This application claims priority from Japanese Patent Application No. 2018-118905 filed Jun. 22, 2018. The entire content of the priority application is incorporated herein by reference.
The present disclosure relates to a server that generates a file based on a file received from a terminal device and transmits the generated file to a communication apparatus.
A conventional mediation server receives image data from a mobile device and controls a multifunction peripheral (MFP) to print an image based on this image data. Specifically, the mediation server transmits to the MFP a QR code (registered trademark) that includes a job ID to the MFP in response to a request from the MFP. The MFP displays this QR code. Using a reading unit of the mobile device, the user of the device scans the QR code displayed on the MFP to acquire the job ID. After acquiring the job ID, the mobile device transmits an upload request to the mediation server that includes image data and the job ID. After the image data has been uploaded to the mediation server, the MFP transmits an image data acquisition request including the job ID to the mediation server and subsequently receives the image data from the mediation server and prints the image based on the image data.
In the conventional technique, an MFP different from the MFP that acquired the job ID from the mediation server cannot receive the image data from the mediation server since the different MFP does not know the job ID.
In view of the foregoing, it is an object of the present disclosure to provide a technology in which a server that receives a first file from a terminal device and transmits a second file obtained based on the first file to any of two or more communication apparatuses included in a certain group.
In order to attain the above and other objects, the disclosure provides a server. The server includes a communication interface, a memory, and a processor. The communication interface is configured to communicate with a terminal device. The memory stores first correlation information for correlating first group identification information with both first device information and second device information. The first group identification information is for identifying a first group. The first device information is assigned to a first communication device. The second device information is assigned to a second communication device. The first correlation information indicates that the first group includes the first communication device and the second communication device. The processor is configured to perform: receiving the first group identification information and a first file from the terminal device; in a first case where the first group identification information and the first file are received from the terminal device: storing in the memory the first file and first authentication information to correlate both the first file and the first authentication information with the first group identification information; and transmitting the first authentication information to an external apparatus via the communication interface; in a second case where device information matching the first device information correlated with the first group identification information and authentication information matching the first authentication information are received from the first communication device via the communication interface after the transmitting the first authentication information is performed, transmitting to the first communication device a second file generated using the first file which is stored correlated with the first authentication information in the memory; and in a third case where device information matching the second device information correlated with the first group identification information and authentication information matching the first authentication information are received from the second communication device via the communication interface after the transmitting the first authentication information is performed, transmitting to the second communication device the second file.
According to another aspect, the disclosure provides a non-transitory computer readable storage medium storing a set of program instructions for a server. The server includes a communication interface configured to communicate with a terminal device, and a memory storing first correlation information for correlating first group identification information with both first device information and second device information. The first group identification information is for identifying a first group. The first device information is assigned to a first communication device. The second device information is assigned to a second communication device. The first correlation information indicates that the first group includes the first communication device and the second communication device. The set of program instructions includes: receiving the first group identification information and a first file from the terminal device; in a first case where the first group identification information and the first file are received from the terminal device: storing in the memory the first file and first authentication information to correlate both the first file and the first authentication information with the first group identification information; and transmitting the first authentication information to an external apparatus via the communication interface; in a second case where device information matching the first device information correlated with the first group identification information and authentication information matching the first authentication information are received from the first communication device via the communication interface after the transmitting the first authentication information is performed, transmitting to the first communication device a second file generated using the first file which is stored correlated with the first authentication information in the memory; and in a third case where device information matching the second device information correlated with the first group identification information and authentication information matching the first authentication information are received from the second communication device via the communication interface after the transmitting the first authentication information is performed, transmitting to the second communication device the second file.
The particular features and advantages of the disclosure as well as other objects will become apparent from the following description taken in connection with the accompanying drawings, in which:
Structure of a Communication System 2
The LAN 4 is further connected to an Internet 6. The mediation server 10 is provided on the Internet 6. A device connected to the LAN 4 (e.g., the management terminal 500) can communicate with servers on the Internet 6 (e.g., the mediation server 10) through the LAN 4 and Internet 6.
