  However, conventionally, if a printer is purchased and the registration operation described above is performed, there is a problem that the user cannot easily determine whether or not the printer can execute printing by sending an e-mail from an arbitrary communication terminal. For example, in an environment where the printer is connected to the Internet via a proxy server, the proxy server may block communication between the print control server and the printer. Even if the printer is installed in an environment where communication between the print control server and the printer is blocked by a proxy server or the like, the print control server cannot be used. However, it is difficult to determine whether or not the communication between the print control server and the printer is interrupted without expertise.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In addition, the same code | symbol is attached | subjected to the corresponding component in each figure, and the overlapping description is abbreviate | omitted.
1. Configuration FIG. 1 is a block diagram showing an overall configuration of a print trial system including a print control server 1 as an embodiment of the present invention.

  The print control server 1 receives the e-mail transmitted to the e-mail address associated with the printer 3 registered in the print control server 1 to cause the printer 3 to print the e-mail text or attached file. It is a computer that provides Specifically, the print control server 1 is a computer including a CPU, a RAM, a ROM, an HDD (hard disk device), an interface circuit, and the like, and a CPU loads a print control program stored in the HDD into the RAM. By executing this, it functions as a registration unit 11, a print request receiving unit 12, a job notification unit 13, and a print data management unit 14. The registration unit 11 has a function of assigning and registering a communication identifier to each printer in response to a request from an arbitrary printer. The print request receiving unit 12 has a function as an SMTP server that receives an e-mail as a print request using an identifier assigned to each printer. In response to the email as the print request, the job notification unit 13 communicates with the corresponding printer bidirectionally based on XMPP as the bidirectional communication protocol using the identifier of the corresponding printer. It has a function as an XMPP server that notifies a corresponding printer of a print job. The print data management unit 14 functions as a data conversion server that converts the body or attached file of an e-mail into print data in response to an e-mail as a print request, and outputs the generated print data in response to a print data request. It has a function as an HTTP server that transmits to a corresponding printer.

The printer 3 registered in the print control server 1 communicates with the print control server 1 via the Internet, thereby acquiring print data from the print control server 1 in response to the occurrence of a print job and executing printing. Have
Here, a process of registering the printer 3 in the print control server 1 and causing the printer 3 to print using e-mail will be described. First, the computer 6 as the first communication terminal transmits a setup start request to the printer 3 by communicating with the printer 3 using HTTP.

  The printer 3 that has acquired the setup start request transmits, as a registration request corresponding to the printer 3, the model ID of the printer 3, the serial number of the printer 3, and the like to the URL of the print control server 1 corresponding to the registration request using HTTP. To do. The print control server 1 that has acquired the registration request registers the printer 3 in the print control server 1 based on the registration request. Specifically, the registration unit 11 sets the identifier such as the internal ID corresponding to the model ID and serial number of the printer 3, the XMPP login password, and the e-mail address to the printer 3 so as not to overlap with other registered printers. Assign and remember. By assigning an internal ID based on the model ID and serial number of the printer 3, even if the serial number is assigned to the printer in a different system for each model, the internal ID that is different for each printer body is surely printed 3 can be assigned. The registration unit 11 registers the e-mail address assigned to the printer 3 in the print request reception unit 12. By registering the e-mail address assigned to the printer 3 in the print request receiving unit 12, the print control server 1 can receive an e-mail as a print request using the printer 3 as an output device. The registration unit 11 registers the internal ID assigned to the printer 3 and the XMPP login password in the job notification unit 13 in association with each other. The XMPP JID for the job notification unit 13 to communicate with the printer 3 using XMPP is “internal ID” @ ”XMPP domain name of the job notification unit 13”. By registering the internal ID of the printer 3 and the XMPP login password in the job notification unit 13 as XMPP connection information, the printer 3 and the print control server 1 can communicate using XMPP. The registration unit 11 that has registered the printer 3 in the print control server 1 transmits the registration result information of the printer 3 to the printer 3 that is the transmission source of the registration request. The registration result information includes an internal ID assigned to the printer 3, an XMPP login password, an e-mail address, and a domain name of the job notification unit 13. The printer 3 that has acquired the registration result information stores the internal ID assigned to the printer 3, the XMPP login password, the e-mail address, and the domain name of the job notification unit 13 in the nonvolatile memory. Subsequently, the printer 3 generates an XMPP JID from the internal ID and the XMPP domain name, and transmits the XMPP JID and the XMPP login password to the job notification unit 13 of the print control server 1 as XMPP connection information. The job notification unit 13 that has acquired the XMPP JID and the XMPP login password from the printer 3 establishes an XMPP connection with the printer 3 and transmits an XMPP connection result (success / failure) to the printer 3. If the XMPP connection is successful at this time, the XMPP connection between the printer 3 and the job notification unit 13 is continued until the printer 3 is powered off or a communication trouble occurs.

