Abstract:
A printing device, comprising:a first electrographic printing unit for printing an image pattern on a sheet-type material in a first transfer printing transport path;a second electrographic printing unit for printing an image pattern on the sheet-type material in a second transfer printing transport path;an input section via which the sheet-type material can be supplied individually one after the other to both the first and second electrographic printing units;an output section via which the printed sheet-type material from both the first and second electrographic printing units is ejected individually one after the other; andfirst and second rings formed from the respective connection of the first and second transfer printing transport paths via connecting paths, wherein the first ring includes a supply channel via which the sheet-type material can be supplied to the second transfer printing transport path from the input section and the second ring includes a carry-off channel via which the sheet-type material printed by the first printing unit can be supplied to the output section, wherein the sheet-type material printed by one of the first and second printing units in a first print process can again be supplied to the same printing unit such that the sheet-type material runs through the same printing unit in the same direction as in the first print process, and wherein on the first ring a first shunt is provided by means of which the sheet-type material in the first ring can be turned over, and on the second ring a second shunt is provided by means of which the sheet-type material in the second ring can be turned over.
