ABSTRACT:
A dot-matrix impact printer, including a print head including a piezoelectric element, and a print wire which is movable from a non-operated position thereof to an operated position thereof, owing to displacement of the piezoelectric element, to produce an imprint on a surface of a recording medium. The printer uses a piezoelectric control device which is responsive to a wire activation command, for applying a controlled drive voltage to the piezoelectric element to thereby activate the print wire to the operated position, wherein the drive voltage includes a static voltage which decreases with increasing paper thickness and which gets the wire close to the paper, and a dynamic voltage which provides the print force and increases with increasing paper thickness.
