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.
