ABSTRACT:
A photographic printing apparatus has a supply spool with a flange which is movable in the lateral direction of the photographic paper to be used, a guide roller with a flange which is movable in the lateral direction of the photographic paper, a printing section, and a take-up spool with a flange which is movable in the lateral direction of the photographic paper. The supply spool, the guide roller, the printing section and the take-up spool are disposed in series. A continuous photographic paper wound in layers is loaded on the supply spool and is transported to the printing section through the guide roller, and the photographic paper printed therein is then wound up onto the take-up spool. All of the above-described flanges are moved in the lateral direction of the photographic paper to be printed in accordance with its width so as to restrict the lateral movement of the photographic paper, thereby preventing the photographic paper from meandering or moving in a zigzag direction when it is being transported.
