Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present disclosure relates to information processing systems, information processing methods, and recording media. 
         [0003]    2. Description of the Related Art 
         [0004]    Pull-print is known as a, printing method. In the pull-print, a user transmits printing data to a certain server by using, for example, a Personal Computer (PC). The server stores the printing data. An image forming apparatus acquires (pulls) the printing data from the server to execute a printing job, where the server has been set to be a reference storage (a connection destination) of the image forming apparatus. By using the pull-print, the printing job is executed when the user is near the image forming apparatus. Therefore, it can be prevented that a sheet on which classified information is printed is left, or seen by someone else. Also, by using the pull-print, a plurality of image forming apparatuses, whose reference storage are the same server, can execute printing jobs with respect to the same printing data. 
         [0005]    In the pull-print, a subject for performing processes on the printing data is divided into the server and the image forming apparatus. Consequently, information managed by the server and information managed by the image forming apparatus are generated with respect to the same printing data (or printing job). It is difficult to associate both information items in the conventional technology. 
         [0006]    For example, even if identification information is allocated to respective printing jobs on a PC-by-PC basis, the identification information may be duplicated among the printing data received by the server from the plurality of PCs because the identification information is made unique only in one PC. Therefore, if the information managed by the server and the information managed by the image forming apparatus are associated based on the identification information, the associated information may not relate to the same printing data.

The SD card slot  27  is used for retrieving the program stored in the SD card  80 . That is, in the image forming apparatus  20 , not only the program stored in the ROM  213 , but also the program stored in the SD card  80  can be loaded into the RAM  212  to be executed. Additionally, other recording media (e.g., CD-ROM, USB (Universal Serial Bus), etc.) may be used instead of the SD card  80 . That is, type of the recording medium corresponding to the SD card  80  is not limited. In this case, hardware corresponding to the type of the recording medium may be provided instead of the SD card slot  27 . 
         [0035]      FIG. 4  is a diagram illustrating example functional configurations of the business base server, the authentication server, and the management server. In  FIG. 4 , the authentication server  50  includes an authentication unit  51 . The authentication unit  51  is achieved by processes performed by the CPU included in the authentication server  50  in accordance with one or more programs installed in the authentication server  50 . The authentication server  50  uses a user information storage unit  52 . The user information storage unit  52  can be achieved by an auxiliary storage device of the authentication server  50  or a storage device that can be connected to the authentication server  50  via the network. 
         [0036]    In response to an authentication request transmitted from the business base server  10  or the image forming apparatus  20 , the authentication unit  51  performs authentication of user name and password included in the authentication request. The authentication is performed by comparing the user name and password included in the authentication request with user name and password stored in the user information storage unit  52 . In the user information storage unit  52 , the user name and password, a charge code, attribute information (department name, e-mail address, etc.) related to a user (hereinafter referred to as “user information”) who has been authorized to use the print system  1 , and the like, are recorded, where the respective items described above are recorded on a user-by-user basis. The charge code is identification information indicating type of usage of the image forming apparatus  20 , where the types are associated with respective business operations. Also, the types may be associated with departments, projects related to the user. Therefore, the charge code may be identification information of a department or a project to which the user belongs. For example, a management code is used as identification information for determining charging destination related to usage of functions of the image forming apparatus  20  (job execution). 
         [0037]    Meanwhile, the business base server  10  includes a data reception unit  121 , a rule application unit  122 , a job information generation unit  123 , a job information management unit  124 , a data management unit  125 , a log management unit  126 , and the like. The respective units are achieved by processes performed by the CPU  104  in accordance with the one or more programs installed in the business base server  10 . The business base server  10  also includes a job information storage unit  131 , a data storage unit  132 , a print rule storage unit  133 , a log storage unit  132 , and the like. For example, the respective storage units can be achieved by the auxiliary storage device  102 . Or, the respective storage units may be achieved by a storage device connected to the business base server  10  via the network. 
