ABSTRACT:
The invention relates to a printing or copying device having a photoconductor drum (10) for receiving two adjacently arranged toner images for a recto and a verso of a recording medium (15). Provided for the simultaneous transfer of the toner images onto the recording medium (15) are two separate transfer ribbons for the recto toner image and the verso toner image. In this case, one transfer ribbon is deflected over a deflection device in such a way that the transfer ribbons (T1 and T2) are positioned one above the other in a fuser station (19) designed as a thermal printing fuser station. The recording medium (15) is passed between the transfer ribbons (T1 and T2) and is thus printed verso/recto simultaneously.
