Abstract: The check writer, for imprinting checks or negotiable instruments is comprised of a frame having a printing line, a plurality of type segment members supported by the frame with each segment member having a set of centered printing characters on the segment member facing. The segment members are movable to locate the desired printing characters on the printing line and cooperate with a prefix holder assembly supported by the frame and structurally arranged to receive and position a sliding prefix plate adjacent to the printing characters on the printing line. The width and length dimensions of each printing face on each type segment is substantially identical which assists in the cooperation between the exposed printing characters and the imprinted check to prevent criminal alteration.
