Abstract
A printer for printing a row of characters on a recording medium. The printer includes at least first and second type rings having types disposed on the periphery thereof which are rotatable from a reset position to a print position. First and second pawls are associated with the first and second type rings, respectively. A control member moves the first pawl into engagement with the first type ring when in its reset position to prevent rotation thereof. The second type ring is rotated into a print position while the first type ring is held in its reset position by the first pawl. A lever associated with the first and second pawls is actuated by an electromagnet to move the second pawl into engagement with the second type ring when in a print position to stop the rotation thereof. The control member releases the first pawl from the first type ring which then rotates to a print position. The lever is then reactuated by the electromagnet to move the first pawl into engagement with the first type ring when in a print position. A positioning member positions the second pawl out of engagement with the second type ring and also acts to hold the second pawl in engagement with the second type ring when the second pawl is moved into engagement with the second type ring.