         [0038]    In response to receiving printing data from the user PC  30 , the data reception unit  121  requests the authentication server  50  to perform the authentication of the user of the user PC  30  that has transmitted the printing data, and receives the authentication result from the authentication server  50 . For example, the data reception unit  121  receives user name and password of the user of the user PC  30  in addition to the printing data, where the user name and password may be included in the printing data. The data reception unit  121  requests the authentication server  50  to perform the authentication of the user name and password. In a case of successful authentication, the user information of the authenticated user is included in the authentication result received form the authentication server  50 . 
         [0039]    The rule application unit  122  determines a print rule for the printing job among print rules stored in the print rule storage unit  133 , thereby applying the determined print rule to the printing data. The print rule means a rule to be applied to a printing job based on the printing data, which includes a conditional equation and a process to be performed upon the conditional equation being satisfied. For example, the conditional equation is an equation expressing condition with respect to values of items constituting the user information, or values of items constituting print attribute included in the printing data. For example, “department=AAA”, “number of pages &gt;20”, etc., are set as the conditional equations. For example, the process to be performed upon the conditional equation being satisfied is a forced change of the print attribute. For example, change into monochrome print, change into double face print or aggregation print, etc., are exemplified as the forced change of the print attribute. 
         [0040]    The job information generation unit  123  analyzes the printing data to generate job information related to the printing data. The job information generation unit  123  stores the printing data in the data storage unit  132 , and also stores the generated job information associated with the printing data in the job information storage unit  131 . 
         [0041]    In response to receiving, from the image forming apparatus  20 , an acquisition request of a list of job information (hereinafter referred to as “job list”) related to user logged-in the image forming apparatus  20 , the job information management unit  124  acquires the job information including the user name that is included in the acquisition request from the job information storage unit  131 . The job information management unit  124  transmits the job list consisting of the acquired job information items to the image forming apparatus  20  that is the request source of the acquisition request. In response to an acquisition request of printing data related to a job information item selected from the job list, the data management unit  125  acquires the printing data from the data storage unit  132 . The data management unit  125  transmits the acquired printing data to the image forming apparatus  20  that is the request source of the acquisition request. 
         [0042]    The log management unit  126  stores log information related to printing data to be processed by the image forming apparatus  20  selected from printing data stored in the data storage unit  132 . For example, job information of the printing data, etc., are included in the log information. 
         [0043]    The management server  40  includes a log unification unit  41 . The log unification unit  41  is achieved by processes performed by the CPU of the management server  40  in accordance with the one or more programs installed in the management server  40 . The management server  40  uses a unified log storage unit  42 . The unified log storage unit  42  can be achieved by the auxiliary storage device of the management server  40 , or a storage unit that can be connected to the management server  40  via the network. 
         [0044]    The log unification unit  41  receives, from the business base server  10 , log information related to the printing datum to be processed in the image forming apparatus  20  selected from printing data stored in the data storage unit  132  of the business base server  10 , and also receives, from the image forming apparatus  20 , log information related to processes having performed with respect to the printing data in the image forming apparatus  20 . The log unification unit  41  associates the log information received from the business base server  10  with the log information received from the image forming apparatus  20  based on identity of related printing data. The associated log information is stored in the unified log storage unit  42 . 
         [0045]      FIG. 5  is a diagram illustrating an example software configuration of the image forming apparatus of the present embodiment. In  FIG. 5 , the image forming apparatus  20  includes standard application package  221 , a SDK application package  222 , a SDK platform  223 , JVM  224 , a control service  225 , an OS  226 , and the like. 
         [0046]    The standard application package  221  is a set of application programs which are normally installed (at time of shipment) in the image forming apparatus  20 . In  FIG. 5 , a scan application  2211 , a print application  2212 , a copy application  2213 , a FAX application  2214  are illustrated as example application programs included in the standard application package  221 .

The print application  2212  executes a printing job of printing data using the printer  23 , etc., in response to the printing data being received at a predetermined port. The copy application  2213  executes a copy job using the scanner  22 , the printer  23 , and the like. The FAX application  2214  executes a FAX transmission job or a reception job using the modem  24 , and the like. 
