Each print wire in the print head of a printer is moved by an electromagnetic actuator which includes a stator with pole faces defining gaps and a slider which is formed with armature members which cooperate with the gaps. When a coil on the stator is energized, the armature members tend to move into the gaps and cause the slider to operate the print wire. The arrangement is illustrated diagrammatically in the figure, which is a side view of a print head assembly cross-sectioned on its longitudinal axis. The print head assembly includes a conical core 1 around the periphery of which are mounted a plurality of electromagnetic actuators 2.