  When the printer 3 is registered in the print control server 1 in this way, any user can cause the printer 3 to execute printing using an e-mail addressed to the e-mail address assigned to the printer 3. . Specifically, it is as follows.

A user who wants to cause the printer 3 to execute printing generates an e-mail including a text or an attached file as a print target using the second communication terminal, and the generated e-mail is an e-mail assigned to the printer 3 Send to address as print request.
When an e-mail as a print request is transmitted, the print control server 1 receives this and generates a print job corresponding to the print request. Specifically, when the print request receiving unit 12 receives an e-mail addressed to a registered e-mail address, the print data management unit 14 acquires and analyzes the e-mail, and attaches a text and a predetermined format. A file is extracted as a print target, and a job ID is assigned to each file for the extracted print target. Then, the print data management unit 14 specifies the internal ID and model ID of the printer 3 corresponding to the e-mail address that is the destination of the e-mail, and corresponds each print target to the model of the printer 3 based on the model ID. The print data is stored as a print job of the printer 3 by converting into print data and associating it with the internal ID and job ID of the printer 3. Subsequently, the print data management unit 14 notifies the job notification unit 13 of the occurrence of the print job together with the internal ID of the printer 3. The job notification unit 13 notified of the generation of the print job notifies the printer 3 of the generation of the print job by transmitting the print job information using XMPP. As described above, since XMPP is used for processing from receiving a print request to notifying the printer 3 of the occurrence of a print job, the print control server 1 can autonomously execute the polling from the printer 3. do not need. Therefore, the occurrence of a print job can be immediately notified to the printer 3, and the occurrence of a print job can be notified to the printer 3 with a minimum communication amount.

  The printer 3 notified of the occurrence of the print job requests print data from the print data management unit 14 by transmitting print job information including the job ID to the print control server 1 using HTTP. The print data management unit 14 that has requested the print data transmits the print data to the printer 3 using HTTP. The printer 3 that has acquired the print data executes printing based on the print data.

  Thus, in the process in which the printer 3 registered in the print control server 1 executes printing in response to a print request, communication based on SMTP, HTTP, and XMPP is executed. The printing trial system of the present embodiment purchases a new printer and registers it in the print control server 1, and a person who wants to execute printing in response to a print request before purchasing the printer Make it easy to see if it is feasible.

2. Printing Trial Method The printing trial system of the present embodiment communicates with the virtual printer 53 as to whether or not the printer can communicate with the print control server 1 based on HTTP and XMPP when the printer is installed under specific conditions. Try by. For this reason, the print trial system of this embodiment includes the print control server 1 and the wireless terminal 5 that is virtualized as the virtual printer 53.

  The registration unit 11 of the print control server 1 has a function of registering the identifier of the wireless terminal 5 as a temporary identifier and transmitting a virtualization program for virtualizing the wireless terminal 5 as a virtual printer to the wireless terminal 5. .

  The wireless terminal 5 is a tablet PC (Personal Computer) managed by a person who newly purchases a printer and tries to register it in the print control server 1. In this embodiment, a tablet PC is used as the print trial device. However, any device such as a desktop computer or a mobile phone terminal can be used as the print trial device as long as the device includes a computer that can be connected to the Internet. Also good. In this embodiment, it is assumed that a MUA (Mail User Agent) 51 and a browser 52 are installed in the wireless terminal 5 before accessing the print control server 1 to use the wireless terminal 5 as a print trial device. explain. That is, the wireless terminal 5 needs an e-mail transmission function and a web page browsing function.

