ABSTRACT:
Dot-matrix printer for printing on a paper resting against a platen includes a bendable piezoelectric lamina, means for fixedly supporting the bendable piezoelectric lamina along a first edge, a planar rerromagnetic member, means for operatively connecting the planar ferromagnetic member to the bendable piezoelectric lamina at a region remote from the first edge, a dot print element, means for mounting the dot element to be responsive to the movement of the bendable piezoelectric lamina in the region of the planar ferromagnetic member to extend along a line parallel to the plane of the planar ferromagnetic member, control means for generating first or second voltage signals for energizing the bendable piezoelectric lamina to cause the planar ferromagnetic member to assume a first or a second position, and electromagnetic means for applying a magnetic force on the planar ferromagnetic member such that only when the planar ferromagnetic member is not in the first position is there sufficient force exerted by the dot print element to print on the record medium.
