ABSTRACT:
A single spring presses a moving printhead against a pivotable platen while simultaneously engaging a sliding carrier upon two parallel cross slides. The printhead is mounted on an arm hinged to the carrier. The axis of the hinge is parallel to the line of motion of the carrier along the cross slides. The spring pushes the arm away from the carrier and produces a moment about the hinge which keeps the carrier engaged with the cross slides. The platen pivots to remain completely parallel to the surface of the printhead as the carrier moves along the cross slides.