  A function as a first communication terminal used when registering the printer 3 in the print control server 1 and a function as a second communication terminal used when transmitting a print request corresponding to the printer 3 are provided. The wireless terminal 5 is responsible, and the wireless terminal 5 is virtualized so that the wireless terminal 5 itself also functions as a printer. Hereinafter, it demonstrates in detail based on FIG.

  First, a person who purchases a new printer and wants to register it in the print control server 1 (hereinafter referred to as a user) connects the wireless terminal 5 to the LAN to which the printer is to be connected, and uses the browser 52 of the wireless terminal 5. To send a trial request (S101). Specifically, the browser 52 transmits an HTTP request to the URL of the registration unit 11 corresponding to the trial request, thereby acquiring a web page for inputting trial request information. Subsequently, the user inputs, as trial request information, the model of the printer scheduled to be purchased via the web page acquired by the wireless terminal 5. The input trial request information is transmitted to the registration unit 11 by the browser 52 based on HTTP.

  The print control server 1 that has received the trial request transmits to the wireless terminal 5 a virtualization program for operating the wireless terminal 5 as a virtual printer (S201). Specifically, the registration unit 11 may start transmission of the virtualization program based on HTTP in response to reception of the trial request, or a web for downloading the virtualization program in response to reception of the trial request. The virtualization program may be transmitted to the wireless terminal 5 after the page is transmitted to the wireless terminal 5 and a download request is acquired from the wireless terminal 5 based on HTTP. The virtualization program sent here is a program that corresponds to the model that is included in the trial request information as a printer that the user plans to purchase, so that the specifications of the printer that the user plans to purchase are faithful. The wireless terminal 5 can be operated as an operating virtual printer.

  The wireless terminal 5 that has received the virtualization program installs the virtualization program (S103). In the process in which the virtualization program is installed in the wireless terminal 5, program data constituting the virtualization program is stored in the nonvolatile memory of the wireless terminal 5, and the wireless terminal 5 communicates with the print control server 1 as a virtual printer. An identifier (hereinafter referred to as a virtual printer identifier) or the like is set. That is, the identifier of the virtual printer is stored in the RAM or non-volatile memory of the wireless terminal 5. As an identifier for the wireless terminal 5 to communicate with the print control server 1 as a virtual printer, an identifier unique to the wireless terminal 5 such as a MAC address may be used. The written identifier may be used, or a character string arbitrarily determined by the user may be used. However, the identifier of the virtual printer must be unique for each trial terminal so that the print control server 1 can individually communicate with each of a plurality of computers functioning as trial terminals.

  When the virtualization program is executed in the wireless terminal 5, the wireless terminal 5 is virtualized as a virtual printer 53 that behaves in the same way as a printer with respect to the print control server 1. The virtual printer 53 communicates bidirectionally based on the HTTP communication unit 531 having a function of communicating with the print data management unit 14 of the print control server 1 based on HTTP, and the job notification unit 13 of the print control server 1 based on XMPP. An XMPP communication unit 532 having a function and a trial result notification unit 533 having a function of notifying a user of a result of communication with the print control server 1 as a virtual printer are provided.

  When the virtual printer identifier is set in the wireless terminal 5 in the process of installing the virtualization program in the wireless terminal 5, the wireless terminal 5 transmits a temporary registration request based on HTTP to the registration unit 11. The temporary registration request corresponds to a registration request transmitted from the printer 3 to the print control server 1 when registering the actual printer 3 in the print control server 1. Specifically, the HTTP communication unit 531 of the virtual printer 53 transmits the model ID corresponding to the virtual printer 53, the identifier of the virtual printer 53, and the like to the URL of the print control server 1 corresponding to the registration request using HTTP. . The model ID corresponding to the virtual printer 53 is the model ID of the printer that the user plans to purchase.

  The print control server 1 that has acquired the temporary registration request registers the virtual printer 53 in the print request receiving unit 12 based on the temporary registration request (S203). Specifically, as in the case of registering the actual printer 3, the registration unit 11 stores an identifier such as an internal ID corresponding to the model ID corresponding to the virtual printer 53 and an identifier, an XMPP login password, and an e-mail address. The virtual printer 53 is allocated and stored so as not to overlap with other registered printers and other virtual printers. Then, the print request receiving unit 12 registers the email address assigned to the virtual printer 53 (S301). By registering the e-mail address assigned to the virtual printer 53 in the print request receiving unit 12, the print control server 1 can receive an e-mail as a print request corresponding to the virtual printer 53. Also, the job notification unit 13 registers the internal ID assigned to the virtual printer 53 and the XMPP login password in association with each other (S501). By registering the internal ID and login password assigned to the virtual printer 53 in the job notification unit 13, the virtual printer 53 and the print control server 1 can communicate bidirectionally based on XMPP.

