Between the print head, provided with the actuators 1, and the paper 2 there is a relative movement in the direction marked by arrow 3. The print head is additionally provided with at least one standby actuator 4 which, if required, is movable from its waiting position along guide rail 5 to a position 4' at which a defective actuator * is located. By diagnostic means, the printer processor (not shown) continually tests whether all actuators are operating correctly. If a defective actuator is diagnosed, standby actuator 4 is moved to its position.
