A computer coordinated microfilm jacket feed and printer machine has a microfilm jacket aligning and feed structure and a microfilm jacket-stacking and aligning platform and elevator thereof. The jacket-feed mechanism positions a forwardly-stacked microfilm jacket in a predetermined pick-up position at which vacuum-oriented pick-up ports of a pivoted pick-up structure suction-attaches a forwardly-advanced feed microfilm jacket, and by the pick-up structure pivoting and injecting the jacket into a printer's platen's input-bite (input-bite position) and guides therefor. The computer activates the platen roller which thus pulls through the microfilm jacket to a print position after turning-off the suction cup's vacuum; the entire machine and computer combination turns-off if the transport mechanism fails to pick-up and transport the printed jacket. The computer causes the printer to print the preprogrammed message or other writing or code onto the microfilm jacket, while concurrently the suction cups are returned to the jacket pickup-position and the suction cups thereupon pick-up the next-occuring jacket, thereafter positioning it at a ready-position for its eventual feed into the intake bite of the printer's platen and guides thereof. A transport mechanism grips and transports the printed jacket to a stacking elevator-controlled stacking tray, when-after printing is completed, the computer causes the printed jacket to eject. Concurrently, during ejection if the printed jacket, the next unprinted jacket is fed into the printer and advanced to a printing position.
