Abstract
A printer apparatus includes a marking engine subsystem that records information on an image recording member. An image storage subsystem buffers image data for output to the marking engine subsystem. The image storage subsystem includes an input for receiving rasterized image data. A data compressor operates on the rasterized image data to compress the rasterized image data to form compressed image data. A disk storage module receives, stores and outputs the compressed image data to a semiconductor RAM memory device that stores at least one page of the compressed data. A data decompressor operates on the compressed data output by the RAM memory device and decompresses the compressed data to rasterized data for output to the marking engine subsystem. A RAM controller controls the RAM memory device for outputting the compressed data from the RAM memory device to the decompressor. The disk storage module outputs compressed data to the RAM memory device at a data rate greater than the maximum sustainable data recording rate of the marking engine subsystem.
