THE TRAVELING DIRECTION OF A SHEET IS CHANGED FROM THE FIRST DIRECTION TO A SECOND DIRECTION BY A DIRECTION CHANGING UNIT (20). A FIRST OUTPUT UNIT (9) AND A SECOND OUTPUT UNIT (12) TO WHICH PRINTED SHEETS ARE BOTH OUTPUT IN THE SECOND DIRECTION ARE INCLUDED, AND THE FIRST OUTPUT UNIT (9) AND THE SECOND OUTPUT UNIT (12) ARE ADJACENT TO EACH OTHER. THE DIRECTION CHANGING UNIT (20) CHANGES THE TRAVELING DIRECTION OF A SHEET FROM THE FIRST DIRECTION TO THE SECOND DIRECTION. IN DUPLEX PRINTING, A SHEET SUPPLIED FROM THE FIRST INPUT UNIT (3) IS SUBJECTED TO PRINTING ON A FIRST SIDE THEREOF IN A FIRST PRINTING APPARATUS (1) AND THE TRAVELING DIRECTION THEREOF IS CHANGED IN THE DIRECTION CHANGING UNIT (20) WHILE THE SHEET IS REVERSED, AND THEN THE SHEET IS SUBJECTED TO PRINTING ON A SECOND SIDE THEREOF IN A SECOND PRINTING APPARATUS (2) AND OUTPUT TO THE SECOND OUTPUT UNIT (12). IN SIMPLEX PRINTING, A SHEET SUPPLIED FROM THE FIRST INPUT UNIT (3) IS SUBJECTED TO PRINTING ON ONE SIDE THEREOF AND THE TRAVELING DIRECTION THEREOF IS CHANGED IN THE DIRECTION CHANGING UNIT (20), AND THEN THE SHEET IS OUTPUT TO THE FIRST OUTPUT UNIT (9). THE TRAVELING DIRECTION OF A SHEET THAT HAS BEEN SUPPLIED FROM THE SECOND INPUT UNIT (6) AT THE SAME TIME IS CHANGED IN THE DIRECTION CHANGING UNIT (20), AND THE SHEET IS SUBJECTED TO PRINTING ON ONE SIDE THEREOF IN THE SECOND PRINTING APPARATUS (2) AND OUTPUT TO THE SECOND OUTPUT UNIT (12).