The printers 100-300 are peripheral devices (devices peripheral to the management terminal 500) that can implement printing functions. Media Access Control (MAC) addresses are assigned to the printers 100-300. Specifically, the MAC address MA1 is assigned to the printer 100, the MAC address MA2 is assigned to the printer 200, and the MAC address MA3 is assigned to the printer 300.
Structure of the Mediation Server 10
The mediation server 10 is provided on the Internet 6 by the vendor of the printer 100 and the like. The mediation server 10 mediates communications necessary for printing images between terminal devices (e.g., the user terminal 600) and printers (e.g., the printer 100). Specifically, the mediation server 10 receives a file representing an image from a terminal device, converts the file to image data in a data format that a printer can interpret, and transmits the print data to the printer. Implementing these processes with the mediation server 10 eliminates the need to install driver programs on the terminal devices.
The mediation server 10 is provided with a network interface 12, and a control device 20. The network interface 12 is connected to the Internet 6. The control device 20 is provided with a CPU 22, and a memory 24. The memory 24 is configured of volatile memory, nonvolatile memory, and the like. The memory 24 stores a program 26, a group table 30, an individual table 32, and a job table 34. The CPU 22 executes various processes according to the program 26 stored in the memory 24.
The group table 30 is used to manage groups that include two or more printers. Specifically, for each of one or more groups, the group table 30 stores a record including a group identifier (group ID), an email address, and a list of two or more MAC addresses so that the group ID, the email address, and the list of two or more MAC addresses are correlated with one another. The group identifier (group ID) is for identifying the group. The email address is an email address of the user managing the group. The two or more MAC addresses are assigned to the two or more printers in the group. The mediation server 10 generates the group ID. When a MAC address is received from a printer together with a registration code, the mediation server 10 stores the MAC address in a corresponding record of the group table 30. This process will be described later with reference to
The individual table 32 is used to provide individual identification information that identifies a single printer only. Specifically, for each of one or more printers, the individual table 32 stores a record including an individual ID for identifying only that printer, and the MAC address assigned to that printer so that the individual ID and the MAC address are correlated with each other. The mediation server 10 generates the individual IDs. When a MAC address is received from a printer, the mediation server 10 stores this MAC address in a corresponding record of the individual table 32. This process will be described later with reference to
For each of one or more print jobs, the job table 34 stores a record including a group ID or an individual ID, a job ID, the filename of the file, print settings information, and a password so that the group ID or the individual ID, the job ID, the filename, and the password are correlated with one another. Here, the group ID or the individual ID is for identifying a group of printers or an individual printer to be used for executing the print job. The job ID is for identifying the print job. The filename of the file includes image data representing the image to be printed according to the print job. The print settings information specifies print settings for executing the print job (paper size, color, copies, duplex option, and the like). The mediation server 10 generates the job ID and the password. When a file and print settings information are received from a terminal device, the mediation server 10 stores the filename and print settings information in a record of the job table 34. This process will be described later with reference to
Group Registration Process
Next, a process for registering MAC addresses in association with a group ID will be described with reference to
In T10 of
After the user of the management terminal 500 has created a group registration email in T10, in T12 the management terminal 500 transmits the group registration email to a mail server (not shown). Thereafter, the mail server transmits the group registration email to the mediation server 10 specified by the domain name in the destination address “group@server.com.”
Upon receiving the group registration email from the management terminal 500 in T12, in T14 the mediation server 10 generates a registration code “abcde” in conformance with the command “group” in the destination address “group@server.com.” The mediation server 10 stores the generated registration code “abcde” in the memory 24 in association with the source address “admin2@mail.com” which is included in the group registration email.
In T16 the mediation server 10 generates a code notification email for notifying the management terminal 500 of the registration code. The code notification email includes the destination address “admin2@mail.com,” the source address “complete@server.com,” and a message body including the registration code “abcde.” Here, the source address “complete@server.com” is constructed from the character string “complete” specifying that the registration code “abcde” has been stored, and the domain name of the mediation server 10 “server.com.”
