Abstract
A thermal printer is disclosed in which a receiver is driven back and forth relative to a printing head by a driving roller. The receiver is driven at a nip formed between the driving roller and a pinch roller. The pinch roller is adapted to contact only the receiver during the movement of the receiver. The receiver is thereby permitted to move at the surface speed of the driving roller with reduced shear forces being introduced by the pinch roller. Consequently, a pinch roller with a high length to diameter ratio is usable and images can be produced on wide receivers with narrow image-free borders. The images are produced with precise registration and image artifacts are reduced.
