  • Patent number: 7970838
    Abstract: A mail relay server decodes a received command electronic message to produce and issue a command to a service manager server which is directed to a device manager server for a target printing device. The device manager server produces and issues instructions to the target printing device. If the command includes a request for the reply, the process of executing the instruction in the target printing device includes the target printing device producing and issuing, the reply to the device manager server. The device manager server collects any multi packet reply and transmits the reply to the service manager server which directs the reply to the mail relay server. The mail relay server encodes the received reply to produce and issue a reply electronic message to the requestor.

  • Publication number: 20110150323
    Abstract: A system categorizes one or more objects based at least in part upon one or more characteristics associated therewith. A first classifier includes a rule set to determine if each of the one or more objects meets or exceeds a quality threshold. A second classifier, orthogonal to the first classifier, includes a rule set to determine if each of the one or more objects meets or exceeds a quality threshold. In one embodiment, the quality threshold associated with the first classifier and the quality threshold associated with the second classifier are less than a predetermined target threshold. The result for each object of the first classifier is compared to the result of the second classifier. The object is categorized if the result of the first classifier and the result of the second classifier match. The object is uncategorized if the result of the first classifier does not match the result of the second classifier.

  • Publication number: 20110149313
    Abstract: What is disclosed is a novel system and method for generating a reference color difference quantity guide for spot color print applications. RCDQ values are determined for spot colors obtained from a library of spot colors. A reference color difference quantity guide is created from the spot colors and their respective RCDQ values in a manner more fully disclosed herein. Thereafter, when a user desires to render a job in a particular spot color, the associated RCDQ value for that spot color can be obtained from the reference color difference quantity guide. In various embodiments, recommendations in the form of a suggested printer to use, a media type, a halftone screen, and other meaningful assistance can be provided for selection of spot colors for a given print/copy job that are less sensitive to varying illuminations. The present RCDQ guide provides meaningful extensions in color reproduction in diverse print/copy job environments.
