Abstract
An improved high speed impact matrix printer is provided for use with data processing systems and digital communication systems. In the serial wire matrix printer (10) of the preferred embodiment, a printhead (36) has print wires (90) arranged as a column within a wire guide (88). The printhead (36) is stepped serially across a print record, and print wire drivers (68) fire the print wires (90) in accordance with character configuration information in storage to effect the printing of a line of characters. The impact head of each print wire (90) is elongated with its longitudinal dimensions extending in the direction of relative movement of the printhead (36) along the print line. The elongated impact head of the print wire (90) extends over a plurality of print firing locations of a matrix character pattern to reduce the number of times the print wire drivers (68) must fire the print wires (90) to print a character.
