A second calculating unit 5 calculates the paper feeding motion time for starting the printing of the next line after the printing of one line has been completed. A comparison unit 6 compares the return motion time which is calculated by the first time calculating unit 4 and the paper feeding motion time which is calculated by the second time calculating unit 5. A motor driving control unit 7 starts the motion which has a longer time at the same time with the head up motion, according to the result of the comparison by this comparison unit 6, and starts the other motion after the head up motion has been completed. By this method, the number of motors to be driven simultaneously is limited to two, and the increase of power consumption can be suppressed.
