    Abstract: A printing device includes: a printing unit printing on a recording paper; a feeder unit that has a roller rotating in a first direction about a shaft and feeding the recording paper, and a motor rotating the shaft; a detection unit detecting a rotation of the shaft in the first direction and a rotation thereof in a second direction opposite to the first direction; and a control unit controlling the feeder unit, based on the rotation of the shaft detected by the detection unit. The control unit causes the motor of the feeder unit to rotate the shaft in the first direction and then stop the shaft, and subsequently causes the motor to rotate the shaft in the first direction before the printing unit prints, based on the rotation of the shaft in the second direction detected by the detection unit.

    Abstract: A printing device includes a transport roller performing a first transport that transports recording paper drawn from roll paper in a transport direction and a second transport that transports the recording paper in a direction opposite to the transport direction, a cutter having a first blade configured to move between an advanced position and a retracted position, and a second blade for cutting the recording paper together with the first blade moving from the retracted position to the advanced position, and a guide member provided downstream of the first blade in the transport direction and guiding the recording paper during the second transport.

    Abstract: A roll paper printer includes: a case configured to accommodate a paper roll in which paper is wound in such a way that one surface of the paper faces outward; a transport roller that pulls the paper from the paper roll and transports the paper in a transport direction; a first paper guide configured to come into contact with the other surface of the paper upstream of the transport roller in the transport direction; a second paper guide that faces the first paper guide and is configured to come into contact with the one surface of the paper; a third paper guide configured to be attached/detached and configured to come into contact with the one surface of the paper and curve the paper upstream of the second paper guide in the transport direction; a sensor configured to detect the third paper guide; and a controller that decreases, when the third paper guide is detected by the sensor, a transport speed for the paper transported by the transport roller to be lower than that when the third paper guide is not detected.

    Abstract: A printing apparatus includes: a roll sheet container that contains a roll sheet around which a recording sheet is wound; a first sheet guide that makes contact with a first surface of the recording sheet; a second sheet guide that makes contact with a second surface of the recording sheet; and a transport roller that transports the recording sheet. The first and second sheet guides are disposed so as to face each other to form a sheet route along which the recording sheet is to pass. The transport roller transports the recording sheet that passed along the sheet route. The second sheet guide includes: a projection that protrudes toward the roll sheet container; and a pushing section that extends from the projection along an outer circumference of the roll sheet and in a direction away from the first sheet guide.

    Abstract: A printing apparatus includes: a roll paper container portion that accommodates roll paper formed into a roll by wrapping recording paper around a core; a transportation roller that transports the recording paper in a transportation direction; a buffering member that moves in contact with the recording paper; and a guide member that is provided upstream of the buffering member in the transportation direction and guides the core of the roll paper that is moved from an inside of the roll paper container portion to an outside.
