For each first digital image to be printed on the first side of the roll, a first location on the first side of the roll is established at which first location the first digital image is intended to be printed, a second digital image is established which is intended to be printed at a second location on the second side of the roll, the second location being the backside of the first location. The first entry of the first digital image in the digital image queue is then linked to the second entry of the second digital image in the digital image queue by means of a linking digital item in the digital image queue. The first digital images are printed on the first side of the roll according to the digital image queue, the one-sided printed roll is received in the input holder, and the second digital images are printed on the second side of the roll according to the corresponding linking digital items in the digital image queue.
