Abstract
A system for clearing a buffer for holding bitmap data output by a decomposer or interpreter in a digital printing apparatus exploits a decompressor chip. Instead of having the processor directly write blank data into the buffer to clear the buffer, a 'buffer clear' software utility sends compressed blank image data to the decompressor chip, which in turn decompresses the blank image and writes the decompressed blank image to the necessary location in the buffer.
