the user to select whether to set the infrastructure mode or the ad hoc mode (S101). Here, in the infrastructure mode setting, the printer 10 performs settings for wireless communication with the access point 50, and in the ad hoc mode setting, the printer 10 performs settings for performing direct wireless communication with the terminal device 30. And

  When the selection for setting the infrastructure mode is input from the operation unit 38 (S101: YES), the CPU 31 transmits an instruction for causing the printer 10 to search for the access point 50 from the USB interface 36 (S102). Upon receiving this instruction, the CPU 11 of the printer 10 searches for a beacon signal transmitted from the access point 50 using the wireless LAN interface 16. When a beacon signal from the access point 50 is found, the MAC address of the access point 50 included in the signal is transmitted to the terminal device 30.

  When a plurality of access points are found in the printer 10, the access point information is transmitted to the terminal device 30 side, and the discovered access points are displayed on the display unit 37 of the terminal device 30 as a list. The user may be allowed to select one access point to which the printer 10 is connected.

  In addition, when the wireless LAN interface 36 of the terminal device 30 is set for wireless communication with the access point 50, the wireless LAN interface 36 receives information such as a MAC address directly from the access point 50. Also good.

  When receiving the MAC address of the access point 50, the CPU 31 acquires a vendor code (OUI: Organizationally Unique Identifier) included in the MAC address (S103). Here, the HDD 34 stores a first correspondence table 41 for setting the infrastructure mode that associates the vendor of the access point with the item name of the setting item included in the setting screen of the wireless setting of the access point.

  FIG. 4 is a diagram illustrating an example of the first correspondence table 41 for setting the infrastructure mode. In general, the item name displayed on the access point setting screen varies depending on the vendor of the access point. In other words, if the vendor is the same, the item names used on the setting screen are the same.

  In the first correspondence table 41, the vendor code of the MAC address, the vendor name, and item names indicating the setting items of “SSID”, “encryption key”, and “channel” are associated with each other. For example, the item name indicating the setting item of “encryption key” is written as “Passphrase” on the setting screen of “Company A” and “network key” on the setting screen of “B company”.

  Note that the setting items shown in the first correspondence table 41 in FIG. 4 are examples, and there are various other setting items for wireless settings such as “authentication method”, “encryption method”, and “IP address”. Such setting items can be included in the first correspondence table 41. Further, the first correspondence table 41 can include three or more types of vendor codes and vendor names, and item names corresponding thereto.

  After obtaining the vendor code from the MAC address in S103, the CPU 31 of the terminal device 30 determines whether the vendor code exists in the first correspondence table 41 (S104). When the vendor code exists in the first correspondence table 41 (S104: YES), the item name associated with the vendor code is acquired from the first correspondence table 41 (S105). Thereby, the item name included in the setting screen of the wireless setting of the access point 50 is specified.

  Here, the HDD 34 stores default value data 42 in which a default item name is associated with each setting item of the wireless setting. When the acquired vendor code does not exist in the first correspondence table 41 (S104: NO), the CPU 31 acquires a default item name from the default value data 42 (S106).

  Subsequently, the CPU 31 generates setting screen data (an example of image data) for displaying the setting screen 70 including the item name acquired in S105 or S106, and displays the setting screen data on the display unit 37 (S107).

  FIG. 5 shows an example of the setting screen 70. The setting screen 70 includes an SSID input unit 71 to which the value of the setting item “SSID” is input, an encryption key input unit 72 to which the value of “encryption key” is input, and a channel input unit 73 to which the value of “channel” is input. In addition, an OK button 74 for confirming the values input to the input units 71 to 73 is provided. Further, the setting screen 70 has item name display portions 75, 76, 77 indicating the item names of the respective setting items beside the input portions 71, 72, 73.

  The setting screen 70 of FIG. 5 shows a display example when the item name corresponding to the company A is acquired from the first correspondence table 41. That is, “SSID” is displayed on the item name display unit 75 of the SSID input unit 71, “Passphrase” is displayed on the item name display unit 76 of the encryption key input unit 72, and “Channel” is displayed on the item name display unit 77 of the channel input unit 73. Is displayed.

  When the item name corresponding to company B is acquired from the first correspondence table 41, “access point name”, “network key”, and “channel” are displayed in the item name display portions 75, 76, and 77, respectively. When the vendor code acquired from the access point 50 does not exist in the first correspondence table 41, the default item names are displayed in the item name display sections 75 to 77, respectively.

