Each of the terminals 10 and 40 is a portable terminal device such as a mobile phone (for example, a smartphone), a PDA, or a tablet PC. In the modified example, the terminals 10 and 40 may be stationary terminal devices such as desktop PCs. Since each of the terminals 10 and 40 has the same configuration, the configuration of the terminal 10 will be described below, and the description of the configuration of the terminal 40 will be omitted.

The terminal 10 includes a display unit 12, a Wi-Fi interface 14, a BT (abbreviation of Bluetooth (registered trademark)) interface 16, an operation unit 18, and a control unit 30.

That is, the display unit 12 also functions as an operation unit. In the following, the display unit 12 and the operation unit 18 that function as a touch panel may be collectively referred to as “operation units 12, 18”.

The Wi-Fi I / F14 is a wireless interface for executing wireless communication according to the Wi-Fi standard (hereinafter referred to as "Wi-Fi communication"). The Wi-Fi standard is, for example, the IEEE (abbreviation of The Institute of Electrical and Electronics Engineers, Inc.) 802.11 standard and the equivalent standard (for example, 802.11a, 11b, 11g, 11n, 11ac, etc.). Is.

The BTI / F16 is an I / F for executing wireless communication (hereinafter referred to as "BT communication") in accordance with the BT standard. The BT standard is, for example, the standard of IEEE802.5.1 and a standard equivalent thereto. More specifically, BTI / F16 supports BLE (short for Bluetooth Low Energy). BLE is realized in version 4.0 or later of the BT standard.

Describe the differences between Wi-Fi communication and BT communication. The communication speed of Wi-Fi communication (for example, the maximum communication speed is 600 Mbps) is faster than the communication speed of BT communication (for example, the maximum communication speed is 24 Mbps). The frequency of the carrier wave in Wi-Fi communication is the 2.4 GHz band or the 5.0 GHz band. The frequency of the carrier wave in BT communication is the 2.4 GHz band. That is, when the 5.0 GHz band is adopted as the carrier wave frequency in Wi-Fi communication, the carrier wave frequency in Wi-Fi communication and the carrier wave frequency in BT communication are different. Further, the maximum distance at which Wi-Fi communication can be executed (for example, about 100 m) is larger than the maximum distance at which BT communication can be executed (for example, about several tens of m).

The application 38 may be installed on the terminal 10 from a server on the Internet provided by a vendor such as the printer 100, or may be installed on the terminal 10 from the media shipped together with the printer 100 or the like.

(Configuration of printers 100 to 500)
Each printer 100 to 500 is a peripheral device (for example, a peripheral device of the terminal 10) capable of executing a printing function. The printer 100 has a model name "model1".

It has the same configuration as the printer 100 except that it differs from the IP address of the printer (for example, "i200" of the printer 200).

(Search process for mobile terminals: Fig. 2)
With reference to FIG. 2, the search process executed by the CPU 32 of the mobile terminal 10 according to the application 38 will be described. The search process is started when a search start instruction is received from the user after the application 38 is started. The search start instruction includes the user specifying a search method. The search method is a normal device search or a conditional device search. A normal device search is a method for searching all printers capable of printing. Conditional device search is a method for searching for printers capable of printing according to the printing conditions input by the user.

The processes from S10 to S20 are a series of processes for creating a list. The list is a list of printers that exist around the terminal 10 and can transmit capability information and the like to the terminal 10. In S10, the CPU 32 determines whether or not the advertisement signal has been received from any printer via the BTI / F16. The CPU 32 proceeds to S12 when it is determined that the advertisement signal has been received (YES in S10), and proceeds to S20 when it is determined that the advertisement signal has not been received (NO in S10).

In S12, the CPU 32 determines whether or not the received advertisement signal includes the IP address. Whether or not the advertisement signal includes an IP address depends on the performance of the printer that is the source of the advertisement signal. That is, there are printers (for example, printers 200, 300, 500) capable of transmitting an advertisement signal including an IP address, and printers (for example, printers 100, 400) capable of transmitting an advertisement signal including an IP address. The CPU 32 proceeds to S14 when it is determined that the advertisement signal includes the IP address (YES in S12), and proceeds to S16 when it is determined that the advertisement signal does not include the IP address (NO in S12).

