ABSTRACT:
A thermal transfer printer includes an arrangement for continuously and automatically varying the rate of advance of the thermal transfer ribbon during printing, the rate of advance being correlated with the nature of the image being printed, and the variable advance rate being provided by a driven friction feed roller and a pair of ribbon guides which cooperate with the friction feed roller and are so positioned that the transfer ribbon is held tightly against the friction feed roller, contacting the circumference of the friction feed roller over more than 90.degree. its circumference and preferably at least 180.degree. of its circumference.
