Abstract
A print mechanism has a laterally spaced longitudinally driven actuator or slider mounted between two electromagnets. By selective actuation of the electromagnets the slider is driven forward to strike a print element and produce printed information. A unique dampener assembly is provided to absorb recoil energy and maintain a fixed start position. The dampener assembly includes a return spring and a three layer damper that absorbs the excess recoil energy without experiencing permanent deformation.