         [0047]    The control service  225  is a set of software modules for providing functions for controlling hardware resources or functions common to respective application programs with high order programs such as the standard application package  221  and the SDK platform  223 . For example, the control service  225  has a function related to network communication, a function for controlling the scanner  22 , a function for controlling the printer  23 , a function for managing the memory, a function of authentication, and the like. 
         [0048]    The SDK application package  222  is one or more application programs (may be referred to as plug-in) for expanding functions of the image forming apparatus  20 , which are additionally installed after the shipment of the image forming apparatus  20 . In  FIG. 5 , a storage print application  2221  and an extended authentication application  2222  are illustrated as example application programs included in the SDK application package  222 . The storage print application  2221  of the SDK application package  222  is provided for achieving a printing method referred to as storage print or pull-print, and the like. That is, the storage print application  2221  controls execution of printing job regarding the printing data that is transmitted from the user PC  30  to the business base server  10  and stored therein. Additionally, the print application  2221  included in the standard application package  221  is basically designed to execute the printing job regarding the printing data that is transmitted from the user PC  30  to the predetermined port of the image forming apparatus  20 . Therefore, the storage print or pull-print cannot be performed with the print application  2221 . 
         [0049]    The extended authentication application  2222  of the SDK application package  222  is provided for performing user authentication in conjunction with an external authentication apparatus (in this embodiment, authentication server  50 ). Additionally, although the control service  225  has a function of authentication, the function does not support a process required in the present embodiment. Therefore, the extended authentication application  2222  is used in the present embodiment. 
         [0050]    Additionally, the SDK application package  222  may include one or more application programs other than the storage print application  2221  and the extended authentication application  2222 . 
         [0051]    The SDK platform  223  includes an API (Application Program Interface) for developing application program included in the SDK application package  222 , and provides execution environment of the application program included in the SDK application package  222 . For example, the API may be a function, a class defined in object oriented manner, a method of the class, and the like. In the present embodiment, the API is achieved by a group of classes in JAVA. In the following, the API provided by the SDK platform  223  is referred to as “SDKAPI”. For example, the SDK platform  223  provides SDKAPIs related to scanning function and printing function, SDKAPI related to copying function, etc., with the SDK application package  222 . The SDKAPI is published, and a third vender can develop the application program included in the SDK application package  222 . 
         [0052]    The JVM  224  is VM (Virtual Machine) of JAVA. The SDK application package  222  is installed as JAVA application in the present embodiment. The SDK application package  222 , the SDK platform  223 , etc., can use the API provided by a standard classes of JAVA included in the JVM  224 . 
         [0053]    The OS  226  is an OS (Operating System). Software of the image forming apparatus  20  operates as a process or a thread in the OS  226 . 
         [0054]    In the following, a process performed in the print system  1  will be described.  FIG. 6  is a flowchart illustrating a process performed by the business base server  10  in response to receiving the printing data. For convenience of explanation,  FIG. 6  illustrates the process regarding the business base A. In a case where the process illustrated in  FIG. 6  regarding another business base is performed, the PC  30  and the business base server  10   a  described below are replaced with those of the other business base. 
         [0055]    In step S 101 , the data reception unit  121  of the business base server  10   a  receives printing data transmitted from any of the user PCs  30   a . The data reception unit  121  transmits an authentication request including user name and password received with the printing data or included in the printing data to the authentication server  50  (step S 102 ). Additionally, for example, the user of the user PC  30   a  may input user name and password through a screen for setting print attribute (print condition) when performing printing operation. The user name and password input in this way may be received in step S 101 . 
         [0056]    The authentication unit  51  of the authentication server  50  performs the authentication by determining whether a record including the user name and password is stored in the user information storage unit  52 . That is, the authentication unit  51  determines that the authentication is successfully performed in a case where the record is stored in the user information storage unit  52 . In a case of successful authentication, the authentication unit  51  transmits a response including the user information included in the record to the business base server  10   a . On the other hand, in a case of authentication failure, the authentication unit  51  transmits a response including information indicating the authentication failure to the business base server  10   a.    