  Thus, the item name on the setting screen 70 is replaced with the vendor name acquired from the access point 50 and displayed. Thereby, the item name displayed on the wireless setting setting screen of the access point 50 is displayed as the item name on the wireless setting setting screen 70 of the printer 10, so that the user can easily grasp the meaning content. In some cases, the setting screen of the access point 50 can be displayed and the value to be set on the printer 10 side can be easily confirmed. Note that the setting items shown on the setting screen 70 are examples, and other setting items can be provided as appropriate.

  After displaying the setting screen 70 in S107 of FIG. 2, the CPU 31 inputs a value from the operation unit 38 to each of the input units 71 to 73, and when the OK button 74 is clicked, the input units 71 to 73 are displayed. The value input to is transmitted to the printer 10 as a setting value for wireless setting (S108). The CPU 11 of the printer 10 stores the received setting value in the NVRAM 14.

  Subsequently, the CPU 31 of the terminal device 30 transmits an instruction for causing the printer 10 to perform communication with the access point 50 (S109). Upon receiving this instruction, the CPU 11 of the printer 10 transmits a connection request from the wireless LAN interface 16 to the access point 50 using the setting value stored in the NVRAM 14. Based on the response from the access point 50, for example, whether the connection is successful or unsuccessful, whether the setting value on the printer 10 side matches the setting value on the access point 50 side, or the signal strength. Information is transmitted to the terminal device 30 as a communication result.

  Upon receiving the communication result from the printer 10, the CPU 31 of the terminal device 30 creates a report indicating information related to the communication result as print data (an example of image data), and outputs it to the printer 10 from the USB interface 36 (S110). This wireless setting process is terminated. The CPU 11 of the printer 10 receives this print data and prints a report on the sheet to the printing unit 15.

  FIG. 6 is a diagram illustrating an example of a report. In this report, a result (success or failure) 80 of wireless communication with the access point 50, a diagnosis result 81 diagnosed by the CPU 31 on the communication result, and a wireless setting (item name and its setting value) 82 are shown. . In the case of communication failure, the diagnosis result 81 indicates information such as a cause and a coping method, and the item name acquired in S105 or S106 as the item name 83 included therein (here, “Passphrase”). )It is shown.

  More specifically, the setting program 40 has a plurality of templates for displaying the diagnosis result, and the CPU 31 selects a template to be used from those templates according to the communication result received from the printer 10. At this time, when the item name of the setting item of the first correspondence table 41 is included in the selected template, the item name acquired as described above is inserted at the position indicating the item name 83.

  Therefore, if the vendor code of the access point 50 is different, the item name 83 of the diagnosis result 81 can be replaced with the item name corresponding to the vendor code and displayed accordingly. Similarly, in the wireless setting 82 of the report, some item names 84 and 85 are represented by the item names acquired in S105 or S106 (here, “SSID” “Channel”).

  As described above, the item names 83 to 85 included in the report can be represented by the item names displayed on the setting screen of the wireless setting of the access point 50, so that the user can easily grasp the contents.

  The CPU 31 ends the wireless setting process after outputting the report to the printer 10. When the communication between the printer 10 and the access point 50 is successful, the user disconnects the USB cable 60 that connects the printer 10 and the terminal device 30 and connects the printer 10 and the printer 10 via the access point 50 from the terminal device 30 or the like. Can communicate.

  Further, when selection for setting the ad hoc mode is input from the operation unit 38 in S101 (S101: NO), the CPU 31 executes an ad hoc setting process (S111). In this ad hoc setting process, since the printer 10 performs settings for directly communicating with the terminal device 30 wirelessly as described above, the access point 50 is not necessary. In the present embodiment, before setting the ad hoc mode for the printer 10, the wireless setting for connecting to the printer 10 in the ad hoc mode is performed for the wireless LAN interface 35 of the terminal device 30. .

  In the ad hoc setting process shown in FIG. 3, first, the CPU 31 inquires and acquires the OS name (including version) of the terminal device 30 and the vendor name of the wireless card configuring the wireless LAN interface 35 (S201). When the OS name or the wireless card vendor name cannot be acquired for some reason (S202: NO), a screen for allowing the user to input the OS name and the wireless card vendor name that cannot be acquired is displayed on the display unit 37. Then, the OS name or the vendor name input from the operation unit 38 is acquired (S203).

  Here, when performing wireless setting of the wireless LAN interface 35 on the terminal device 30, an OS standard setting program or a setting program corresponding to the wireless card is used. In general, the item names displayed on the wireless card setting screen are considered to differ depending on the type of OS and the vendor of the wireless card.

