Beschreibung
Zusammenfassung:	A printing apparatus includes a printing cylinder (14) that can hold sheets (4) and transfer them one by one continuously, first to fourth inkjet heads (41 - 44), and a feeder unit (2). The printing apparatus includes a speed reducer (72) that switches the speed of the feeder unit (2) between single-sided printing and double-sided printing. In single-sided printing, the feeder unit (2) is driven at a first supply speed at which the sheets (4) are supplied to the printing cylinder (14) one by one continuously, and the printing cylinder (14) is driven at a transfer speed at which the sheets (4) supplied from the feeder unit (2) one by one continuously are transferred. In double-sided printing, the printing cylinder (14) is driven at the transfer speed, and the feeder unit (2) is driven at a second supply speed that is 1/2 the first supply speed. The printing apparatus that operates stably in both single-sided printing and double-sided printing can be provided.
