An interface for use with a low cost, low speed non-impact line printer, perhaps a xerographic processing device utilizes the video output stream from a computer or word processor cathode ray tube (CRT) output. The video and sync are separated. The sync signals are used to drive necessary timing signals at start of frame, start of field, end of field, start of line, end of h e , line counting, end of frame, and end of print.
