  • Patent number: 7916733
    Abstract: An information processing apparatus functioning as a data communication apparatus determines whether data communication with another information processing apparatus in the same local network is carried out using a global network address. If it is determined that the data communication is carried out using a global network address, the information processing device carries out control so that the data communication is carried out using a local network address.

  • Patent number: 7899013
    Abstract: A system for connecting an output device to an external device via a network is disclosed. The output device includes a radio communication section, a selecting section, and a requesting section. The radio communication section communicates by radio. The selecting section selects the external device as an alternative device for alternatively communicating data by radio with another radio communication device when receiving an output request from a radio communication device. The requesting section requests alternative reception of the output request to the selected external device. The external device includes control section for performing a process which transfers the output request obtained by the radio communication with the other radio communication device to the output device via the network in accordance with the alternative request from the output device.

  • Publication number: 20100293411
    Abstract: An image forming apparatus that can be used even when an access error occurs due to replacement of component elements. When replacement of a component element of the image forming apparatus is detected, it is determined whether or not a predetermined process has been normally carried out on the component element. When it is determined that the predetermined process has not been normally carried out, another process different from the predetermined process is carried out. When the other process has been normally carried out, the predetermined process for the component element is changed to the other process.

  • Publication number: 20090244590
    Abstract: An image forming apparatus detects whether a sub board, which performs image processing, is in a processing-disabled state. If it is detected that the sub board is in the processing-disabled state, the image forming apparatus activates a virtual environment on a main board, which performs information processing, to allow an image processing unit configured to perform the image processing to run on the virtual environment. The image forming apparatus transfers data processed by the image processing unit to the sub board when the sub board comes into a processing-enabled state and then prints and outputs the data via a print engine.

  • Publication number: 20070268518
    Abstract: The present invention provides, to an image forming apparatus that cannot interpret access control information representing permission to execute printing, a mechanism for flexibly restricting a print job by using the access control information. Specifically, a proxy server verifies whether the access control information is valid. If the proxy server verifies that the access control information is valid, an ACT in the print job is deleted. The print job with the ACT deleted is queued. The queued print job is transmitted and printed out in the image forming apparatus.

  • Patent number: 7080166
    Abstract: A communication apparatus has a communication unit that transmits data to a designated destination, and a management unit that manages ID information determined for each user and address location information associated with the ID information, wherein the address location information indicates a location that stores address information for designating the destination to transmit the data by said communication unit. The user inputs the ID information via an input unit, and an obtaining unit specifies the address location information managed by said management unit based on the input ID information, communicate with an external apparatus via a network based on the address location information, and obtains the address information residing at the external apparatus corresponding to the location specified by the address location information. The communication unit transmits the data to the destination designated from the address information obtained by said obtaining unit.

  • Patent number: 7006836
    Abstract: A specific device periodically detects devices existing proximally thereto, and holds a list of information of services provided by the detected devices. Further, as its own device information, the specific device publicizes that the device holds the list of service information relating to the proximate other devices. When the other device is to use a specific service, the device holding the service information list is distinguished, a list of devices among the detected devices which provide the desired service is obtained, and by connecting the other device to a device that is on the list and is within a communication range of the other device, a connection can be made quickly to the device providing the desired service.

  • Publication number: 20060028677
    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.

  • Publication number: 20060028678
    Abstract: When data of a print job are stored on another device or a file server, data transfer is required to obtain image data, and the start of a print process and a preview process take time compared to a print job whose data is stored in a local storage device. Hence, a print job is started, and it is checked if data for all pages of the print job are locally held. If data for all pages of the print job are locally held, a print process is continued; otherwise, data for remaining pages are obtained and undergo the print process parallel to the print process for a first part.
