PURPOSE:To prevent the shift of a printing position, by regulating the number of rotations of a paper feed motor by prividing a paper feed counter for counting the number of residual pitches of the number of pitches for rotating the paper feed motor at once when a multiple-pitch feed mode is set. CONSTITUTION:The rotary speed of a stepping motor 19 is high as compared with an one-pitch feed mode before the number CN of residual pitches during the practice of a multiple-pitch feed mode is lowered to a limit value A and shift is generted between both feed modes. However, when the number CN of residual pitches are lowered to the limit value A or less, the number of rotations of the stepping motor 19 are gradually lowered to gradually reduce the shift of the one-pitch feed mode. When the final remaining pitch comes to 1, the number of rotations of the stepping motor 19 becomes equal to the number of rotations of the one-pitch feed mode. As a result, the shift between multiple- pitch and one-pitch feed modes comes zero.
