ABSTRACT:
A printer-processor has a printing section for exposing images onto a part of a strip of photographic paper, a cutter for separating the exposed part from the strip to form a sheet, and a processing section for developing the sheet. After one printing, the strip is transported by feeding rollers to set an unexposed part of the strip in an exposure state while simultaneously releasing the exposed part from the exposure stage. This transportation is carried out, not immediately after the printing, but at least after a predetermined period from the time the previously-exposed part was cut so that the strip does not overtake the sheet which is being released into the processing section by another feeding rollers. Further, when or just before the strip is transported, releasing means releases nipping of the latter feeding rollers as not to disturb the transportation of the strip.
