ABSTRACT:
Envelopes (9) are fed flap first and flap closed long dimension first into the nip of fixing rollers (3,4). The fixing rollers are less wide than the envelopes, and the printing system does not print on the edge of the envelope which is not fixed.
Since this adds very little to the apparatus and software, wrinkle-free envelope printing is achieved at very low initial and overall cost.
