  • Patent number: 8139243
    Abstract: A print job often includes secret information, and information may suffer sniffing from devices that execute distributed processing of jobs, or on the network. Therefore, executing the distributed processing of a print job including secret information reduces the robustness in terms of security protection. Hence, upon reception of a job, a task manager (TM) issues, to a dynamic job scheduler (DJS), a request of target devices of distributed processing according to a security level indicating the importance level of data included in that job. The DJS notifies the TM of the target devices, and the TM transmits divided jobs to the target devices.

  • Patent number: 7757937
    Abstract: A license of an optional feature used in a transmission source apparatus can be properly transferred to a transmission destination apparatus. A first apparatus outputs a first license transmission code based on an identifier of designated application software and an identifier of the first apparatus. On receiving the first license transmission code, a second apparatus outputs a second license transmission code based on the first license transmission code, an identifier of the second apparatus, and a unique identifier. On receiving the second license transmission code, the first apparatus outputs a third license transmission code based on the second license transmission code and designated transfer details, and updates license information in the first apparatus in accordance with the designated transfer details. On receiving the third license transmission code, the second apparatus updates license information in the second apparatus based on the third license transmission code.

  • Patent number: 7664321
    Abstract: This invention provides the following environment. That is, an original document file corresponding to a document to be copied is specified from image data of that document to be copied, and a print process is made based on the specified file so as to prevent deterioration of image quality. Also, when a document to be copied is not registered, a registration process is executed to suppress deterioration of image quality in an early stage. Furthermore, since the document is converted into vector data, re-use of such document is facilitated, and deterioration of image quality can be suppressed even when an image process such as enlargement or the like is made. To this end, when an original digital file cannot be specified, an apparatus of this embodiment executes a vectorization process (S54), converts the obtained vector data into a data format that can be re-used by an application (S55), and registers the converted file in a file server (S56).
