Abstract
A dot matrix shuttle printer and/or a module therefore uses print wires of different lengths so as to achieve desired close packing of individual print wire actuators and correspondingly close wire-to-wire spacing of the print wires. To help maintain synchronization between the operation of all print wires, the longer ones include hollow sections so as to cause all the print wires to have substantially equal mass in spite of their differing lengths. The longer print wires include a hollow tube of stainless steel. A tip of wear resistant material is fixedly inserted at one end of the tube to effect impact printing.
