  • Patent number: 5574831
    Abstract: A printer system which allocates various pages of a job to a plurality of individual printers that each print a different page of the job. The system is therefore capable of increasing the speed of the job without requiring a faster engine speed. The printer system includes a plurality of print engines, a sequenced stacking device, imaging electronics to create raster image signals suitable for the video input of the print engines and control electronics to direct these electrical signals to each of the print engines on a page by page basis and to control the stacking device to direct printed sheets to the output stack in proper sequence. The stacking device loads the print images into a single properly sequenced output stack at a speed of n.times.i images per minute, wherein n is the number of print engines used and i is the speed of a single print engine in images per minute.
