Abstract
A printer unit for selectively printing on documents fed between a matrix printer and a rotatable inked platen. The platen is actuably movable between a retracted position and an advanced print position. The document while being printed upon is moved at the same speed as the velocity of the periphery of the rotating platen. The document feed is limited by a feed control roller cooperating with a pressure roller. The feed control roller is coaxial with the rotatable platen and is adapted to move therewith between the retracted position and the print position. A solenoid is provided to move the feed control roller and platen between the two positions. The documents are permitted to pass through the print station unimpeded when the roller platen and feed control roller are retracted.
