摘要： A method of compressing pixel information is described. The pixel data is received in a data stream and compressed into a compressed data format by identifying a run of consecutive bytes of the data stream based on the similarity of the consecutive data bytes in the data stream. A mode bit of a compression byte is used to indicate whether a run of consecutive bytes is identified. Count bits of the compression byte are used to indicate the number of times the data bytes are repeated and zero counts may be used to indicate particular types of runs, for example, runs to the end of a scan line and the end of an object. Where a pixel byte is represented by 8 bits, the data stream may be compressed in multiples of four bytes at a time. If a pixel is represent by less than 8 bits, the compression method may look for repetitions of similar bytes one byte at a time.

摘要： Disclosed is a method, system, and program for error checking raster objects including pixel information for a print job. A plurality of raster objects form the print job. A raster object is received including sequence information indicating an ordering of the raster object with respect to other raster objects in the print job. A determination is made from the sequence information as to whether the raster object is received in a correct order with respect to other raster objects in the print job. This ensures that the pixel information for the raster object is intended for a current pixel line being processed. An indication of error status is made if the sequence information indicates that the raster object was not received in the correct order with respect to the other raster objects in the print job.

摘要： A method and system for decompressing image data in a digital scanning system such as a printer. A plurality of streams of digital data are received in a compressed format. The compressed format contains a control byte preceding a plurality of data bytes. A initial RLE mode bit of the control byte indicates whether the following data bytes are run length encoded or not run length encoded and subsequent bits indicate a repeat amount. If the following data bytes are run length encoded, the decompression apparatus determines the number of times the data byte(s) are to be repeated at the output of the apparatus. In special cases where the repeat count is a zero, the mode bit may indicate that the data byte is to be repeated either to an end of scan marker or to an end of object marker. The RLE mode bit may also indicate that non-run length encoded data is to be passed through as-is, preferably in multiples of a selected integer number. The input data stream may be buffered and received with the use of a barrel shifter register having a plurality of slots. Control logic determines which slots are empty and fills one slot at a time. The run-length encoded and non-run length encoded data are combined at an output stage. A plurality of decompressed circuits may be present and may decode separate data streams in parallel for continuous submission to a print engine.

摘要： A method and system are disclosed for the modification of the timing of one of a plurality of PEL clocks included within an electrophotographic device. A first indicator is generated which is associated with a first position on a print receiving material. A second indicator is generated which is associated with a second position on the print receiving material. A first enable signal is generated for initiating a first scan. The first scan is executed utilizing a first laser beam synchronized by a first PEL clock. A second enable signal is generated for initiating a second scan. The second scan is executed utilizing a second laser beam synchronized by a second PEL clock. The first and second scans are executed approximately concurrently. An offset of the second position from the first position is determined. The timing of a second PEL clock is modified by adjusting the second enable signal utilizing the offset so that the first and second positions are approximately aligned.

摘要： A printer system includes a printer engine that produces an engine power status signal and a printer controller that produces a controller power status signal. A power management interface receives the engine power status signal and the controller power status signal and alters the power status of the printer controller by generating a power management signal based on the power status of the printer controller and the printer engine. The interface preferably alters the power status of the printer controller such that the power status of the printer controller tracks the power status of the engine. The interface may assert the power management signal in response to a transition in the engine power status signal and may format the power management signal according to an industry stand such as the PCI defined PME signal. The interface may be implemented as a board inserted in a PCI connector of the printer controller.
