Abstract: A printing gap adjustment mechanism compensates for the change in the pring gap variation caused by the relative motion between two side walls of the printer frame supporting a platen and two guide rods slidably supporting a print head. The mechanism includes a compensator rod and a pair of eccentric members rotatably mounted in a compensator plate which is pivotally mounted on one side wall of the printer frame. One end of the compensator rod is frictionally secured to the opposite side wall while the other end is rotatably supported in an opening in the other side wall and is secured to an eccentric mounted to the compensator plate. One of the guide rods supporting the print head is located near the platen and is secured between two eccentric members, one of which is rotatably mounted in the compensator plate and the other is rotatably mounted in the opposite side wall. The other guide rod is secured between the two side walls.