         [0057]    In a case where the response from the authentication server  50  indicates authentication failure (No in step S 103 ), the data reception unit  121  of the business base server  10   a  terminates the process illustrated in  FIG. 6 . On the other hand, in a case where the response from the authentication server  50  includes the user information (Yes in step S 103 ), the rule application unit  122  determines whether there is any print rule to be applied to the printing data (step S 104 ). For example, when the user information obtained through the successful authentication, the print attribute included in the printing data, etc., satisfies a conditional equation of any of print rules stored in the print rule storage unit  133 , the rule corresponding to the satisfied conditional equation is determined to be applied. 
         [0058]    In a case where there is any print rule to be applied (Yes in step S 104 ), the rule application unit  122  applies the rule to the printing data (step S 105 ). For example, the print attribute of the printing data is forced to be changed. On the other hand, in a case where there is no print rule to be applied (No in step S 104 ), the process of step S 105  is not performed. 
         [0059]    The job information generation unit  123  stores the printing data in the data storage unit  132  (step S 106 ). For example, the printing data is included in a file to be stored. The job information generation unit  123  generates job information related to the printing data (step S 107 ).  FIG. 7  is a diagram illustrating an example configuration of the job information. In  FIG. 7 , the job information includes a job ID, a user name, user information, print attribute, an applied rule ID, a date, a file path name, a deletion flag, and the like. 
         [0060]    The job ID is identification information allocated to every printing job. For example, the job ID may be given to the printing data by the user PC  30   a . The user name is received with the printing data. The user information is obtained through the successful authentication. The charge code is included in the user information. The print attribute is extracted from the printing data. The applied rule ID is identification information of a print rule which is determined to be applied to the printing data. The date indicates a date when the printing job is generated. The file path name is path name of the file in which the printing data is included and stored in step S 106 . The deletion flag is information indicating whether to automatically delete the job information in response to executing the printing job regarding the printing data, where the flag information indicates “True” or “False”. The deletion flag may be set by the user PC  30  when inputting print instruction, or may be set by the business base server  10   a.    
         [0061]    The job information generation unit  123  stores the generated job information in the job information storage unit  131  (step S 108 ). In the present embodiment, the association of the printing data with the job information is achieved by the file path name included in the job information. However, the printing data may be associated with the job information by other means. 
         [0062]    In the following, a process performed when the printing job regarding the printing data stored in the business base server  10  is executed will be described. 
         [0063]      FIG. 8  is a sequence diagram illustrating an example process performed when the printing job is executed. In  FIG. 8 , the user operates any of the image forming apparatuses  20   a . Also, at start of the process illustrated in  FIG. 8 , a log-in screen is displayed on the operational panel  25  of the image forming apparatus  20   a  to be operated. 
         [0064]    In response to the user inputting user name and password through the log-in screen, the extended authentication application  2222  of the image forming apparatus  20   a  transmits an authentication request including the user name and password to the authentication server  50  (step S 201 ). The authentication unit  51  of the authentication server  50  authenticates the user name and password with reference to the user information storage unit  52 . In a case of successful authentication, the authentication unit  51  transmits a response including user information corresponding to the user name to the extended authentication application  2222  (step S 202 ). 
         [0065]    Upon receiving the response including the user information, the extended authentication application  2222  stores the user information in the RAM  212 . Also, the extended authentication application  2222  sets the successfully authenticated user name in the control service  225  through the SDK platform  223  to be the user name of logged-in user. Consequently, respective application programs operated in the image forming apparatus  20   a  can know the user name of logged-in user by inquiring the user name to the control service  225 . Also, the extended authentication application  2222  erases the log-in screen. When the log-in screen is erased, the user can use the functions (applications) of the image forming apparatus  20   a.    