In S16, the CPU 32 determines whether the received advertisement signal is an ADV_IND signal or an ADV_NONCONN_IND signal. In the following, the ADV_IND signal and the ADV_NONCONN_IND signal will be referred to as "AI signal" and "ANI signal", respectively. The AI signal is an advertisement signal including a connection permission parameter indicating that the printer that is the source of the AI signal can establish a BT connection with a terminal (that is, an L2CAP Link connection described later). The ANI signal is an advertisement signal including a connection disapproval parameter indicating that the printer that is the source of the ANI signal cannot establish a BT connection with the terminal. More specifically, each printer 100 to 500 repeatedly transmits an AI signal in a state where a BT connection with another device has not been established, and in a state where a BT connection with another device has been established, the printers 100 to 500 repeatedly transmit the AI signal. The ANI signal is repeatedly transmitted. When the CPU 32 determines that the advertisement signal is an AI signal (YES in S16), the CPU 32 proceeds to S14, and when it determines that the advertisement signal is an ANI signal (NO in S16), the CPU 32 proceeds to S10 without executing S14. Return to.

In S14, the CPU 32 lists information about the printer that is the source of the received advertisement signal. Specifically, the CPU 32 describes the MAC address of the printer included in the advertisement signal and the received radio wave intensity of the advertisement signal in a list in association with each other. When the advertised signal includes an IP address, the CPU 32 also describes the IP address in the list in association with the MAC address and the received radio wave intensity.

In S20, the CPU 32 determines whether or not a predetermined time has elapsed since the process of FIG. 2 was started. The CPU 32 proceeds to S30 when it is determined that the predetermined time has elapsed (YES in S20), and returns to S10 when it is determined that the predetermined time has not elapsed (NO in S20).

The processes of S30 to S100 are a series of processes for displaying one or more printers on which the terminal 10 can execute printing among the printers described in the list. In S30, the CPU 32 sorts the information in the list in order of proximity to the terminal 10. Specifically, the CPU 32 sorts the information in the list in descending order of received radio wave strength. As a result, the CPU 32 can execute the processing after S40 for each printer in the order of the closest distance to the terminal 10.

In S40, the CPU 32 first identifies the highest-level information (that is, information such as the MAC address associated with the highest received radio wave intensity) from the unprocessed information in the sorted list. Then, the CPU 32 determines whether or not the specified information includes the IP address. When the CPU 32 determines that the specified information includes the IP address (YES in S40), the process proceeds to S42, and when it determines that the specified information does not include the IP address (NO in S40), the CPU 32 proceeds to S70. move on.

In S42, the CPU 32 transmits an information request including the IP address specified in S40 as a destination address to the printer via Wi-Fi I / F 14.

In S44, the CPU 32 determines whether or not the information has been received from the printer. The information includes a model name, ability information, and status information. The capability information is information indicating the printing conditions that can be realized by the printer. Specifically, in this embodiment, the capability information includes the paper size and the number of colors (that is, monochrome printing or color printing). In the modification, the capability information may further include information indicating the print resolution, the presence / absence of the double-sided printing function, the presence / absence of the stapler function, and the like. The status information is information indicating the current status of the printer. Specifically, in the present embodiment, the state information includes an idle state waiting for reception of a print instruction, an error state indicating that printing cannot be executed, information indicating the remaining amount of consumables, and the like. .. In the modification, the state information may further include information indicating the communication state of the printer. The CPU 32 proceeds to the process of S50 when it is determined that the information has been received from the printer (YES in S44), and the process of S100 when the predetermined time elapses without receiving the information from the printer (NO in S44). Proceed to.

In S50, the CPU 32 determines whether the search method specified by the user is a conditional device search or a normal device search. The CPU 32 proceeds to S52 when it is determined that the search method is a conditional device search (YES in S50), and proceeds to S60 when it is determined that the search method is a normal device search (NO in S50). ..

In S52, the CPU 32 determines whether or not the ability information received in S44 meets the printing conditions input by the user. When the CPU 32 determines that the capability information conforms to the input print condition (YES in S52), the process proceeds to S60, and when it determines that the capability information does not conform to the input print condition (NO in S52), the CPU 32 proceeds to S60. Proceed to S100.

In S60, the CPU 32 displays a selection screen. When the search method specified by the user is a normal device search (that is, NO in S50), the selection screen includes the model name, capability information, and status information received in S44. When the search method specified by the user is a conditional device search (that is, YES in S50), the selection screen includes the model name and status information received in S44 and does not include the capability information.

In S100, the CPU 32 determines whether or not the processing after S40 has been executed for all the information in the list. When the CPU 32 determines that the process has been executed for all the information (YES in S100), the CPU 32 ends the process of FIG. 2 and determines that the process has not been executed for all the information (NO in S100). , Return to S40.

