Abstract

The printer operates as described below while counting, with the copy counter, the number of printed copies. The odd-numbered copy is printed on the front surfaces of the papers form the first page to the last page in this order and is discharged facing downwardly. The even-numbered copy is printed on the backside surfaces of the papers from the last page to the first page in this order an discharged facing upwardly. Accordingly, in the printed matter finally stacked on the discharge tray, the printed sheets are stacked so that the surfaces, on which images are printed, are alternated in the respective copies.
