ABSTRACT:
A printer for reducing the consumption of a ribbon at a printing completion section. A ribbon feeder feeds an ink ribbon so as to carry out printing during a period in which heat transfer is being effected on recording paper. Further, the ribbon is continuously fed to a blank area or portion existing in the printing to determine the printing. When a final portion detector detects a final area or portion to be printed during the continuation of feeding of the ribbon toward the blank portion or during a period in which the feeding of the ribbon to the blank portion is stopped to wait for recommencement of the printing, a difference calculator calculates a difference between a feed length of a ribbon required to determine the printing and a length of a ribbon fed toward a blank portion calculated by a blank feed length calculator. Further, the ribbon feeder continues to feed the ribbon by the calculated difference, to thereby fix printing characters subjected to the heat transfer onto the recording paper.
