In a receipt printer (10), suitable for printing on a paper ribbon of different widths, wound on a roll (14) arranged in a seat (15, 22, 23, 24) in the printer, a wall is provided for the lateral positioning (18, 30) of the roll of paper (14) in its seat, to keep the paper ribbons, or the respective rolls (14a, 14b) of at least two different widths in the proper printing position, independently of the width of the ribbon; the positioning wall (18) is arranged inside the seat (15) of the roll of paper, with a first surface (44) facing a side (26′) of the same roll (14a).
