Abstract
A printer prevents color smear when a paper roll mounted on the printer is initially fed. The printer includes a plurality of printing units each having a thermal head and an ink ribbon, and a platen roller having an outer surface opposite the plurality of printing units. The platen roller can be rotated by a stepping motor. A printing medium is arranged on a roll at the most upstream side of the delivery path. A printed result of a predetermined printing length is obtained by sequentially transferring an ink to the printing medium from the upstream to the downstream printing units in an overlapping manner. The electrification period of the thermal head in each printing unit is controlled on the basis of an amount of rotation of the platen roller.
