Abstract
Apparatus for processing and displaying binary pixel image data includes a printer for receiving image data and for presenting the image data as bilevel pixel values. The printer includes a processor for altering the received image data into an output image. A host processor stores multi-bit-per-pixel image data and further includes image processing software and data transmission circuitry coupled to the printer. The host processor compares the bilevel pixel data size and the multi-bit-per-pixel data size and, based upon a size relationship determined from the comparison, processes the multi-bit-per-pixel image data into bilevel pixel values in either the printer or the host processor so as to transmit the least amount of image data between the host processor and the bilevel printer.
