Description

  The present invention relates to an information processing system and an information processing method for performing printing by applying a printing policy for each user in an environment in which management servers are distributed at a headquarters site and a branch site.

  2. Description of the Related Art Today, a server on a network and a client PC (Personal Computer) are linked to achieve a required purpose.

  For example, in the technique disclosed in Patent Literature 1, when data is transmitted by a client terminal, the management server receives status data of the client terminal via a data relay device that relays communication data in a network. The management server permits the relay of the data transmitted from the client terminal only when the status of the client terminal has reached the standard. Therefore, data communication can be performed while confirming that the status of the client terminal, such as virus countermeasures and security management, has reached the standard.

  Also, for example, in the technique of Patent Document 2, authorization information (information on which function of the image forming apparatus is permitted to be used) is stored in the server, and the server stores the authorization information after logging in from the image forming apparatus or the PC. Acquire the authorization information to perform, and generate and execute a job within the permitted range based on the acquired authorization information. For example, when a user who is not permitted to perform color printing performs printing, any image forming apparatus on the network can perform only monochrome printing. As described above, a printing policy can be applied to each image forming apparatus on a network for each user.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[overall structure]
First, the overall configuration of an information processing system 1 according to an embodiment of the present invention will be described. FIG. 1 is an overall configuration diagram of an information processing system 1 according to an embodiment of the present invention.

  As shown in the figure, the information processing system 1 includes a master server 10 installed at a headquarters site, site servers 30A to 30C, image forming apparatuses 20A to 20C, and PCs 40A installed at sites of branches A to C, respectively. 40C. These devices are connected to a network.

  In the following, when it is not necessary to distinguish the devices of each branch, they are referred to as a site server 30, an image forming apparatus 20, and a PC 40.

  The master server 10 controls the site servers 30A to 30C of each branch site.

  For example, at the site of the branch C, the user generates a print job in cooperation with the site server 30C using the PC 40C, and the generated print job is sent to the site server 30C, spooled, and printed by the image forming apparatus 20C. You. The same applies to branches A and B.

  Different segments are allocated to the LAN (Local Area Network) of each site.

  For example, the IP address of the master server of the headquarters site is 10.10.10.1, and the IP address of the site server of the site of the branch C is 10.10.1.1.1.

  The IP address of the PC 40A in the branch A is 10.10.13.110. However, when the user travels to the site of the branch C with the PC 40A and connects to the network, the DHCP (Dynamic Host Configuration Protocol) A new IP address 10.10.11.102 or the like is allocated to the PC 40A.

  The overall configuration of the information processing system 1 according to the embodiment of the present invention has been described above.

[Conventional general processing flow]
Next, for comparison, an outline of a general processing flow performed conventionally is described. FIG. 2 is a diagram for schematically explaining a general flow of a conventional process.

  At the site of the branch C ', the PC 40C' includes a printer driver 41a 'and a transmission destination switching unit 41b'. The IP address of the site server 30C 'is set in the printer driver 41a' and the transmission destination switching unit 41b '.

When generating a print job, the following steps are performed:
(1) First, the printer driver 41a 'requests the site server 30C' for user authentication.
(2) If the authentication is successful, the site server 30C 'provides the authorization information.
(3) The printer driver 41a 'generates a print job based on the provided authorization information and sends it to the destination switching unit 41b'.
(4) The transmission destination switching unit 41b 'transmits the received print job for spooling in the site server 30C'.
(5) The site server 30C 'sends the spooled print job to the image forming apparatus 20C.
(6) Printing is performed by the image forming apparatus 20C.

  As described above, conventionally, the IP address of the site server 30C 'to be the communication partner must be set in the printer driver 41a' and the transmission destination switching unit 41b ', which is troublesome.

  Further, even if a deployment tool is used for setting the IP address, since the IP address of the site server is different for each site, it is necessary to prepare a property file for setting the number of sites, which is troublesome.

  As described above, for the sake of comparison, a general flow of a conventional process has been described.

[Processing flow in the present embodiment]
Next, an outline of a processing flow in the present embodiment will be described using the branch site C as an example. FIG. 3 is a diagram for explaining the outline of the processing flow in this embodiment, taking the branch site C as an example.

  In the present embodiment, the PC 40C has the IP address of the master server 10 set only in the printer driver 41a.

When generating a print job, the following steps are performed:
(1) First, the printer driver 41a of the PC 40 inquires of the master server 10 about the IP address of the site server that is to cooperate with the master server 10. This inquiry is performed with the IP address of the PC 40 (for example, 10.10.1.101).
(2) Next, the master server 10 at the headquarters site refers to its own IP address mapping table 17a (described later) and returns the IP address of the site server with which the PC 40 cooperates.
(3) Next, the printer driver 41a, which has obtained the IP address of the site server 30C to be linked, requests the site server 30C for user authentication.
(4) If the authentication is successful, the site server 30C provides the authorization information.
(5) The printer driver 41a generates a print job based on the provided authorization information, embeds the IP address of the site server in the job data, and sends the job data to the transmission destination switching unit 41b.
(6) After extracting the address of the site server 30C from the received print job, the transmission destination switching unit 41b transmits the job data for spooling in the site server 30C.
(7) The site server 30C sends the spooled print job to the image forming apparatus 20C.
(8) Printing is performed by the image forming apparatus 20C.

  As described above, in the present embodiment, it is only necessary to set the IP address of the master server 10 only for the printer driver for all the PCs in the information processing system 1, so that the time and effort for the setting can be greatly reduced. Can be done.

  In the above description, information on the address of the site server is embedded between the printer driver 41a and the transmission destination switching unit 41b and transferred.

  This is because, for example, when the OS (Operating System) is Windows (registered trademark), direct inter-process communication between the printer driver 41a and the destination switching unit 41b (port monitor) is prohibited.

  As described above, when the PC at each branch site inquires the address of the site server to be linked together with its own IP address, the master server 10 changes the range of the IP address of the PC on the right side of the IP address mapping table 17a. Search and return the site server IP address of the corresponding entry.