  The HDD 34 associates the OS type with the item name of the setting item included in the setting screen of the wireless setting of the terminal device 30 itself, and further associates the vendor of the wireless card with the item name of another setting item. A second correspondence table 43 for setting is stored.

  FIG. 7 is a diagram illustrating an example of the second correspondence table 43 for ad hoc setting. In the second correspondence table 43, three item names indicating three setting items “SSID”, “encryption key”, and “channel” are associated with each of the wireless card vendors “Company X” and “Company Y”. . Further, in the second correspondence table 43, the type of OS is associated with item names (ad hoc setting names) that collectively indicate the setting items of the ad hoc mode including the above three setting items.

  The CPU 31 determines whether the OS name and the wireless card vendor name are acquired from the OS in S201, or whether the acquired OS name exists in the second correspondence table 43 after acquiring from the user input in S203. (S204). If the OS name exists in the second correspondence table 43 (S204: YES), the item name corresponding to the OS name is acquired (S205). If the OS name does not exist in the second correspondence table 43 (S204: NO), the default item name is acquired from the default value data 42 (S206).

  Subsequently, the CPU 31 determines whether the vendor name of the wireless card acquired in the second correspondence table 43 exists (S207). If it exists (S207: YES), the item name corresponding to the vendor name is displayed. Obtain (S208). If the wireless card vendor name acquired in the second correspondence table 43 does not exist (S207: NO), the default item name is acquired from the default value data 42 (S209).

  And CPU31 produces | generates the setting screen data (an example of image data) which displays the setting screen 90 containing the item name acquired in S205 or S206, and the item name acquired in S208 or S209, The setting screen data Is displayed on the display unit 37 (S210).

  FIG. 8 shows an example of this setting screen 90. The setting screen 90 includes an SSID input unit 91 to which the value of the setting item “SSID” is input, an encryption key input unit 92 to which the value of “encryption key” is input, and a channel input unit 93 to which the value of “channel” is input. , OK buttons 94 for confirming values input to the input units 91 to 93 are provided. Further, the setting screen 90 has item name display portions 95, 96, and 97 indicating the item names of the respective setting items beside the input portions 91, 92, and 93. Furthermore, the setting screen 90 has an item name display section 98 that shows the item names of the entire setting items of the ad hoc mode.

  The setting screen 90 in FIG. 8 includes an item name corresponding to the OS “MAC OS XX” (MAC OS is a registered trademark) and an item name corresponding to the wireless card vendor “Y company” from the second correspondence table 43 in FIG. The example of a display when acquired is shown. That is, “name” is displayed on the item name display section 95 of the SSID input section 91, “security key” is displayed on the item name display section 96 of the encryption key input section 92, and “channel” is displayed on the item name display section 97 of the channel input section 93. Is displayed on the item name display section 98, and “computer to computer (setting)” is displayed.

  If the OS type of the terminal device 30 and the vendor of the wireless card are different, different item names can be displayed on the item name display sections 95 to 98 accordingly. As a result, the same item name as when the wireless setting of the wireless LAN interface 35 is performed by the terminal device 30 can be displayed on the setting screen 90, and the user can easily grasp the setting contents.

  After displaying the setting screen 90 in S210 of FIG. 3, the CPU 31 inputs a value from the operation unit 38 to each of the input units 91 to 93, and when the OK button 94 is clicked, each input from the USB interface 36. The values input to the units 91 to 93 are transmitted to the printer 10 as wireless setting values (S211), and this ad hoc setting process is terminated. The CPU 11 of the printer 10 stores the received setting value in the NVRAM 14.

  The CPU 31 thus completes the ad hoc setting process in S111 of FIG. 2, and then transmits an instruction for causing the printer 10 to perform communication with the terminal device 30 (S112). Upon receiving this instruction, the CPU 11 of the printer 10 transmits a connection request from the wireless LAN interface 16 to the terminal device 30 using the setting value stored in the NVRAM 14, and the CPU 31 of the terminal device 30 receives the connection request. Wireless communication with the printer 10 is performed by the wireless LAN interface 35.

  Then, the CPU 31 acquires information such as a communication result from the wireless LAN interface 35, generates a report indicating information related to wireless communication with the printer 10 in the same manner as described above, and transmits the report as print data to the printer 10 ( S113). Thereafter, the wireless setting process is terminated.

