A print mechanism is described which has a constant current driven solenoid acting against an arch-shaped hammer to power the hammer through an arc of powered flight followed by an arc of free flight. The solenoid/hammer engagement point removes the solenoid to a position which does not obstruct print line visibility and the hammer rest position is withdrawn to improve print line visibility.
