    摘要: Systems in accordance with the presently claimed invention use input data to create an output pulse that is a fraction of the width of an input pulse. In some embodiments, the invention accepts input data and an input signal that has pulses of a specific frequency. In some embodiments, the invention uses a phase lock loop to create multiple signals of a higher frequency than the frequency of the input signal. Each of these multiple signals is offset by a certain phase from the other signals. In some embodiments, the invention synchronizes the input data to each of these multiple signals. The invention uses the phase difference between the multiple signals to create an output pulse as a function of the input data that is a fraction of the width of the input pulse.

    摘要: Systems and methods are provided for reducing data size of at least one bitmap image, wherein the bitmap image comprises a plurality of color blocks, wherein each color block is associated with a distinct color plane. In some embodiments, the bitmap image may be compressed. At least one compressed color block that is contained in a transfer frame may be determined, based on information pertaining to a physical offset between successive color planes when they are rendered on a print medium. Further, at least one compressed color block in the transfer frame may be tagged, if the size of the transfer frame exceeds a threshold, and the resolution of the at least one compressed color block that is tagged may be reduced.

    摘要: Systems and methods are provided for transferring image data to a printing device over a network connection. The image data comprises at least one image block associated with a first print page, wherein the image block comprises a plurality of color blocks, each color block being associated with a distinct color plane. In some embodiments, a transition delay may be computed for the transfer of a second print page immediately succeeding the first page. The transition delay is computed based on a function of a physical offset between successive color planes in relation to an order in which the color planes are processed on the printing device and the volume of data in the image block. Further, scheduled transfers of image data associated with the second print page may be delayed by the computed transition delay.

    摘要: An apparatus and method for processing pixel data is presented that includes a plurality of image forming modules coupled to a data control module. The data control module includes a plurality of memory units. Each memory unit can store a portion of an image. The data control module receives a first signal and a second signal and selects at least one of the plurality of image forming modules to send the image portions stored in the plurality of memory units based on a timing relationship between a first image alignment event on the first signal and a second image alignment event on the second signal.
