ABSTRACT:
Color control means for selectively positioning one color of a two-color ribbon between a document-supporting platen and a print head having means for selectively impacting the desired ribbon portion against the document, said color control means comprising a color-select solenoid energized by logic circuitry responsive to a print-color signal. The solenoid is energized to a first position to enable characters of a first color to be printed at selected positions along a line. The logic circuitry includes means for selectively deleting the line feed, and delaying the print enable and print head movement signals during a time interval sufficient to allow for the color select solenoid to move the ribbon to the opposite color position at which time the characters of the opposite color are printed. A modification of the logic circuitry enables a dot-matrix impact printer capable of printing in both the forward and reverse directions to print a single line of intermixed characters of first and second colors in a somewhat similar fashion.
