ABSTRACT:
A printer comprises a platen roller for supporting and feeding a cut sheet, a first motor for rotating the platen roller and a tractor for feeding a continuous paper. The tractor is capable of being connected to the first motor through the platen roller. The printer comprises a second motor having first, second and third phases based on a rotational angle. A clutch can be connected to both the platen roller and the tractor and can be disconnected between the platen roller and the tractor based on driving force from the second motor. A paper bail roller is faced with the platen and the platen bail roller can be moved between a position contacting the platen and a position separated from the platen by paper bail roller moving unit based on driving force by the second motor. The first phase of the second motor corresponds to a position where the paper bail roller is separated from the platen, the second phase of the second motor corresponds to a position where the paper bail roller contacts the platen roller and that clutch connects the platen roller and the tractor, and the third phase of the second motor corresponds to a position where the paper bail roller contacts the platen roller and that clutch disconnects the platen roller from the tractor.
