Abstract
A printing device, in particular a printer or a copier, and method for its operation which includes a first electrographic printing unit for printing an image pattern on a sheet-type material in a first transfer printing transport path as well as a second electrographic printing unit for printing an image pattern on a sheet-type material in a second transfer printing transport path, and further including 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, and further having an output section via which the printed sheet-type material from either the first or second electrographic printing units is ejected individually one after the other. The first and second printing units are in first and second transfer printing transport paths that are connected by connecting paths that form first and second rings. The first ring has a supply channel, the second ring has a carry off channel and a two direction connecting channel is between the first and second transfer printing transport paths.