In T18 the mediation server 10 transmits the code notification email to the mail server. Since account information of the address “admin2@mail com” is stored in the mail program on the management terminal 500, the management terminal 500 can use the mail program to receive the code notification email from the mail server.
After receiving the code notification email from the mediation server 10 in T18, in T20 the management terminal 500 displays this code notification email. From this display, the user can note the registration code “abcde.”
In T30 the user performs a prescribed operation on the printer 100 for adding the printer 100 to a group. In T32 the printer 100 displays a registration screen SC1 for entering a registration code. In T34 the user inputs the registration code “abcde” in an entry field provided in the registration screen SC1. In T36 the printer 100 transmits the inputted registration code “abcde” and the MAC address MA1 of the printer 100 to the mediation server 10.
When the mediation server 10 receives the registration code “abcde” and the MAC address MA1 from the printer 100 in T36, in T38 the mediation server 10 identifies the address “admin2@mail.com” stored in the memory 24 in association with the registration code “abcde.” Since a group ID is not currently stored in the group table 30 in association with the address “admin2@mail.com,” the mediation server 10 generates a new group ID “g02.” In T40 the mediation server 10 registers in the group table 30 a record including the newly generated group ID “g02”, the identified address “admin2@mail.com”, and the MAC address MA1.
In T41 the mediation server 10 generates a URL notification email for notifying the user of the group URL “http://server.com/g02” that includes the group ID “g02.” The group URL “http://server.com/g02” is used to access the mediation server 10 in order to register information (a record) for a print job (job ID, filename, etc.) in association with the group ID “g02.” The URL notification email includes the destination address “admin2@mail.com,” the source address “register@server.com,” and a message body providing the group URL “http://server.com/g02.” The address “register@server.com” is constructed from the character string “register” indicating that the MAC address MA1 has been registered, and the domain name of the mediation server 10 “server.com.”
In T42 the mediation server 10 transmits the URL notification email to the mail server. As described in T18, the management terminal 500 can use the mail program to receive the URL notification email from the mail server.
After receiving the URL notification email from the mediation server 10 in T42, in T44 the management terminal 500 displays the URL notification email. From this display, the user of the management terminal 500 can note the group URL “http://server.com/g02.”
Next, the user performs an operation on the printer 200 for adding the printer 200 to the group. In response, the printer 200 executes the same process described in T30-T34, and in T56 transmits the registration code “abcde” and the MAC address MA2 of the printer 200 to the mediation server 10.
After receiving the registration code “abcde” and the MAC address MA2 from the printer 200 in T56, in T60 the mediation server 10 identifies the address “admin2@mail.com” stored in the memory 24 in association with the registration code “abcde”, and identifies the group ID “g02” stored in the group table 30 in association with the identified address “admin2@mail.com.” Next, the mediation server 10 registers the MAC address MA2 in the record of the group table 30 so that the MAC address MA2 is in association with the group ID “g02” and the address “admin2@mail.com.” Consequently, the two MAC addresses MA1 and MA2 are now stored in the record of the group table 30 in association with the group ID “g02.”
A possible comparative example would be to provide the management terminal 500 with a prescribed screen that includes buttons for transmitting requests to the mediation server 10 requesting the mediation server 10 to generate a group ID and to register a MAC address instead of performing T10 and T12. In this case, when the mediation server 10 receives a request from the management terminal 500 in response to the user selecting a button in the prescribed screen, the mediation server 10 transmits a registration code to the management terminal 500. In contrast, the user of the management terminal 500 in the embodiment can acquire a registration code by transmitting a group registration email and receiving a code notification email. In other words, group IDs can be generated and MAC addresses can be registered without providing the management terminal 500 with a prescribed screen for requesting the mediation server 10 to generate a group ID and register a MAC address. The configuration of the comparative example described above may be employed as a variation of the embodiment.
