A system uses GPU accessible, high-speed memory to store compressed or raw video printer data. The system transmits this video data over one or more frames of an HDMI interface and a circuit reconstructs the video data for a page from one or more HDMI frames for communication to a printer.

A proxy software service determines all I/O devices independent of subnet location, on a network; provides a network interface on a wireless subnet that can receive and respond to requests; responds to such requests for each I/O device so identified so that the I/O device is available to the wireless device user for device selection; transfers and translates, if necessary, the IPP stream received from the wireless device to the network address of the I/O device so that the I/O device simulates a compliant I/O device; and transfers and translates, if necessary, all necessary status and command messages from the present protocol to the protocol supported by a legacy I/O device.

Protocol for interaction between wireless devices and other devices

Methods and apparatus for processing a page description language ('PDL') data stream are provided. The methods and apparatus divide the PDL data stream to provide a plurality of PDL segments, create associated first and second data files for each of the PDL segments, and assign the first data file or the second data file associated with each of the PDL segments to at least one of a plurality of PDL processors.

Techniques are provided that allow the user to view on his or her mobile device the body of an email or other items from a message service as well as each of the attachments as thumbnails or individual images. As well, techniques allow the user to view particular attributes of each item, e.g. the number of pages and the page size of a particular attachment. Techniques are provided such that the user may view such thumbnails and/or attributes on a unique URL generated as a result of the generated email. Thus, by such techniques, the user is provided with a platform for mobile devices that allows intuitive selection of what should be or is desired to be printed.

A image is printed from a source of drawing instructions. The image is reducible to pixels arranged in a plurality of ranked image lines. The system employs a storage device having compressed and uncompressed regions. Each region has a designated capacity and each is arranged to store pixels of one or more of the plurality of image lines. A drawing processor is coupled to the storage device and can be coupled to the source of drawing instructions for responding thereto. This drawing processor can store new pixels in the storage device for successively selected ones of the image lines. The drawing processor has a conditional device, a decompression device and an insertion device. The conditional device can compressively encode and move from the uncompressed region to the compressed region, a remote one of the image lines, if: a) the selected one of the image lines is in the compressed region, and b) the uncompressed region has reached its designated capacity. The decompression device can expansively decode the selected one of the image lines, if located in the compressed region. The insertion device can insert one or more new pixels according to the drawing instructions into the selected one of the image lines by storing the selected one in the uncompressed region. The printing system also has a printing engine coupled to the storage device for printing the plurality of image lines in rank order, decompressing compressed ones of the image lines from the compressed region before printing.

Printing system and method

A system and method for performing regression testing on software programs that produce printed output. An original version of a software program resident on a computer is issued known commands to generate a reference display list known to produce a known correct or reference printed page. A bitmap of the reference page is not generated. The reference display list includes image, graphic and text objects described by various attributes. A second modified version of the software program is loaded on the computer and issued the same set of known commands. The second software program generates a second is display list. A display list regression testing software module compares the second display list to the reference display list and identifies any differences by object type and attribute. Hence, incorrect results may be isolated to specific objects and more easily debugged in the source code of the software program. Visual comparison of actual printed output is substantially reduced.
