摘要： The printing speed of a page printer is modified relative to rasterization execution time (RET) for display commands that define images to be printed on each page strip of a page. The printer includes a variable frequency clock for producing a plurality of clock frequencies for modifying the printing speed. A processor compares the RET for each page strip with a threshold value. When a complex page strip is found whose RET exceeds the threshold, the variable frequency clock is appropriately controlled to generate a lower frequency clock signal to the print engine. The lower frequency signal causes the print engine to operate at a modified (slower) rate for a sufficient amount of time on any previously queued page strip(s) to provide an extended time frame for allowing the complex page strip to be rasterized. Printing speed is slowed, but rasterization time (clock speed) for the complex page strip is not slowed. Accordingly, display commands in the complex page strip are rasterized within the extended amount of time provided by the reduced print speed, thereby preventing a print overrun.

摘要： The software on the host machine examines a pixel, either alone or in relation to adjacent pixels. Based on the image data contained in the pixel or group of pixels, a multi-bit value is generated that can be used by the printing device to easily reproduce the necessary detail of the original pixel. The multi-bit value also contains print engine control parameters to handle items such as toner miser mode, toner explosion, edge roll off, etc. The multi-bit value can be generated algorithmically by using a lookup table or by some combination of these methods.

摘要： A method for image processing loads a cache line width column of image data into a data cache. The cache line width column of image data is then processed to enhance the image data; and the enhanced image data is then outputted.
