A printer includes a shell, a reversion module, a stick, a roller set, a first sensor, a second sensor, a first motor, and a second motor. The reversion module includes a housing, a first axis, a first gear, a second axis, a second gear, and a plurality of cannelures. The printer feeds a printing media into the reversion module, and drives the rotation of the reversion module to drive the rotation of the printing media so that both sides of the printing media are capable of being printed by the printer. The effect of reversible print without additional reversion of the printing media by bare hands is achieved.
