A multicolor printing system with a plurality of toner printing stations which apply differently colored toner images to at least one side of a transfer medium, from where the toner images can be transferred to a print medium which can be contacted with the transfer medium. If an endless transfer belt is used as the transfer medium, with a running direction extending at an angle with respect to the transport direction of the print medium, the toner printing stations embodied as modular units are arranged at exteriors of two sides of the endless transfer belt and are matched to the opposing running directions of the sides with the toner image transfer, and the multicolor toner image of the endless transfer belt can be transferred directly or via a transfer roller to the print medium which is conducted at the same speed as the endless transfer belt, then it is possible with small structural dimensions to arrange a plurality of toner printing stations in an easily accessible manner at the endless transport belt and to control them so that a congruent composition of the multi-color toner image and its unequivocal transfer to the print medium occurs.
