ABSTRACT:
A serial impact printer including a platen mounted for rotation upon a support frame, a print element having character imprinting portions disposed thereon and a print element selector for moving the print element to position a selected character imprinting portion at a printing position. A high effective mass hammer, driven toward and away from the platen in a timed manner, drives each selected character imprinting portion for deforming the platen with a printing force. A carriage mounted for reciprocating movement generally parallel to the platen, supports thereon the print element, the print element selector, the hammer and the hammer driver, and a stationary reaction bar secured to the support frame is spaced from and extends parallel to the platen. The reaction bar incudes a reaction surface against which the carriage is urged for developing the printing force as the hammer deforms the platen.