In S70, the CPU 32 transmits a CONNECT_IND signal including the MAC address in the information specified in S40 as a destination to the printer via the BTI / F16. The signal is a signal requesting the establishment of a BT connection (that is, an L2CAP Link connection). As a result, a BT connection is established between the terminal 10 and the printer.

In S72, the CPU 32 uses the BT connection established in S70 to transmit a Read by Type Request signal (hereinafter, simply referred to as “Read signal”) to the printer via the BTI / F16. The signal is a signal requesting transmission of information. The information includes a model name, capability information, status information, and an IP address.

S80 is the same as S50. If YES in S80, the process proceeds to S82, and if NO in S80, the process proceeds to S90. S82 is the same as S52. If YES in S82, the process proceeds to S90, and if NO in S82, the process proceeds to S100.

In S90, the CPU 32 transmits a confirmation signal including the IP address received in S72 as the destination address to the printer via Wi-Fi I / F14.

In S92, the CPU 32 determines whether or not the response signal has been received from the printer via the Wi-Fi I / F 14. The CPU 32 proceeds to S60 when it is determined that the response signal has been received from the printer (YES in S92), and proceeds to S100 when the predetermined time elapses without receiving the response signal from the printer (NO in S92). ..

(Specific case: Fig. 3 to Fig. 8)
Subsequently, a specific case realized by the process of FIG. 2 will be described with reference to FIGS. 3 to 8. First, a case A in which a normal device search is executed will be described with reference to FIGS. 3 to 6, and then a case B in which a conditional device search is executed will be described with reference to FIGS. 7 and 8. do.

(Case A: FIGS. 3 to 6)
In the initial state of FIG. 3, the terminal 10 and the printers 100 to 400 have established a Wi-Fi connection with the AP50, and the printer 500 has established a Wi-Fi connection with the AP60. Further, the printers 300 and 400 have established a BT connection with the terminal 40 (that is, an L2CAP Link connection described later).

In the following, when the process executed by the CPU 32 of the terminal 10 according to the OS 36 or the application 38 will be described, the OS 36 or the application 38 will be described as the main body. When explaining the process executed by the CPU 132 or the like of the printer 100 or the like according to the program 136 or the like, the printer 100 or the like is not described as the main body, but the printer 100 or the like is described as the main body. Further, in the following, BT communication among BT communication and Wi-Fi communication is mainly executed. Therefore, unless it is clearly stated that it is Wi-Fi communication, each of the following communications is BT communication via BTI / F16 or the like. In each figure after FIG. 3, BT communication and Wi-Fi communication are represented by thin lines and thick lines, respectively.

(Case A: Fig. 3)
Each printer 100 to 500 repeatedly transmits an advertisement signal according to the BT standard while the power is turned on. Each printer 100, 200, 500 has not established a BT connection with a terminal. For this purpose, each printer 100, 200, 500 transmits an AI signal at T10, T12, T18. On the other hand, each of the printers 300 and 400 has established a BT connection with the terminal 40. For this purpose, each printer 300, 400 transmits an ANI signal at T14, T16.

In T20, the operation for activating the application 38 is executed by the user on the operation units 12 and 18, and as a result, the application 38 is activated. In this case, in T22, the application 38 causes the display unit 12 to display the search method selection screen. The search method selection screen includes a button B1 indicating the character string "device search" and a button B2 indicating the character string "conditional device search". Button B1 is a button for starting a normal device search. Button B2 is a button for starting a conditional device search.

In case A, the application 38 accepts an operation of selecting the button B1 from the user in T24 (trigger of the process of FIG. 2). That is, Case A is a case where a normal device search is executed. In case B of FIGS. 7 and 8, button B2 is selected. That is, Case B is a case where a conditional device search is executed.

When the application 38 receives the operation of selecting the button B1 in the T24, the application 38 supplies the search start instruction to the OS 36 in the T26. The search start instruction is a command instructing to search for each printer existing around the terminal 10.

When the OS 36 acquires a search start instruction from the application 38 in the T26, the OS 36 receives an AI signal or an ANI signal from the printers 100 to 500 in the T30 to T38. The advertisement signal of T30 received from the printer 100 includes the MAC address “m100” of the BTI / F116 of the printer 100. Similarly, each advertisement signal of T32 to T38 received from each printer 200 to 500 has the MAC address of the source printer (that is, "m200", "m300", "m400", or "m500"). include. Each of the T32, T34, T38 advertisement signals received from the printers 200, 300, 500 further includes the IP address of the source printer (ie, "i200", "i300", or "i500").