  When wireless communication between the printer 10 and the terminal device 30 is successful, wireless communication can be performed with the USB cable 60 connecting the printer 10 and the terminal device 30 disconnected.

(Effect of Embodiment 1)
As described above, according to the present embodiment, the terminal device 30 that performs the wireless setting of the printer 10 stores the setting item and a plurality of item names indicating the setting item in association with each other, and from among these item names The item name included in the screen for executing the wireless setting of the access point 50 or the terminal device 30 that is the communication destination of the printer 10 is specified.

In this case, image data including a predetermined item name can be generated.

<Embodiment 2>
Next, a second embodiment of the present invention will be described with reference to FIG.
In this embodiment, when the terminal device 30 performs infrastructure mode wireless setting for the printer 10 to communicate with the access point 50, the terminal device 30 acquires information on the access point 50 using the web server function. An example is shown.

  FIG. 9 is a flowchart of the wireless setting process. Note that the configuration of the system of this embodiment is the same as that of FIG.

  In the present embodiment, it is assumed that the terminal device 30 is configured to perform wireless communication with the access point 50 in the infrastructure mode with respect to the wireless LAN interface 35. The terminal device 30 is provided with a wired LAN interface (not shown) instead of the wireless LAN interface 35, and the wired LAN interface is connected to the network line 61 so that the terminal device 30 can communicate with the access point 50. Good.

  When the wireless setting process shown in FIG. 9 is started, the CPU 31 acquires a web page from the access point 50 through the wireless LAN interface 35 (S301). More specifically, an HTTP request for requesting a web page is transmitted from the wireless LAN interface 35 to the IP address of the access point 50.

  Upon receiving this request, the control unit 51 of the access point 50 generates a web page in HTML format or the like from the web page data stored in the EEPROM 53 and transmits it to the terminal device 30 as described above. Here, in the configuration of a general web page, it is considered that a plurality of hyperlinks to other pages are provided on the top page, and pages for wireless setting are included in those pages.

  The CPU 31 of the terminal device 30 determines whether there is a hyperlink to another page in the received web page (S302). If it exists (S302: YES), the request for the other page is sent to the printer 10. And the web page is acquired from the printer 10 (S303). Then, the CPU 31 returns to S302 and repeats the operation of determining whether or not the received web page has a hyperlink to another page that has not been acquired, thereby accumulating data of a plurality of web pages on the RAM 33. .

  When there is no hyperlink to another page that has not been acquired (S302: NO), the CPU 31 searches for a keyword from each acquired web page (S304). Here, for example, the keyword included in the web page is specified using the vendor name and item name registered in the first correspondence table 41 described above as keywords. At this time, keywords may be searched from the entire HTML data (including tags) constituting the web page, or the text of the web page (characters displayed when the web page is read by a web browser) from the HTML tag. ) Only, and the keyword may be searched from there.

  Next, the CPU 31 determines whether a vendor name included in the first correspondence table 41 has been found by searching for a keyword (S305). When a vendor name is found (S305: YES), an item name corresponding to the found vendor name is acquired from the first correspondence table 41 (S306).

  When the CPU 31 does not find the vendor name from the web page (S305: NO), the CPU 31 associates the web page with one setting item among the three setting items included in the first correspondence table 41. It is determined whether an item name has been found (S307). When the item name associated with the setting item is found (S307: YES), the found item name is acquired (S308), and when the associated item name is not found (S307: NO) ), A default item name is acquired from the default value data 42 (S309).

  Then, the CPU 31 determines whether or not there is a next setting item in the first correspondence table 41 (S310). If there is a next setting item (S310: YES), the CPU 31 returns to S307 and handles the next setting item. By repeating the process of determining whether the item name to be found has been found, the item name is acquired for each setting item in the first correspondence table 41.

  When item names are acquired for all setting items in the first correspondence table 41 (S310: NO), or when item names corresponding to vendor names are acquired in S306, the acquired item names are included. Setting screen data is generated, and the setting screen 70 shown in FIG. 5, for example, is displayed on the display unit 37 based on the setting screen data (S311).

  When the user inputs a value from the operation unit 38 to each of the input units 71 to 73 and then clicks the OK button 74, the CPU 31 transmits the input value to the printer 10 as a set value (S312). This wireless setting process is terminated.

  As described above, according to the present embodiment, information that identifies the type (vendor name) of the access point 50 from the web page by accessing the access point 50 from the terminal device 30 or the web page. The included item name is acquired, and thereby the item name used on the setting screen of the access point 50 can be specified.
