Printhead overheating is a problem common to matrix wire printers. Temperature is frequently controlled by the simple expedient of limiting the number of wire-fires for each actuator, and for the printhead, during a given time interval. This micro-code controlled system reduces throughput and consumes printer processor bandwidth. A simple forced air cooling system is provided, for a known printer, which permits operation at rated speed.
