Some systems still talk serial. Your legacy software, your older controller — they want an RS-232C port and a 25-pin D-shell to plug into. This Lexmark serial interface card (part 27X0900) slots straight into the printer's internal port and gives you that standard RS-232C connection with a 25-pin D-shell female connector. No USB-to-serial dongle dropping mid-job. No workaround software. Install the card, run your cable, and the old setup keeps doing its thing. Sorted
