A cutter of a printer including a rectangular housing in which a paper feeding roller and a fixed blade are integrally coupled to each other. The cutter includes a movable member corresponding to a plate-shape member having a slot at the center of a body provided at an upper side of the housing corresponding to the fixed blade such that a movable blade at one side is engaged with the fixed blade while being selectively reciprocally moved. The cutter includes a motor within the housing generating a forward or reverse driving force, a gear unit including a driving gear installed in a driving shaft of the motor, a reduction gear engaged with the driving gear and an idle gear engaged with a shaft gear. The cutter includes an eccentric plate coupled to an upper surface of the driven gear for applying external force for reciprocal motion to the movable member.
