DETAILED DESCRIPTION
Hereinafter, a form for carrying out the present disclosure (henceforth an “embodiment”) is explained with reference to drawings.
FIG. 1 is a functional block diagram illustrating schematic structure of image forming system 1 according to the present embodiment. As shown in the illustration, image forming system 1 includes image forming apparatus 10, PC 60, and authentication server 90, which are mutually-connected via network 2.
Image forming apparatus 10 has cooperation platform processing part 20 that realizes system extensibility. Image forming apparatus 10 can cooperate with various apparatus as PC 60 or the other networks is a center.
PC 60 has client driver 70 for using image forming apparatus 10. Also, authentication server 90 performs authenticating process when there is access from PC 60 to image forming apparatus 10. Generally, image forming apparatus 10 receives print data from client driver 70 in PC 60. In this case, when a process is required to be authenticated, image forming apparatus 10 transmits user information included in the received print data to authentication server 90 with an authentication request. Authentication server 90 notifies an authentication notification to image forming apparatus 10 when the user information is registered as authentication possible. Image forming apparatus 10 that has received the authentication notification executes an output process of the print data from PC 60.
FIG. 2 is a functional block diagram illustrating schematic structure of image forming apparatus 10. FIG. 2 is mainly indicated with paying attention to a direct printing process. For a configuration about other processes, illustration and explanation are omitted, suitably.
Image forming apparatus 10 is an MFP, for example. Image forming apparatus 10 includes control part 12, operation part 14, display part 16, printing executive operation part 30, image reading part 40, and communication interface 50.
Operation part 14 is a user interface having specific feature buttons, such as execution keys, numeric keypads, or the like. Display part 16 is configured with a liquid crystal panel, or the like, and displays an operating state, or the like. In addition, a touch key, which operation part 14 and display part 16 are combined and built, or the like, may be used.
Printing executive operation part 30 has general printing execution functions. Printing executive operation part 30 executes the print operation with an instruction from control part 12.
Image reading part 40 is a general configuration that can read a manuscript with A3 size or A4 size, for example. Image reading part 40 includes a scanner, platen glass, a manuscript reading slit, a manuscript sheet feeding device, or the like.
Control part 12 is an information processing part including a non-transitory recording medium. Control part 12 performs various kinds of processes. Here, control part 12 has main control part 19 as a function to perform generalized processing in image forming apparatus 10. Also, control part 12 has cooperation platform processing part 20 as a distinctive configuration in the present embodiment.
Cooperation platform processing part 20 includes cooperation platform 22 and cooperation application 23.
Cooperation platform 22 is a solution platform based on internet standard technologies, such as a web browser and a web service.
Cooperation application 23 is application that works on cooperation platform 22. Cooperation application 23 enables network cooperation with PC 60 or other apparatuses by using function of image forming apparatus 10.
Cooperation platform processing part 20, when a printing process from PC 60 is received, performs extended authentication as described later by using cooperation application 23. In detail, virtual direct printing port 24 is used. Thereby, direct printing, what is called, is realized. In order to realize direct printing, cooperation application 23 has a virtual direct printing port (henceforth “virtual direct printing port 24”). When the print data that specified the virtual direct printing port 24 are received, print data are transmitted to actual direct printing port 54 after authentication by authentication server 90.
Communication interface 50 is an interface for communicating with an external apparatus. Communication interface 50 includes a LAN interface, a USB interface for local connection, or the like. Here, it explains with assuming the LAN interface.
Communication interface 50 has printing interface 52 that receives data about printing from PC 60, or the like. The data about printing is print data, printing instructions, or the like. Printing interface 52 has direct printing port 54. Direct printing port 54 has RAW port 56 and IPP (Internet Printing Protocol) port 58.
Generally, when direct printing is performed, direct submission of the print data is performed from client driver 70 in PC 60 to direct printing port 54 in image forming apparatus 10. In this case, the RIP (Routing Information Protocol) component, which image forming apparatus 10 has, analyzes certification information included in printable data (the print data.) Then, the process, which a RIP component authenticates as needed, is executed.
