Abstract (en)
[origin: US4400101A] The print head of a matrix printer includes two columns of print wires held in separate members which are individually vertically displaceable as well as together in order to obtain different conditions for printing. Good quality or high-speed modes can be obtained in a single pass, high quality in two passes, or a single pass with alternating, vertical displacement of the members for each print position.
