Abstract: For use in photographic package printing, selected negatives are cut from the film rolls and mounted in individual paper negative carriers, imprinted with bar-coded order details. A novel reader-feeder reads the bar-coded order on each of the carrier and stores the order in the memory of its microprocessor. When photoprinting of a prior order has been completed, the reader-feeder withdraws the prior negative carrier, feeds the newly-read negative carrier to the package printer, and inputs its stored order to a conventional printer-controller, which directs the photoprinter in the same manner as if an operator was key-inputting the order into the printer-controller.The paper negative carriers are supplied in manifold form, for computerized imprinting. These consist of die-cut front sheets having an adhesive backing on a waxed manifold web. Aligned rectangular cut-outs, the larger of which is in the web, provide an adherent mounting frame when the cut-out portions are removed.
