Abstract (en)

[origin: US4603984A] A bidirectional dot-matrix printer compensates for dislocations of the location of the last print clock with printed information on a printed line by producing at least one further print clock after the end of the printing information, and initiating breaking of the printer carriage after such dummy print clocks. During movement of the print head in the reverse direction on the subsequent line, the dummy print clocks are taken into consideration before initiating print clocks which are coincident with printed information.
