Multi-functional printer device having modular structure

A multi-functional printer device for printing web-shaped recording media with different web widths, comprising:

• an electrographic printer module comprising a usable width of at least twice a web width of a narrow recording medium, said printer module containing a means for generating toner images and a thermal fixing station with a paper output channel via which the recording media leave said printer module, as well as a delivery channel in order to supply recording media of different web widths from one of an internal and external supply region to said means for generating toner images;
• a turn-over module that can be coupled to said paper output channel via a return channel and to the delivery channel, said turn-over module being constructed as an independent structural unit that can be interchangeably secured in the printer module, whereby
• in a first operating mode of said printer device for two-sided printing of the narrow recording medium, the recording medium for printing the front side passes through said printer module up to said paper output channel of said fixing station proceedings from said supply region and, for printing a back side of said recording medium, is resupplied to said printer module therefrom via said return channel and turned over via said turn-over module, and is output via said paper output channel of said fixing station, and
• in a second operating mode of said printer device for single-sided printing of one of an individual broad recording medium and parallel printing of a plurality of narrow recording media, the recording medium or media pass through only said printer module, proceeding from said supply region, and are output via said paper output channel.
