A photographic film, which is accommodated in a cartridge provided with a storing element for storing printing information, is separated from the cartridge. An identification mark for having the film and the cartridge correspond to one another is applied to the film. The printing information stored in the storing element is read by a first reading device. The printing information read by the first reading device and the identification mark are stored in correspondence with each other. The printing information corresponding to the identification mark applied to the film is read by second reading device. In accordance with the printing information read by the second reading device, an image recorded on the photographic film is printed onto a photographic printing paper in a state in which the cartridge and the photographic film are separated from each other.