The OS 36 supplies the received information to the application 38 in the T40. Note that FIG. 3 shows that after the advertisement signals are received from all the printers 100 to 500, the received information is supplied from the OS 36 to the application 38. However, in reality, the OS 36 supplies the reception information to the application 38 each time the advertisement signal is received from one printer. That is, each time the application 38 receives an advertisement signal from one printer, the application 38 acquires the reception information from the OS 36 (YES in S10 of FIG. 2). The received information includes the type of the advertisement signal received from the printer that is the source of the advertisement signal (that is, the AI signal or the ANI signal), the MAC address included in the advertisement signal, and the received radio wave strength of the advertisement signal. .. If the advertised signal includes an IP address, the received information also includes the IP address.

When the application 38 acquires each reception information corresponding to each printer 100 to 500 from the OS 36 in the T40, the application 38 creates a list in the T42 (S12 to S16). The list is a list of printers capable of transmitting capability information and the like to the terminal 10. Specifically, the application 38 has the printers 200, 300, 500 (YES in S12) of the advertisement signal source including the IP address and the printer 100 (YES in S12) of the AI signal transmission source based on each received information. YES) and specify. Then, the application 38 describes the MAC addresses of the specified printers 100, 200, 300, and 500 in the order of receiving the advertisement signals in a list in association with each other. Further, the application 38 also describes the IP address in the list in association with the MAC address and the received radio wave strength for each of the printers 200, 300, and 500. As described above, since the terminal 10 does not describe the MAC address of the printer 400 from which the capability information and the like cannot be acquired in the list, a process for executing communication with the printer 400 (for example, T50 in FIG. 4 described later). It is not necessary to execute the process of T52 or the like).

Next, the application 38 sorts the list generated by the T42 in the order of the closest distance to the terminal 10 by using the received radio field strength corresponding to each printer 100, 200, 300, 500 in the T44 (S30). .. Specifically, the application 38 describes the MAC address "m200" and the IP address "i200" of the printer 200 corresponding to the maximum received radio wave intensity "-50 dBm" at the first position (that is, the highest level) in the list. Next, the application 38 describes the MAC address "m500" and the IP address "i500" of the printer 500 corresponding to the second highest received radio field intensity "-60 dBm" second in the list. Similarly, the application 38 describes the MAC address "m100" of the printer 100 in the third place in the list, and describes the MAC address "m300" and the IP address "i300" of the printer 300 in the fourth place (that is, the lowest position) in the list. do.

(Continued from Fig. 3: Fig. 4)
Next, the terminal 10 executes communication with each printer 100, 200, 300, 500 according to the order of the sorted list. That is, the terminal 10 first executes communication with the printer 200, and then sequentially executes communication with each of the printers 500, 100, and 300. Therefore, the terminal 10 can receive information from the printers 100, 200, etc. in the order of the closest distance to the terminal 10, and as a result, the information about the printers having the closest distance to the terminal 10 is preferentially displayed. be able to.

At T50, the application 38 identifies the highest MAC address "m200" and the IP address "i200" in the sorted list, and supplies an acquisition instruction including the IP address "i200" to the OS 36 (S42). The acquisition instruction is a command instructing the transmission of an information request including an IP address as a destination address.

When the OS 36 acquires an acquisition instruction from the application 38 in the T50, the OS 36 transmits an information request including the IP address "i200" included in the acquisition instruction as the destination address in the T52 via the Wi-Fi I / F14. That is, the OS 36 transmits the information request to the printer 200. In this way, the terminal 10 can transmit the information request to the printer 200 without receiving an additional operation from the user after receiving the operation of the T24 from the user via the operation units 12 and 18. As a result, the terminal 10 can acquire the capability information and the like from the printer 200, and can display the capability information and the like. Therefore, the user can easily know the information of the printer 200 without performing a large number of operations.

The OS 36 receives various information (that is, model name “model 2”, capability information, state information) from the printer 200 via the Wi-Fi I / F 14 at the T54. In this case, the OS 36 supplies the application 38 with the acquisition notification including the received information in the T56.

When the application 38 receives the acquisition notification from the OS 36 (YES in S44), the application 38 displays the printer selection screen on the display unit 12 in T60 (S60). The printer selection screen includes information B3 regarding the printer 200. Specifically, the information B3 includes the model name "model2" received by the T54, the capability information, and the state information. As a result, the user can know the information B3 regarding the printer 200. Then, if the user selects the information B3, the terminal 10 can make the printer 200 execute printing by using Wi-Fi communication. If, for example, a problem occurs in the AP50, Wi-Fi communication cannot be executed between the terminal 10 and the printer 200. In this case, the application 38 cannot receive the acquisition notification from the OS 36 (NO in S44) and does not display the information B3 regarding the printer 200. This is because the terminal 10 cannot cause the printer 200 to perform printing using Wi-Fi communication.

