ABSTRACT:
A system, method, and processor executable instructions to isochronously communicate in standard USB mode laser printer scan data from a host computer to a laser printer. The host computer transmits a data stream that includes data packets having laser printer scan data, error detection information, and correction packets such as parity packets for use to reconstruct packets having an error. The laser printer receives the data stream, processes the error detection information, data packets and parity packets, and provides a continuous stream of laser printer scan data for printing.
