ABSTRACT:
Printing apparatus of the dot matrix type comprising a plurality of print wire actuators employing moving coils. The wire printing tip of each actuator is activated by the coil magnetic field interacting with an efficiently applied magnetic field substantially perpendicular to the direction of current flow in the coil. The actuator comprises a thin planar lamination having low inertia and high heat dissipation for balanced pivotal motion to provide high speed letter quality printing and high resolution graphics.
