The apparatus includes a decision unit for deciding whether or not a shuttle carrying the printing unit should be stopped during the reversal of the motion in accordance with printing information supplied to a unit for controlling the driving of the shuttle and the condition of feeding of the paper; reversing motion stopping means for stopping the reversing motion of the printing unit and holding it in the stopped state by supplying reversing stopping information to the printing operation control means when the paper feeding time of the paper to be printed is greater than the time of the reversing motion of the printing unit; and releasing means for releasing the stopping of the reversing motion of the printing unit in relation to the timing of termination of paper feeding of the paper to be printed and restarting the printing from a printing starting position. Therefore, the printing operation is restarted i…