         [0066]    In response to the user inputting an instruction to use the storage print application  2221 , the storage print application  2221  transmits a request of job list including the user name of logged-in user to the business base server  10   a  (step S 203 ). Additionally, for example, the storage print application  2221  acquires the user name of logged-in user set in the control service  225  through the SDK platform  223 . Also, in respective image forming apparatuses  20   a , an IP address of the business base server  10   a  is set in advance. 
         [0067]    Upon the job information management unit  124  of the business base server  10   a  receiving the request, the job information management unit  124  acquires the job information items including the user name from the job information storage unit  131 , where the user name is included in the request. Then, the job information management unit  124  transmits the job list consisting of the acquired job information items to the storage print application  2221  (step S 204 ). The storage print application  2221  displays a job selection screen including the job list on the operational panel  25 . 
         [0068]    In response to the user selecting any of the job information items in the job selection screen, the storage print application  2221  transmits an acquisition request of printing data including a job ID (hereinafter referred to as “object job ID”) of the selected job information to the business base server  10   a  (step S 205 ). 
         [0069]    Upon receiving the acquisition request, the data management unit  125  of the business base server  10   a  generates a session ID for the printing data to be acquired based on the acquisition request (step S 206 ). That is, the session ID is identification information generated with respect to every printing job regarding the printing data, uniqueness of the session ID is ensured within one business base server  10 . Therefore, another session ID is generated when an acquisition request of printing data is received from another image forming apparatus  20   a  in the business base A. 
         [0070]    Then, the data management unit  125  transmits an acquisition request of authentication code, which includes the user name, the charge code, and the generated session ID, to the extended authentication application  2222  of the image forming apparatus  20   a  that is the request source of the acquisition request of printing data (step S 207 ). Here, the user name and the charge code included in the acquisition request are acquired from the job information (hereinafter referred to as “object job information”) of the object job ID received in step S 205 . Also, the user name and the charge code may be transmitted from the storage print application  2221  in step S 205 . In this case, the storage print application  2221  may inquire the charge code to the extended authentication application  2222 . 
         [0071]    Upon receiving the acquisition request of authentication code, the extended authentication application  2222  generates the authentication code, and stores the generated authentication code associated with the session ID received with the acquisition request in e.g., RAM  212  (step S 208 ). Then, the extended authentication application  2222  transmits the generated authentication code to the data management unit  125  that has transmitted the acquisition request of the authentication code (step S 209 ). Additionally, the authentication code is identification information generated on a printing job-by-printing job basis, and is used for determining validity of the printing data. A method for generating the authentication code is not limited. For example, the authentication code may be generated using at least any one of the user name, the charge code, and the session ID included in the acquisition request of the authentication code. Also, the extended authentication application  2222  may generate the authentication code in the only event that the user name and the charge code included in the acquisition request are the same as those of the logged-in user of the image forming apparatus  20   a  stored in the RAM  212 . 
         [0072]    Upon receiving the authentication code, the data management unit  125  of the business base server  10   a  associates the session ID generated in step S 206  with the object job information stored in the job information storage unit  131  (step S 210 ). For example, a session ID may be added to the object job information. 
         [0073]    Then, the data management unit  125  acquires the printing data (hereinafter referred to as object data) identified by the file path name included in the object job information from the data storage unit  132 , and gives the authentication code received in step S 209  to the object data (step S 211 ). For example, the authentication code is embedded in the object data. The object data in which the authentication code is embedded and the session ID generated in step S 206  are transmitted to the storage print application  2221  that has transmitted the acquisition request of the printing data (step S 212 ). 
         [0074]    Upon receiving the object data and the session ID, the storage print application  2221 , for example, transmits the object data to a predetermined port opened by the print application  2212  through socket communication in the image forming apparatus  20   a  (step S 213 ). Additionally, the predetermined port also becomes a destination when the user PC  30  directly transmits the printing data to the image forming apparatus  20   a . That is, the print application  2212  included in the standard application package  221  does not expect that the storage print application  2221  included in the SDK application package  222  is provided. Therefore, the storage print application  2221  inputs the printing data to the print application  2212  by using an interface (that is, a port for receiving printing data from the user PC  30 ) already included in the print application  2212 . Additionally, by embedding the authentication code in the printing data, the authentication code can be input with the printing data to the print application  2212  through the port. 
