PURPOSE:To prevent print dots from being shifted and enhance printing quality, by a system wherein the difference between a current-passing time for single- stroke printing and that for consecutive printing is calculated, and the current- passing timing for consecutive printing is delayed behind the current-passing timing for single-stroke printing by the amount of the difference. CONSTITUTION:Timers 20, 21 are started operating by an input of a timing signal (f). Current-time printing data RA1-RAn inputted into a register 18 are ANDed with an output from the timer 20. In addition, the AND of an output signal g1 from the timer 20 and an inverted signal of an output signal g2 from the timer 21 is ANDed with preceding-time printing data RB1-RBn stored in a register 19 to produce a signal g3, and the printing data RA1-RAn are ANDed with the signal g3. accordingly, the current-passing timing for consecutive printing can be delayed behind that for single-stroke printing by a predetermined delay time, so that the current passage finish timing in the consecutive printing can be made to accord with that in the single-stroke printing. |
