  • Publication number: 20050240971
    Abstract: Internet-based printing to a home printer in which the print job is pre-rasterized at the cable head end and sent in rasterized format to the set top box. Because the print job is pre-rasterized at the cable head end, and not at the set top box, resources are not wasted at the set top box when they are more readily available at the cable head end. In addition, because of the high speed communication network already in existence between the cable head end and the set top box, even large pre-rasterized print jobs can be transmitted to the set top box in reasonable amounts of time, meaning more quickly than a situation in which it was the set top box that performed rasterization.

  • Publication number: 20050216748
    Abstract: A method and system for notifying an administrator when a user of a document processing device, such as a multifunction peripheral device, requests a change in the configuration of the document processing device. A user accesses the document processing device via a user interface, requesting that the configuration of the device be altered. The user then provides identification information verifying the identity of the user. An authentication server then determines whether or not the identified user is authorized to make the change in the device configuration. Access is denied to unverified or unauthorized users attempting to change the configuration of the document processing device. In the event that the user is verified, but not authorized to make the requested change, the authentication server rejects the requested change and notifies the administrator of the attempt to change the configuration.