Job Registration Process for a Group
Next, a job registration process for recording information on a print job (job ID, filename, etc.) in the job table 34 in association with a group ID will be described with reference to
In T100 a user wishing to print an image inputs the group URL “http://server.com/g02” into the user terminal 600.
In T102 the user terminal 600 transmits a Hypertext Transfer Protocol (HTTP) request to the mediation server 10. The HTTP request includes the group URL “http://server.com/g02” inputted in T100.
When the mediation server 10 receives the HTTP request with the group URL from the user terminal 600 in T102, in T104 the mediation server 10 transmits print settings screen data representing a print settings screen SC2 to the user terminal 600. In T104, the mediation server may transmit the group ID “g02” together with the print settings screen data. The print settings screen SC2 includes a selection field for selecting a file to be printed, and entry fields for inputting print settings (paper size, etc.).
When the user terminal 600 receives the print settings screen data from the mediation server 10 in T104, in T106 the user terminal 600 displays the print settings screen SC2. In T108 the user selects a file to be printed from among one or more files stored on the user terminal 600 (the file having filename “file2.pdf” in this example) and inputs print settings information SI2 in the entry fields of the print settings screen SC2. In T110 the user terminal 600 transmits a job registration request including the inputted information to the mediation server 10. In this case, the job registration request includes the file having filename “file2.pdf,” the print settings information SI2, and the group ID “g02.” The job registration request is a command for requesting the mediation server 10 to record information for the print job.
After the mediation server 10 receives the job registration request from the user terminal 600 in T110, in T112 the mediation server 10 generates a job ID “j002” and stores the file in the job registration request having the filename “file2.pdf” in the memory 24. In T114 the mediation server 10 executes a password generation process described later (see
Upon receiving the password “YYY” from the mediation server 10 in T116, in T118 the user terminal 600 displays the password “YYY” so that the user can learn the password.
Password Generation Process
Next, a password generation process for generating a password will be described with reference to
In S12 the mediation server 10 determines whether there exist in the group table 30 one or more group IDs identifying a group includes one or more of the target MAC addresses. Here, in a case where the target ID is the group ID, the mediation server 10 determines whether there exist in the group table 30 one or more group IDs which are different from the target ID and identify a group includes one or more of the target MAC addresses. The mediation server 10 advances to S14 when determining that such a group ID exists (S12: YES) and skips S14 to advance directly to S16 when such a group ID does not exist (S12: NO). In the example of
In S14 the mediation server 10 identifies from the job table 34 the password associated with the group ID identified in S12. In the example of
In S16 the mediation server 10 determines whether the individual table 32 includes at least one or more individual IDs associated with the one or more target MAC addresses. Here, in a case where the target ID is the individual ID, the mediation server 10 determines whether the individual table 32 includes at least one or more individual IDs which is different from the target ID and associated with the one or more target MAC addresses. The mediation server 10 advances to S18 when determining that there is at least one individual ID associated with one of the target MAC addresses (S16: YES) and skips S18 to advance to S20 when determining that there are no individual IDs associated with any of the target MAC addresses (S16: NO). In the example of
In S18 the mediation server 10 identifies the password in the job table 34 associated with the individual ID identified in S16. In the case of
In S19 the mediation server 10 identifies the password in the job table 34 associated with the target ID. In the case of
In S20 the mediation server 10 generates a password that does not match any of the passwords identified in S14, S18, and S19. In the case of
As in the example of the group table 30 in
Further, the MAC address MA1 of the printer 100 may be associated with an individual ID (such as the ID “s01” described later) in addition to being associated with the group ID “g01.” Executing the process in
Job Registration Process for an Individual Printer
Next, a job registration process for registering in the job table 34 a record for a print job which associates a job ID, a filename, and etc. with an individual ID will be described with reference to
In T200 of
In T204 the user selects the How to Use button BT1 in the menu screen SC3. In this case, in T206 the printer 100 transmits a URL request to the mediation server 10 that includes the MAC address MA1 of the printer 100. The URL request is a command for requesting an individual URL including an individual ID.