         [0075]    Upon receiving the printing data, the print application  2212  extracts the authentication code from the printing data, thereby requesting the extended authentication application  2222  to authenticate the authentication code (step S 214 ). Additionally, the print application  2212  does not expect the extended authentication application  2222  included in the SDK application package  222  either. However, authentication function of the control service  225  is expected to be extended in advance because the authentication is one of basic functions while the authentication is likely to be performed in different manner in accordance with customers who use the image forming apparatus  20 . Specifically, although a normal authentication function is provided by the control service  225 , an application program having an extended authentication function (in this case, extended authentication application  2222 ) transmits, at starting the application program (normally same as start timing of the image forming apparatus  20 ), a notification to the control service  225 , where the notification is to declare that the application program performs the authentication instead. To be exact, the notification from the extended authentication application  2222  included in the SDK application package  222  is transmitted via the SDK platform  223 . Upon receiving the notification from the SDK platform  223 , the control service  225  recognizes that the authentication function is provided by the SDK platform  223 . Therefore, in a case where the control service  225  accepts a request related to the authentication after the reception of the notification, the control service  225  forwards the request to the SDK plat form  223 . Further, the SDK platform  223  forwards the request to the application program (in this case, extended authentication application  2222 ) included in the SDK application package  222  that has transmitted the notification to perform the authentication. Therefore, in view of print application  2212 , the authentication request of the authentication code in step S 214  is transmitted to the storage print application  2221  by calling an API of the control service  225 . Additionally, the authentication process performed in step S 201  is also performed by the extended authentication application  2222  in this way. That is, the authentication request of the user name and password input in the log-in screen is transmitted to the extended authentication application  2222  via the control service  225  and the SDK platform  223 . 
         [0076]    Upon receiving the authentication request of the authentication code, the extended authentication application  2222  authenticates the authentication code by determining whether the authentication code included in the authentication request is the same as the authentication code stored in step S 208 . That is, in a case where the authentication code included in the authentication request is the same as the authentication code associated with the session ID and stored in step S 208 , the authentication is performed successfully. The authentication result is reverted to the print application  2212  via a reversed path of the authentication request (step S 215 ). In a case where the authentication result indicating authentication failure is received, the print application  2212  refuses execution of the printing job. In this case, processes after step S 217  are not performed. In contrast, in a case where the authentication result indicating successful authentication is received, the print application  2212  starts executing the printing job regarding the printing data (step S 216 ), and transmits a response indicating complete reception of the printing data to the transmission source (storage print application  2221 ) of the printing data transmitted in step S 213  (step S 217 ). 
         [0077]    Upon receiving the response indicating complete reception of the printing data, the storage print application  2221  transmits information indicating successful transmission of the printing data to the print application  2212  and the session ID received in step S 212  to the log management unit  126  of the business base server  10   a  (step S 221 ). Additionally, in a case where the response indicating complete reception of the printing data is not received due to time-out, the storage print application  2221  transmits information indicating transmission failure of the printing data and the session ID to the log management unit  126 . 
         [0078]    Upon receiving the information indicating successful transmission or transmission failure of the printing data (hereinafter referred to as “transmission result”), the log management unit  126  of the business base server  10   a  acquires the object job information associated with the session ID that has been received with the transmission result from the job information storage unit  131  (step S 222 ). Then, the log management unit  126  transmits the acquired object job information, the transmission result received in step S 221 , and the session ID to the management server  40  (step S 223 ). 
