Apparatus for reading and printing on a recording medium

摘要

Unitary apparatus for reading and/or printing a recording medium incorporates a read unit for optically scanning the recording medium and a print unit in the form of an ink jet printer for printing on the same or a subsequent area of recording medium. The recording medium is conducted in a planar condition through a path overlying the read unit and the print unit, both of which are mounted in fixed relation on a printer carriage for transverse movement relative to the printing medium. In this way line-by-line scanning of the recording medium or line-by-line printing of the recording medium can occur simultaneously with paper transport. The scanning and printing units may be either single color units, or may be multicolor scanning and multicolor printing units.
