Abstract: A print service supports print by reference operations. Software hosted or accessible by a web site performs the required functions. A print client may be a print device, for example, that has an Internet connection. A print client might also be a portable wireless device, for example, which then might transfer data transcoded by the print service to a print device. The print service accepts a reference to print content, resolves the reference, obtains the print content, transcodes the print content into a print device ready format, and allows the print client access to the transcoded print data. The print service method realized by such a web site provides commercial potential for web services and content provider partnerships, as a preferred use of the print service might commence with a user of a portable wireless device obtaining a reference to print content while web surfing, communicating that content.

Abstract: A print by reference method for a portable wireless device allows the portable wireless device to obtain a reference that indicates where a print content is located and to wirelessly communicate the reference to a print device causing the print device to use the reference to locate and obtain a desired set of print content and further causing the print device to print the desired print content. Alternatively, the method may cause the portable wireless device to communicate the reference to a print service which responds to the reference by downloading the print content and then forwarding the print content to a print device for printing.

Abstract: A method and system for transmitting data between at least one receiver operatively connected to at least one transmitter, and more particularly to a method and a system for permissible transmission via at least one high-speed link having a plurality of virtual channels. The method includes the receiver sending a virtual channel credit packet for a particular virtual channel to the transmitter, the credit packet being indicative that the receiver is available to receive data and having a unique virtual channel number assigned to said particular virtual channel thereto. The transmitter responds to the virtual channel credit packet, which includes transmitting data to the receiver if data is available. The receiver receives the data transmitted from the transmitter.

Abstract: A method of transferring image data between an initiator device and a target device using a IEEE 1394 standard bus. The present invention combines management functions, command functions, and isochronous data transfer to achieve the transfer of image data. The present invention discovers a target configuration using IEEE 1394 reads of a target configuration read only memory space. As part of the management function, the present invention uses a modified asynchronous data transfer protocol to establish a connection between the initiator and the target. Next, the present invention uses command functions to begin a job to transfer image data over an isochronous channel. Also, the present invention uses asynchronous data transfer to exchange printer job language commands to end a job.
