PURPOSE:To eliminate variance in printing position by arranging a printing mechanism part so that the part reciprocates slantingly by a specific angle to the conveyance direction of paper, etc., and moving the mechanism part forward in synchronism with the conveying speed of the paper, etc. CONSTITUTION:The paper 1 or the like is conveyed at a constant speed as shown by a arrow 2. The mechanism part starts printing operation according to a preset period when a printing head 4, i.e. dot 5 reaches a position corresponding to the preset printing position l of the paper 5, etc., after the end of the paper 1, etc., passes through a photoelectric sensor 3. Further, the printing head 4 is moved forward slantingly by the angle theta to the conveyance direction of the paper, etc., at a speed V/costheta, where V is the conveyance speed of the paper, etc. Assuming that the paper 1, etc., stop, the movement of the printing head 4 to the paper, etc., is in the direction of a symbol 16 slanting by the angle theta of the conveyance direction of the paper, etc., but the paper, etc., moves actually, so a lateral print is made on the surface of the paper at right angles to the conveyance direction of the paper, etc., i.e. laterally as shown by a symbol 17.