However, it differs in the printing process by using cooperation application 23 in cooperation platform processing part 20. In this case, cooperation application 23 bears duty of the authentication about access from PC 60 to image forming apparatus 10. Therefore, the above-mentioned process, that is, the process that the RIP component analyzes certification information and authenticates, does not work.
Consequently, when executing direct printing in an environment where cooperation application 23 that performs extended authentication is worked, processing with authentication server 90 is performed as follows. Thereby, with authentication, direct printing becomes realizable.
FIG. 3 shows a chart figure illustrating process of a case where client driver 70 in PC 60 performs the direct printing process accompanied by authentication in the environment where cooperation application 23 is worked.
In the environment where cooperation application 23 is operated, client driver 70 in PC 60 starts the execution of the printing process. Then, client driver 70 calls authentication module 72 (authentication interface,) which is used in a case of requiring authenticating process to authentication server 90 (S1).
Authentication module 72 requires authentication by using a web service to authentication server 90 (S2).
When authentication is successful, client driver 70 transmits the print data for performing a print by using direct printing port 54 to cooperation platform 22 in image forming apparatus 10 (S3).
Cooperation platform 22, in detail, which is virtual direct printing port 24 in cooperation application 23, transmits the received data. That is, cooperation application 23 transmits the received data to cooperation application 23 by using the web service, which acts as a host (S4).
In the case, the job name in the print data is changed into a unique name. This is because of enabling pursuit of the job. The unique name is made by virtual direct printing port 24 generating a unique GUID (Globally Unique Identifier.) Also, the information of a login user name is acquired by the print data. This is for identifying who executes the job.
Next, virtual direct printing port 24 transmits set information (“data 1,”) which is the unique job name and the login user name, to authentication server 90 (S5).
Cooperation application 23 transmits the received print data to direct printing port 54 (RAW port 56, or the like,) internally (S6).
At this time, certification information, such as the user name, is excluded in the print data. If the certification information is previously deleted by cooperation application 23, the received print data is transmitted to direct printing port 54 as it is. If the certification information is included in the print data received from cooperation application 23, cooperation application 23 performs process to exclude the certification information. This is, if the certification information is included in the print data, a same process as the authenticating process in a normal direct printing process is accomplished, uselessly. Supposing, if disqualified certification information in authentication of the normal direct printing process remains, authentication is not be performed. In order to avoid the situation, the certification information is deleted. Here, this is because ensuring security by internal process can be estimated.
In addition, as replacing with the process that excludes certification information, a process for rewriting or a process for adding another certification information may be accomplished. Another certification information is suitable certification information for the authenticating process used for direct printing port 54. This can raise security.
Then, image forming apparatus 10 executes an event. That is, image forming apparatus 10 outputs the acquired print data from printing executive operation part 30.
Cooperation application 23 receives event information (a start, an end, or the like) in the job (print job) performed in image forming apparatus 10. Cooperation application 23 notifies event information with the job name to authentication server 90 (S7).
Authentication server 90 compares above-mentioned data and the transmitted event. Authentication server 90 determines and records whose job it is (S8).
As mentioned above, according to the present embodiment, extended authentication by using cooperation platform processing part 20 (cooperation platform 22, cooperation application 23) is performed. In this environment, even if in a case where image forming apparatus 10 has a request of a direct printing process from PC 60, the direct printing process that performs suitable authentication is realizable.
As explained in detail, in a typical case, a printout is performed from a driver for printing installed in PC to the image forming apparatus on a network. In this case, the direct printing that transmits print data to a RAW port, or the like, by using an interface by a standard TCP/IP port may be used. At this time, when the cooperation platform of the image forming apparatus performs extended authentication, an application on a cooperation platform authenticates by substituting authentication function to be primarily-implemented in the image forming apparatus. In this case, the problem is happened that direct printing by using an authentication server cannot be executed.
However, in the typical case, there is no technology supposing the cooperation platform, and another technology is required.
As compared with this, according to the present disclosure, even if in a case where it indicates to execute the job of direct printing to the application that works on a specific platform, in an image forming apparatus, direct printing including authentication can be executed, appropriately.
As the above, the present disclosure is explained based on the embodiment. This embodiment is an exemplification, and various modifications about the combination of each of those components are possible for it. Also, it is understood by the person skilled in the art that such a modification is also in the range of the present disclosure.
