Abstract

An apparatus for double-sided printing of identification cards (1) has a printing unit (2) with a thermal printhead (17), a card transport device, an input sensor (8) and an output sensor (9) as well as a reversing unit (3) for reversing and further transporting the printed card (1) which is provided with a rotor (36) with a rotating card transport device. The card transport device on the rotor (36) is controlled so that it feeds the card (1) printed on one side and turned by 180.degree. to the printing unit (2) again without changing its direction of rotation. The card transport apparatus of the printing unit (2) is switchable from the forward to the return transport direction (A and B, respectively) for return transport of the card (1) from the output sensor (9) to the input sensor (8). When the card (1) reaches the input sensor (8) upon return transport, the card transport device is switched back for printing the other side of the card (1) and feeding it to the reversing unit (A) again.
