ABSTRACT:
A printer carriage is carried by the guide bars of a printing unit with the help of busings and is moved along the guide bars by means of a traction mechanism. The traction mechanism is attached to the printer carriage and/or the bearing elements, in such a way that a compensating torque is exerted on the printer carriage or the bearing elements. The compensating torque counterbalances the torque generated during reversal of movement so that the carriage does not rock when it reaches an endpoint of its travel.