  When the virtual printer 53 is registered, the print control server 1 transmits the registration result to the virtual printer 53 (S205). Specifically, the registration unit 11 transmits registration result information to the virtual printer 53 that is the transmission source of the temporary registration request based on HTTP, similarly to the case of transmitting the registration result to the actual printer 3. The registration result information includes an internal ID as an identifier assigned to the virtual printer 53, an XMPP login password and an e-mail address, and a domain name of the job notification unit 13. The HTTP communication unit 531 of the virtual printer 53 that has acquired the registration result information stores the internal ID assigned to the virtual printer 53, the XMPP login password, the e-mail address, and the domain name of the job notification unit 13.

  Subsequently, the XMPP communication unit 532 of the virtual printer 53 generates an XMPP JID from the internal ID and the XMPP domain name as identifiers, transmits the XMPP JID and the XMPP login password to the job notification unit 13 as XMPP connection information, and establishes the XMPP connection. Establish (S105). The job notification unit 13 that has acquired the XMPP JID and the XMPP login password from the printer 3 transmits the XMPP connection result (success / failure) to the XMPP communication unit 532.

  As shown in FIG. 1, when the wireless terminal 5 is connected to a LAN connected to the Internet via the proxy server 4, bidirectional communication based on XMPP between the virtual printer 53 and the print control server 1 is performed. May be blocked. In such a case, a response to the message transmitted from the virtual printer 53 to the print control server 1 does not return from the print control server 1 to the virtual printer 53. When the XMPP connection is successful, the XMPP connection between the virtual printer 53 and the job notification unit 13 is continued until the execution of the virtual printer 53 is completed.

  In the process so far, communication similar to that performed when registering the actual printer 3 in the print control server 1 is performed between the wireless terminal 5 and the print control server 1. If an error that can be detected by the print control server 1 occurs in the process so far, error information is transmitted from the print control server 1 to the wireless terminal 5 based on HTTP. The error information includes the content and cause of the error. In addition, an error that can be detected by the virtual printer 53 may occur in the process so far. For example, as described above, when a response to a message transmitted from the virtual printer 53 to the print control server 1 based on XMPP does not return to the virtual printer 53 within a predetermined time, the XMPP communication unit 532 detects an error. Based on the error information acquired from the print control server 1 and the errors detected by the HTTP communication unit 531 and the XMPP communication unit 532, the trial result notification unit 533 of the virtual printer 53 displays the content and cause of the error on the screen of the wireless terminal 5. Is displayed (S107).

  If no error has occurred in the process so far, by connecting a printer corresponding to the virtual printer 53 to the LAN to which the wireless terminal 5 is connected, the printer can execute printing using e-mail. Is possible. An error caused by the setting of the proxy server 4 can be foreseen by those who are familiar with the setting, but cannot be foreseen by those who are not. Accordingly, there is a problem that even if the printer specification is read, it may not be possible to determine whether or not the printer can actually be used using e-mail. The printing trial method described so far solves such a problem. The process described below allows users to determine how their printers will operate and whether they can print correctly in the format of the data they want to print when a particular printer is installed in a communication environment that can be used using e-mail. It is carried out to make prior confirmation.

  In order to confirm how a printer operates when a specific printer is installed in a communication environment that can be used using e-mail, first, an e-mail as a print request corresponding to the virtual printer 53 is sent. Transmit (S109). Specifically, an e-mail including a text or an attached file to be printed is generated using the wireless terminal 5, and the generated e-mail is transmitted as a print request to an e-mail address assigned to the virtual printer 53.

