The printing mechanism is engageable with the type member to effect printing on a sheet of printing paper. The selection mechanism comprises a locking member for alternately catching and locking the first and second outputs, an action member for acting on the locking member to catch and lock the second output when the locking member is in a standby condition and to catch and lock the first output when the locking member is in an operating condition, an electromagnetic trigger member for shifting the locking member from the standby condition to the operating condition, and a return drive member supplied with the second output for acting on the locking member in order to return the locking member from the operating condition to the standby condition.
