Conventional wire matrix print heads are solenoid-driven and are speed- limited because of their power dissipation. The packaging of the head is also a problem because of the need to dissipate the heat in the coils, which prevents compact design. Typical power requirements for solenoid-driven wire matrix heads is 9 watts per wire at 900 Hz.