When an e-mail as a print request is transmitted, the print request receiving unit 12 receives this and requests the print data management unit 14 to generate a print job (S303).
When generation of a print job is requested, the print data management unit 14 extracts the text and an attached file in a predetermined format from the email as print targets, and sets a job ID for each file for the extracted print targets. Give. Subsequently, the print data management unit 14 specifies the internal ID and model ID of the virtual printer 53 corresponding to the e-mail address that is the destination of the e-mail, and supports each of the print targets on the virtual printer 53 based on the model ID. The print data is converted into print data corresponding to the model to be used, and the print data is stored as a print job of the virtual printer 53 by associating it with the internal ID and job ID of the virtual printer 53 (S401).

  Here, when a file in a format that is not supported by the model corresponding to the virtual printer 53 is to be printed, the print data management unit 14 does not generate a print job, but passes the print request reception unit 12. To notify the virtual printer 53 of the error. The virtual printer 53 displays an error on the screen of the wireless terminal 5 based on the notified error. Thus, the user can confirm what format data is not processed as a print target.

  The print data management unit 14 that stores the print job notifies the job notification unit 13 of the occurrence of the print job together with the internal ID and job ID of the printer 3 (S403).

  The job notification unit 13 notified of the occurrence of the print job notifies the virtual printer 53 of the occurrence of the print job by transmitting the print job information using XMPP (S503).

  The virtual printer 53 notified of the generation of the print job sends the print data including the job ID to the print control server 1 by using HTTP, and requests the print data management unit 14 for the print data (S111).

  The print data management unit 14 that has requested the print data transmits the print data to the virtual printer 53 using HTTP (S405).

  The virtual printer 53 that has acquired the print data generates a preview image based on the print data, and displays the preview image on the screen of the wireless terminal 5 (S113). As a result, the user can confirm how the print target included in the e-mail as the print request is printed. For example, when an image having a printing range larger than the paper size supported by the model corresponding to the virtual printer 53 is to be printed, a preview image in a state where a part of the image is cut is generated.

  According to the embodiment described above, since the wireless terminal 5 is virtualized as the virtual printer 53 and communicates with the print control server in the same manner as an existing printer using a temporary identifier corresponding to the virtual printer 53, it is actually assumed. It is possible to test whether the printer and the print control server 1 can communicate normally under certain conditions.

3. Other Embodiments The technical scope of the present invention is not limited to the above-described embodiments, and various modifications are made within the scope not departing from the gist of the present invention, such as appropriately combining the following modifications. Of course you get.
For example, in the above-described embodiment, the internal ID, the XMPP login password, and the e-mail address are transmitted from the print control server 1 to the wireless terminal 5 as the identifier of the virtual printer 53. However, the present invention is not limited to this. Any identifier created in any way may be used. For example, only the internal ID may be transmitted as the identifier of the virtual printer 53. Even when the virtual printer 53 and the print control server 1 communicate with each other based on a plurality of protocols, it is possible to automatically generate identifiers suitable for each protocol individually from one identifier.

  In the above-described embodiment, the example in which the function of the print control server 1 is realized by a single server computer has been described. However, the print control server 1 may be configured by a plurality of physically independent server computers.

In addition, as a communication protocol between the printer 3 and the wireless terminal 5 and the print control server 1, a bidirectional communication protocol such as Telnet or WebSocket may be used instead of XMPP, or another communication protocol replacing HTTP or SMTP may be used. It may be used.
In addition, the communication result may be notified to the user in any form such as text, image, sound, vibration, etc., as long as the user can identify whether an error has occurred or the communication has been successfully performed.
Further, instead of generating a preview image by the virtual printer 53, the print data management unit 14 may generate a preview image. In this case, the virtual printer 53 makes a temporary registration request including information indicating that the virtual printer 53 is a virtual printer, and the registration unit 11 performs registration including information indicating that the virtual printer 53 is a virtual printer. The print data management unit 14 determines whether the data transmission destination is an actual printer or a virtual printer based on whether information indicating that the data is a virtual printer is registered. A preview image is generated instead of print data. Since the preview image can have a smaller data amount than the print data, the communication amount can be reduced by doing so.
Further, in response to the user instructing the wireless terminal 5 to end the trial, the wireless terminal 5 requests the registration unit 11 to delete the registration information regarding the virtual printer 53 and deletes the virtualization program from the wireless terminal 5. You may go. In this case, when receiving a registration information deletion request, the registration unit 11 deletes information regarding the virtual printer 53.
