Wire-dot impact printer having means for detecting displacement of individual print wires
 A wire-dot impact printer includes a wire-dot print head having a plurality of print wires disposed therein. Each of the plurality of print wires has a distal end, and each is displaced in response to a drive signal so as to strike a printing medium with the distal end. A displacement detecting device is provided for detecting a displacement resulting from the drive signal of each of the plurality of print wires and for outputting a corresponding displacement detection signal. A control unit, which controls the overall printing operation of the impact printer, varies the print repetitive cycle of each of the plurality of print wires in accordance with the displacement detection signal outputted by the displacement detecting unit.
