ABSTRACT:
A photographic printer has at least two film carriers which are moved together in a direction perpendicular to a film transporting direction. A photographic film is subjected to light measurement while drawn out from a film cartridge on the first film carrier and, simultaneously, another photographic film is subjected to printing while rewound back into a film cartridge on the second film carrier. The printing is performed according to the result of previously performed light measurement. Upon completion of the printing in the second film carrier, the respective film carriers are moved to change over the operation steps such that the photographic film on the first film carrier is subjected to printing, and that the film cartridge into which the printed photographic film has been rewound is replaced by a new film cartridge on the second film carrier.
