Abstract

A wire fire control mechanism is provided for use in a wire matrix printer for controlling the firing of the print wires (44) as the printhead (24) moves across a print receiving medium (40). This wire fire control mechanism enables printing to be accomplished for a wide range of different printhead (24) speeds. It also enables printing to be accomplished while the printhead (24) is accelerating or decelerating.