When the mediation server 10 receives the URL request from the printer 100 in T206, in T208 the mediation server 10 generates an individual ID “s01” and registers in the individual table 32 a record including the individual ID “s01”, and the MAC address MA1 included in the URL request. If the record having the MAC address MA1 and the individual ID “s01” is already stored in the individual table 32 at this time, the mediation server 10 uses the individual table 32 to identify the individual ID “s01” correlated with the MAC address MA1 included in the URL request. In this case, the identified individual ID “s01” is used in the subsequent step T210.
In T210 the mediation server 10 transmits an individual URL “http://server.com/s01” that includes the generated individual ID “s01” to the printer 100. The individual URL “http://server.com/s01” is used to access the mediation server 10 in order to register a record for a print job which associates a job ID, a filename, and etc. with the individual ID “s01.” Upon receiving this individual URL, in T212 the printer 100 displays the individual URL “http://server.com/s01.” In T212 the printer 100 may display a message for prompting a user to access the mediation server 10 using the individual URL “http://server.com/s01” for registering a print job.
Step T230 is identical to step T100 of
When the mediation server 10 receives the job registration request from the user terminal 600 in T240, in T242 the mediation server 10 generates a job ID “j003.” In T244 the mediation server 10 executes the password generation process described in
Here, the process of generating the password “ZZZ” will be described in greater detail with reference to
Printing Process for a Group
Next, various examples of printing processes will be described with reference to
Case A1 for Inputting the Password “YYY” into the Printer 100
Steps T300 and T302 are identical to steps T200 and T202 of
When the mediation server 10 receives the data request from the printer 100 in T306, in T308 the mediation server 10 identifies the group ID and the individual ID in the group table 30 and the individual table 32 associated with the MAC address MA1 in the data request. In this case, the mediation server 10 identifies group IDs “g01” and “g02” from the group table 30 (see
In T310 the mediation server 10 identifies the three passwords “XXX,” “YYY,” and “ZZZ” in the job table 34 associated with the group IDs “g01” and “g02” and the individual ID “s01” identified in T308, and determines that the password “YYY” associated with the group ID “g02” among the identified passwords matches the password “YYY” included in the data request. In this case, in T312 the mediation server 10 identifies the various data in the job table 34 associated with the password “YYY” (i.e., the job ID “j002,” the filename “file2.pdf,” and the print settings information SI2). Next, the mediation server 10 converts the file having filename “file2.pdf” according to the print settings specified in the identified print settings information SI2 to generate print data PD2 having a data format that the printer 100 can interpret.
In T316 the mediation server 10 transmits the generated print data PD2 to the printer 100. As a result, in T318 the printer 100 prints an image represented by the print data PD2 (i.e., an image represented by the file having filename “file2.pdf”).
In addition, after transmitting the print data PD2 to the printer 100, in T314 the mediation server 10 deletes the record having the job ID “j002” from the job table 34. Subsequently, the mediation server 10 deletes the file having filename “file2.pdf” from the memory 24.
Case A2 for Inputting the Password “YYY” into the Printer 200
In Case A2 the password “YYY” is inputted into the printer 200 by executing the same process in T300-T304 in Case A1 described above. Step T326 is identical to step T306 of Case A1, except that in T326 the data request includes the MAC address MA2 of the printer 200. Step T328 is identical to step T308, except that in T328 the mediation server 10 identifies the group ID “g02” associated with the MAC address MA2 included in the data request. Steps T330-T338 are identical to steps T310-T318 described above.
Case A3 for Inputting the Password “YYY” into the Printer 300
In Case A3 the password “YYY” is inputted into the printer 300 by executing the same process in T300-T304 described above. Step T346 is identical to step T306 of Case A1, except that in T346 the data request includes the MAC address MA3 of the printer 300. In this case, since there are no group IDs or individual IDs associated with the MAC address MA3 in the data request, in T350 the mediation server 10 determines that a password matching the password “YYY” in the data request does not exist. Hence, in T356 the mediation server 10 transmits an error notification to the printer 300 indicated that a password matching the password “YYY” does not exist.