Next, the terminal 10 identifies the next highest MAC address "m500" and the IP address "i500" in the sorted list, and executes the same processing as the T50 to T56 at the T70 to T76 with the printer 500. .. In this case, since the AP50 and AP60 belong to the same LAN, communication between the terminal 10 and the printer 500 is performed via the AP50 and AP60 (see T72 and T74).

When the application 38 acquires the acquisition notification from the OS 36 in the T76, the application 38 adds the information B4 regarding the printer 500 to the printer selection screen in the T80 (S60). That is, the application 38 causes the display unit 12 to display the information B4 regarding the printer 500 in addition to the information B3 regarding the printer 200. Therefore, the user can simultaneously view a plurality of information B3 and B4 relating to the plurality of printers 200 and 500. In particular, the application 38 does not display the printer selection screen after the information is acquired from each of the plurality of printers 200 and 500, but the printer containing only the information B3 at the stage when the information is acquired from the printer 200. Display the selection screen. After that, when the information is acquired from the printer 500, the application 38 adds the information B5 to the printer selection screen. For this purpose, the application 38 can quickly provide the information B3 to the user. Therefore, the user can quickly select the information B3. Further, the application 38 displays the information B4 below the previously displayed information B3. That is, the application 38 preferentially displays the information B3 regarding the printer 200, which is close to the terminal 10. As a result, the user can preferentially select the information B3 regarding the printer 200 which is close to the terminal 10.

(Continued from Fig. 4: Fig. 5)
Next, as shown in FIG. 5, in T90, the application 38 identifies the next highest MAC address “m100” in the sorted list, and sends a connection instruction including the MAC address “m100” to the OS36. Supply (NO in S40, S70). The connection instruction is a command for instructing the establishment of a BT connection and the communication of information using the BT connection. In this way, when the terminal 10 receives the advertisement signal not including the IP address from the printer 100, the terminal 10 establishes a BT connection with the printer 100 by using the MAC address of the BTI / F of the printer 100, and BT communication. Is used to receive various information from the printer 100. The terminal 10 can acquire various information from each printer 100 by using an appropriate method depending on whether or not the advertisement signal includes an IP address.

When the OS36 acquires the connection instruction from the application 38 in the T90, the OS36 transmits the CONNECT_IND signal including the MAC address "m100" included in the connection instruction as the destination address in the T92. That is, the OS 36 transmits the signal to the printer 100. As a result, in T94, a BT connection is established between the terminal 10 and the printer 100.

When the BT connection is established at T94, the printer 200 stops transmitting the AI signal at T100 and starts transmitting the ANI signal at T102. As described above, the ANI signal is a signal indicating that a BT connection cannot be established. Therefore, it is possible to prevent the printer 100 from starting the process for establishing the BT connection with another terminal while the printer 100 has established the BT connection with the terminal 10. As a result, it is possible to suppress the occurrence of an event in which the BT connection between the printer 100 and the terminal 10 is disconnected due to the start of the process.

The OS 36 uses the BT connection established in the T94 to transmit a Read signal to the printer 100 at the T110.

When the printer 100 receives a Read signal from the terminal 10 in the T110, the printer 100 transfers various information of the printer 100 (that is, model name "model1", IP address "i100", capability information, and status information) to the terminal 10 in the T112. Send. In FIG. 5, various information is expressed so as to be transmitted to the terminal 10 in response to one Read signal, but in reality, a plurality of Read signals corresponding to the various information are sequentially transmitted to the printer 100. It is transmitted, and various information is sequentially transmitted to the terminal 10.

When the OS 36 receives various information from the printer 100 in the T112, the OS 36 supplies the various information to the application 38. When the application 38 acquires various information from the OS 36, the application 38 supplies a disconnection instruction to the OS 36 at the T120. The disconnection instruction is a command instructing to disconnect the BT connection. When the OS 36 acquires a disconnection instruction from the application 38 in T120, the OS36 transmits a disconnection signal to the printer 100 in T122.

When the printer 100 receives the disconnection signal from the terminal 10 at T122, the printer 100 disconnects the BT connection with the terminal 10 at T124. Then, the printer 100 transmits an AI signal instead of the ANI signal at T126.

