ABSTRACT:
A duplex printing device including a duplex printing master on which two images are perforated in series over a single plate, and a simplex printing master on which a third image is perforated over the single plate. Either master is wrapped around an outer peripheral surface of a print drum, enabling duplex printing operation in which one of the two images is printed by pressing a front side of a sheet against the duplex printing master on the print drum using a presser which can be brought into and out of contact with the print drum, after which the other image is printed by reversing and refeeding the sheet and pressing a reverse side of the sheet against the duplex printing master on the print drum using the presser, and a simplex printing operation done by pressing one side of the sheet against the simplex printing master.
