The electrothermal printer and displays are connected directly to the interface card (chapter 4.3 and 7.7) which interconnects all the
mechanisms situated in the upper, tip-up part of the cash register. Two 15-conductor cables, situated in the grooves of the tip-up
construction, connect the printer to the mainboard.
