A printing method and apparatus wherein the circumference of a drum is shorter than the length of paper so that the paper is wound around the drum with the top and bottom ends of the paper overlapping by a predetermined length. Printing begins at a position spaced apart from the leading edge of the paper by the difference between the circumference of the drum and the length of the paper. An ink ribbon contains colorless portions, whose lengths are equal to the predetermined length, which is equal to the difference between the circumference of the drum length of the paper, at the borders of respective portions. Respective colors are serially printed when a printing head presses the ink ribbon. When the printing head presses the overlapping portion of bottom ends of the paper, the colorless portion of the ink ribbon passes the printing head.