After that, the application 38 supplies the OS 36 with a confirmation instruction including the IP address “i100” of the printer 100 received by the T112 in the T130. The confirmation instruction is a command for instructing confirmation of whether or not Wi-Fi communication can be executed between the terminal 10 and the printer 200 (that is, whether or not the terminal 10 can execute printing). Is.

When the OS36 acquires the confirmation instruction from the application 38 in the T130, the OS36 inputs the confirmation signal including the IP address "i100" of the printer 100 in the confirmation instruction as the destination address to the AP50 via the Wi-Fi I / F14 in the T132. Send.

When the printer 200 receives the confirmation signal from the terminal 10 at T132, the printer 200 transmits the response signal to the terminal 10 via the AP50 at T134. As described above, since the printer 100 transmits the IP address to the terminal 10 (see T112), the confirmation signal can be appropriately received from the terminal 10, and as a result, the response signal can be appropriately transmitted to the terminal 10. Can be done.

When the OS 36 receives the response signal from the printer 100 in the T134, the OS 36 supplies the continuity notification to the application 38 in the T136. The continuity notification is a notification indicating that Wi-Fi communication can be executed between the terminal 10 and the printer 100.

When the application 38 acquires the continuity notification from the OS 36 in T136, the application 38 adds the information B5 about the printer 100 to the printer selection screen in T140 (S60). That is, the application 38 causes the display unit 12 to display the information B5 regarding the printer 100 in addition to the information B3 regarding the printer 200 and the information B4 regarding the printer 500. For this purpose, the user can simultaneously view a plurality of information B3, B4, B5 regarding the plurality of printers 200, 500, 100. If, for example, a problem occurs in the AP50, Wi-Fi communication cannot be executed between the terminal 10 and the printer 100. In this case, the application 38 cannot receive the continuity notification from the OS 36 (NO in S92) and does not display the information B5 regarding the printer 100. This is because the terminal 10 cannot cause the printer 100 to perform printing using Wi-Fi communication.

(Continued from Fig. 5: Fig. 6)
Next, as shown in FIG. 6, the terminal 10 identifies the next highest MAC address “m300” and the IP address “i300” in the sorted list, and performs the same processing as T50 to T56 in FIG. Is executed with the printer 300. Then, the application 38 adds the information B6 about the printer 300 to the printer selection screen in the T150 (S60). The printer 300 has established a BT connection with the terminal 40 (see the initial state in FIG. 3), and transmits an ANI signal (T34). In this way, even when the printer 300 has established a BT connection with another device (that is, the terminal 40), the application 38 uses the IP address included in the ANI signal to perform Wi-Fi communication. By executing the printer 300, various information can be appropriately acquired from the printer 300.

The application 38 accepts the selection of the information B3 regarding the printer 200 from the user in the T160. In this case, the application 38 registers the printer 200 as the default printer in the memory 34 in T162. Specifically, the application 38 uses the model name "model2" of the printer 200, the capability information of the printer 200 (that is, the printing papers "A4, A3", the number of colors "color, monochrome"), and the IP address of the printer 200 ". i200 ”is registered in the memory 34. As a result, the application 38 can cause the printer 200, which is the default printer, to perform printing when receiving a print operation from the user.

The application 38 accepts a print operation from the user at T164. The print operation includes an operation of selecting image data representing an image to be printed and an operation of accepting input of print settings (paper size, number of colors, etc.). Here, as the print setting, a print setting that matches the capability information of the registered printer 200 is selected. Then, the application 38 converts the image data according to the input print settings to generate print data having a data format that can be interpreted by the printer 200. Next, in T166, the application 38 supplies a print instruction including the generated print data and the IP address “i200” of the registered printer 200 to the OS 36.

When the OS 36 acquires a print instruction from the application 38 in T166, the OS 36 transmits print data in T168 via the Wi-Fi I / F14 with the IP address "i200" in the print instruction as the destination address. That is, the OS 36 executes Wi-Fi communication and transmits print data to the printer 200.

When the printer 200 receives the print data from the terminal 10 at T168, the printer 200 executes printing of the image represented by the print data at T170.

(Processing of Case B: FIGS. 7, 8)
Subsequently, the process of the case B in which the conditional device search is executed will be described with reference to FIGS. 7 and 8. The initial state of FIG. 7 is the same as the initial state of case A of FIG.

(Processing in FIG. 7)
The same process as T10 to T22 in FIG. 3 is executed. After that, in T180, the application 38 accepts the selection of the button B2 in the search method selection screen from the user. In this case, the application 38 causes the display unit 12 to display the condition input screen in T182. The condition input screen includes a button for accepting input of print conditions and a button B7 indicating a character string "search". The application 38 accepts input of desired printing conditions (“A3” and “color printing” in this case) from the user, and accepts an operation of selecting the button B7 in T184. After that, the same processing as that of T26 to T44 in FIG. 3 is executed.

