摘要：Dot-matrix printer for printing on a paper resting against a platen includes a bendable piezoelectric lamina which is supported along a first edge planar ferromagnetic member which is operatively connected to the bendable piezoelectric lamina at a region remote from the first edge, a dot print element mounted the movement of the bendable piezoelectric lamina along a line parallel to the plane of the planar ferromagnetic member, control means for generating first or cond voltage signals for energizing the bendable piezoelectric lamina to cau the planar ferromagnetic member to assume a first or a cond position, and electromagnetic means for applying a controllably variable 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 with the diameter of the dot being a function of the force.
