ABSTRACT:
In an auto-printer, wherein original frames to be printed are sequentially and automatically printed at an optimum exposure amount, which is determined based on frame specification data which includes exposure correction data, frame number and position data and stored during negative inspection. The frame position data is compared with an actual amount of film advancement detected when advancing the frame toward a print position, so as to determine whether the frame specification data corresponds to the actual frame placed in the print position. Simultaneously, the actual frame number of the frame placed in the print position is determined based on frame number bar code read from the photographic film during advancing the film, so as to compare the actual frame number with the frame number data. If it is determined by either one of the above described comparison that the frame specification data does not correspond to the actual frame, the auto-printer is automatically changed from an auto-print mode to a manual print mode.