(Continued from Fig. 7: Fig. 8)
Then, as shown in FIG. 8, the same processing as in T50 to T56 in FIG. 4 is executed with the printer 200. The application 38 determines in T190 that the printing conditions (that is, A3 and color printing) input in T184 of FIG. 7 are included in the capability information of the printer 200 (that is, A3, A4, color printing, monochrome printing). (YES in S50 and YES in SS52 in FIG. 2). That is, the application 38 determines that the input printing conditions match the capability information of the printer 200.

Next, in T192, the application 38 causes the display unit 12 to display the printer selection screen (S60). The printer selection screen includes the model name "model 2" of the printer 200 and the information B8 indicating the status information. The information B8 does not include the capability information of the printer 200, unlike the information B3 on the printer selection screen of FIG. This is because the printing conditions have been input by the user (see T182 and T184 in FIG. 7), and it has been confirmed that the printing conditions match the capability information of the printer 200 (T190).

After that, the same processing as that of T70 to T76 in FIG. 4 is executed with the printer 500. The application 38 determines in T200 that the printing conditions (that is, A3 and color printing) entered in T184 of FIG. 7 are not included in the capability information of the printer 500 (that is, A4, A3, B5, monochrome printing). (YES in S50 and NO in S52 in FIG. 2). That is, the application 38 determines that the input printing conditions do not match the capability information of the printer 500. In this case, the application 38 does not display the information about the printer 500 on the printer selection screen. This is because the printer 500 cannot perform printing according to the printing conditions desired by the user.

After that, the same processing as that of T90 to T126 of FIG. 5 is executed with the printer 100. The application 38 determines in T210 that the print conditions (that is, A3 and color printing) entered in T184 of FIG. 7 are not included in the capability information of the printer 100 (that is, A4, B5, color printing) (FIG. YES for S80 and NO for S82). In this case, the information about the printer 100 is not displayed on the printer selection screen.

After that, the same processing as that of T50 to T56 of FIG. 4 is executed with the printer 300. The application 38 determines in T220 that the printing conditions (that is, A3 and color printing) entered in T184 of FIG. 7 are included in the capability information of the printer 300 (that is, A3, color printing, monochrome printing) (FIG. YES for S50 of 2 and NO for S52). In this case, the application 38 adds the information B9 about the printer 300 to the printer selection screen in T222.

When the application 38 receives the selection of the information B8 from the user in T232, the application 38 executes the same process as T162 to T170 in FIG.

(Effect of this example)
According to this embodiment, when the terminal 10 receives the advertisement signal including the IP address "i200" from the printer 200 via the BTI / F16 (T32 in FIG. 3), the terminal 10 receives the advertisement signal via the Wi-Fi I / F14. An information request including the IP address "i200" as a destination address is transmitted to the printer 200 (T52). Therefore, the terminal 10 can receive various information from the printer 200 via the Wi-Fi I / F 14 (T54). In this way, the terminal 10 can appropriately acquire information about the printer 200 when the IP address "i200" is included in the advertisement signal received from the printer 200.

In particular, in this embodiment, the terminal 10 does not search for each printer 100 to 500 using Wi-Fi communication, but searches for each printer 100 to 500 using BT communication. The reason is as follows. When the terminal 10 adopts a configuration in which a printer is searched by using Wi-Fi communication, the terminal 10 transmits a broadcast search signal to the AP50. In this case, since the subnet of AP50 and the subnet of AP60 are different, there is a high possibility that the search signal does not reach the printer 500 connected to AP60. That is, the terminal 10 can find the printers 100 to 400, but it is highly possible that the printer 500 cannot be found. On the other hand, according to the present embodiment, since the terminal 10 searches for printers by using BT communication, all the printers 100 to 500 existing around the terminal 10 can be appropriately found. For this purpose, the terminal 10 can display a printer selection screen including information B4 regarding the printer 500 (see T80 in FIG. 4).

The techniques described in the claims include various modifications and modifications of the specific examples exemplified above. Modifications of the above embodiment are listed below.

(Modification 1) In T72 of FIG. 3, the terminal 10 may receive only one of the capability information and the state information from the printer 200. Generally speaking, the "first related information" may include at least one of the "first ability information" and the "first state information". The same applies to the "second related information" and the "third related information".

