摘要：
A dot matrix printer having a printer hammer bank carried on a frame to allow movement parallel to the platen. A balancing member is suspended from the head hammer bank by resilient springs and carries a motor for driving the head hammer bank in a reciprocating manner. A linkage further couples the head hammer bank and the balancing member so that the balancing member moves in a direction opposite to that of the head hammer bank.