In Cases A1-A3 described above, the group ID “g02” is stored in the group table 30 in association with the two MAC addresses MA1 and MA2 (see
Printing Process for an Individual Printer
Next, various cases of printing processes for executing printing operations using the password “ZZZ” associated with the individual ID “s01” will be described with reference to
Case B1 for Inputting the Password “ZZZ” into the Printer 100
In the beginning of Case B1 of the printing process, the same process in T300 and T302 of
Case B2 for Inputting the Password “ZZZ” into the Printer 200
In Case B2 of the printing process, the password “ZZZ” is inputted into the printer 200 by executing the same process described in T300, T302 of
In Cases B1 and B2 described above, the individual ID “s01” is stored in the individual table 32 in association with the MAC address MA1 (see
Here, the processes performed by the mediation server 10 from receiving a file to transmitting print data will be compared for the case of a group and the case of an individual printer. As illustrated in

Group Registration Process
In the second embodiment, the group table 30 stores a storage date and time indicating when a MAC address was stored in the group table 30 for each of the one or more MAC addresses included in the list of MAC addresses. For example, the storage date and time “8:00” is stored in the group table 30 in association with the MAC address MA1 to indicate the time that the MAC address MA1 was registered in the record having the group ID “g02.” Note that since the date is common for all storage date and times in the second embodiment, the date is omitted in the storage date and times in the following explanation and
A storage date and time is also registered in a record of the job table 34 to indicate when the record including the job ID and password were registered. As an example, the storage date and time “9:50” is stored in the record of the job table 34 having the group ID “g02,” the job ID “j002,” and the password “YYY.”

Printing Process
Next, various cases of a printing process will be described with reference to
Case C1 for Inputting the Password “YYY” into the Printer 300
At the beginning of Case C1, the same process described in T300 and T302 of
In T611 the mediation server 10 identifies the storage date and time “9:50” in the job table 34 associated with the password “YYY” and identifies the storage date and time “10:30” in the group table 30 associated with both the group ID “g02” and the MAC address MA3. By comparing the two storage date and times “9:50” and “10:30,” the mediation server 10 determines that the time “9:50” at which the password “YYY” was stored in the job table 34 in association with the group ID “g02” is earlier than the time “10:30” at which the MAC address MA3 was stored in the group table 30 in association with the group ID “g02.” In this case, in T616 the mediation server 10 transmits an error notification to the printer 300, and does not transmit print data to the printer 300.
Case C2 for Inputting the Password “VVV” into the Printer 300
In Case C2, the same process described in T300 and T302 of
In T631 the mediation server 10 identifies the storage date and time “10:00” in the job table 34 associated with the password “VVV” and identifies the storage date and time “9:00” in the group table 30 associated with both the group ID “g03” and the MAC address MA3. By comparing the two storage date and times “10:00” and “9:00,” the mediation server 10 determines that the time “10:00” at which the password “VVV” was stored in the job table 34 in association with the group ID “g03” is later than the time “9:00” at which the MAC address MA3 was stored in the group table 30 in association with the group ID “g03.” In this case, the mediation server 10 executes the process in T632-T636. Step T632 is identical to step T312 of
According to Case C1 described above, after the password “YYY” was stored in the job table 34 in association with the group ID “g02”, the MAC address MA3 of the printer 300 was stored in the group table 30 in association with the group ID “g02”. Subsequently, the mediation server 10 receives the password “YYY” from the printer 300 (T606). In this case, the mediation server 10 does not transmit the print data PD4 to the printer 300 (T616). As illustrated in an initial state of the group table 30 in
While the disclosure has been described in detail with reference to the above embodiments, it would be apparent to those skilled in the art that various changes and modifications may be made thereto.