(Modification 2) The terminal 10 does not have to display information about other printers 100, 300, 500 after displaying information about the printer 200 in T60 of FIG. That is, the terminal 10 does not have to execute T70 in FIG. 4 to T150 in FIG. In this modification, the "second information request transmitting unit", "second related information receiving unit", "establishment unit", and "third related information receiving unit" can be omitted.

(Modification 3) Each signal of T30 to T38 in FIG. 3 may include a transmission radio wave intensity. In this case, the terminal 10 may calculate the distance between the printer and the terminal 10 in the T44 by using the transmitted radio wave strength and the received radio wave strength for each of the printers 100, 200, 300, and 500. Then, the terminal 10 sorts the printers 100, 200, 300, and 500 in ascending order of distance. Generally speaking, the "distance determination unit" determines which of the first distance and the second distance is smaller by using only the received radio field intensity as in the above embodiment. Alternatively, as in the present modification, both the received radio wave strength and the transmitted radio wave strength may be used to determine which of the first distance and the second distance is smaller.

(Modification 4) The process of T44 in FIG. 3 may not be executed. In this modification, the "distance determination unit" can be omitted.

(Modification 5) The terminal 10 displays a printer selection screen including information B3 to B6 regarding each printer 100, 200, 300, 500 after receiving capability information and the like from each printer 100, 200, 300, 500. May be good. Generally speaking, the "display control unit" does not have to display the second display information on the display unit in addition to the first display information after the first display information is displayed on the display unit. ..

(Modification 6) The process of T50 in FIG. 4 may be executed in response to the reception of a predetermined operation from the user via the operation units 12 and 18. Generally speaking, the "first information request transmitting unit" may transmit the first information request to the first communication device in response to receiving an instruction from the user via the operation unit.

(Modification 7) In T40 of FIG. 2, the terminal 10 may generate a list including the MAC address “m400” of the printer 400 that is the source of the ANI signal that does not include the IP address. That is, a list containing the MAC addresses of all printers 100-500 may be generated. In this case, the terminal 10 also establishes a BT connection with the printer 400 after the printer 400 disconnects the BT connection with the terminal 40, and receives various information from the printer 400. Generally speaking, a third wireless connection with a third communication device may be established when an advertisement signal containing impossible information is received from the third communication device. In another variant, the advertised signal may be free of connection permit and disallow parameters. Also in this variant, a list containing the MAC addresses of all printers 100-500 is generated.

(Modification 8) In T130 and T132 of FIG. 5, the terminal 10 may transmit a multicast confirmation signal including an IP address in a predetermined range as a destination address. In this case, the terminal 10 can determine that Wi-Fi communication with the printer 100 can be executed when receiving the response signal including the IP address received by the T112 as the source address. Generally speaking, the "first determination unit" may make a determination using the third IP address.

(Modification 9) T130 to T136 in FIG. 5 may be omitted. In this case, the terminal 10 displays information about the printer on the printer selection screen regardless of whether or not Wi-Fi communication with the printer can be executed. In this modification, the "first determination unit" can be omitted.

(Modification 10) In T182 of FIG. 7, the terminal 10 may display a screen for designating a printer state instead of a screen for designating print conditions. In this case, the terminal 10 displays information about the printers 200 and 500 when receiving input in an idle state, for example, from the user, and displays information about the printer 100 when receiving input in a state where the toner is low, for example, from the user. .. In this modification, the information indicating the printer status is an example of "target information".

(Modification 11) T22 and T24 in FIG. 3 may be omitted. In this case, the terminal 10 executes a normal device search. In this modification, the "second reception unit" can be omitted.

(Modification 12) T160 and T162 in FIG. 6 may be omitted. That is, the terminal 10 may be any as long as it provides the user with information about the printer existing around the terminal 10, and may not cause the printer to perform printing. In this modification, the "registration unit" can be omitted.

(Modification 13) The “communication device” may not be a printer, but may be another image processing device such as a scanner or a facsimile. In this case, the capability information may include, for example, information indicating the scan resolution, the number of scan colors, the presence / absence of the double-sided scan function, and the like. Further, the status information may include information indicating an error status, a facsimile communication status, and the like. In another modification, the "communication device" may be an information processing device such as a PC or a server. In this case, the capability information may include, for example, information indicating the processing speed, communication speed, type of installed application, and the like. Further, the state information may include information indicating an error state, a data communication state, a data processing state, and the like.

(Modification 14) In the above embodiment, each process of FIGS. 2 to 8 is realized by executing the program 36 by the CPU 32 of the terminal 10. Instead of this, any of the processes may be realized by hardware such as a logic circuit.