         [0079]    The log unification unit  41  of the management server  40  stores the object job information, the transmission result, and the session ID in the unified log storage unit  42 , which are associated with each other. Additionally, the session ID may be duplicated because the session ID is generated on a business base server  10 -by-business base server  10  basis. Therefore, in the unified log storage unit  42 , identification information of the business base server  10   a  that is a transmission source of the object job information, etc., may be stored associated with the object job information, the transmission result, and the session ID. Alternatively, uniqueness of the session ID may be achieved by forming the session ID in a manner such that the identification information of respective business base servers  10  is included as a part of the session ID. In the following, a case where the session ID is formed in the above described manner will be described. 
         [0080]    In a case where the deletion flag is “True”, the job information management unit  124  of the business base server  10   a  deletes the object job information from the job information storage unit  131 , and deletes the printing data corresponding to the object job information from the data storage unit  132  (step S 224 ). 
         [0081]    Then, the print application  2212  reports the authentication code of the printing job and information (hereinafter referred to as “job result information”), indicating the execution result of the printing job, to the extended authentication application  2222  (step S 231 ) upon execution of the printing job controlled by the print application  2212  being successfully performed or being terminated due to abnormality in the image forming apparatus  20   a . The authentication code of the printing job means the authentication code authenticated in step S 214  and S 215 . Additionally, for example, similar to the authentication request in step S 214 , the authentication code and the job result information are also reported to the extended authentication application  2222  via the control service  225  and the SDK platform  223 . 
         [0082]    The extended authentication application  2222  transmits the session ID stored and associated with the reported authentication code and the reported job result information to the log unification unit  41  of the management server  40  (step S 232 ). The log unification unit  41  stores, in the unified log storage unit  42 , the received job result information associated with the object job information that is stored in the unified log storage unit  42  and associated with the received session ID (step S 233 ). 
         [0083]    Additionally, the job information and the job result information may be unified by the business base server  10   a . In this case, the log management unit  126  of the business base server  10   a  does not perform the process of step S 223 . Also, the object job information is not deleted in (at timing of) step S 224 . Further, the extended authentication application  2222  transmits the session ID and the job result information to the log management unit  126  of the business base server  10   a  in step S 232 . The log management unit  126  unifies the object job information stored in the job information storage unit  131  and associated with the session ID and the received job result information, and thereby transmits the unified result to the log unification unit  41  of the management server  40 . Then, the object job information is deleted from the job information storage unit  131 , and the printing data corresponding to the object job information is deleted from the data storage unit  132  in a case where the deletion flag of the object job information is “True”. 
         [0084]    Also, functions of the management server  40  may be provided by the business base server  10   a . That is, log information may be managed on a business base-by-business base basis. 
         [0085]    As described above, according to the present embodiment, an identical session ID is assigned to the information regarding the printing data managed in the business base server  10  and to the information regarding execution of the printing data in the image forming apparatus  20 . Consequently, the respective information can be associated based on the session ID. 
         [0086]    Additionally, in the present embodiment, although the printing data is described as example data to be processed and output by an apparatus, other types of data and other types of apparatuses may be used in an embodiment as long as the data can be stored in a storage device and retrieved from the storage device by the apparatus. For example, an embodiment may be applied to a projector and image data projected by the projector. 
         [0087]    Additionally, the image forming apparatus  20  is an example data processing apparatus in the present embodiment. The business base server  10 , the management server  40 , the business base server, and the management server are respectively an example of information processing apparatus. The data management unit  125  is an example first generation unit, first storage processing unit, first reception unit, and first transmission unit. The log management unit  126  or the log unification unit  41  is an example of second storage processing unit. The session ID is example first identification information. The authentication code is an example of second identification information. 
         [0088]    The extended print application is an example of second reception unit. The extended authentication application  2222  is an example of second generation unit and second transmission unit. The print application  2212  is an example of execution unit. 
         [0089]    Herein above, although the present disclosure has been described with respect to a specific embodiment for a complete and clear disclosure, the appended claims are not to be thus limited but are to be construed as embodying all modifications and alternative constructions that may occur to one skilled in the art that fairly fall within the basic teaching herein set forth.
