Abstract: A printer is disclosed having type members carrying type characters, the members being yieldably advanced past a printing point and arrested by electromagnetically actuated pawls which are yieldably maintained in both retracted positions and arresting positions by snap-over springs. Abutments on the type members engage the pawls when the type members are in home positions to prevent accidental movement of the pawls to arresting positions. The electromagnetically operable means comprises pairs of side-by-side magnet modules in which each module is effective to retain the parts of an adjacent module in place.
