Sam Ash (recently defunct U.S. musical instrument chain) infamously used a system called GERS with a TUI, the components of which IIRC were adapted from either a furniture or carpet store. Well into the 2000s, receipts were still printed in full size carbon paper (triplicate) on dot matrix printers. You'd get a gift "card" that was a literal greeting card with one sheet of that dot matrix printout stuffed in it.
