The short answer is you either use an older motherboard with a built-in parallel port, or you use an add-in card that adds a port via PCIe. As far as I understand, the PCIe cards are “real” parallel ports, but USB to LPT adapters don’t work properly for anything that’s not a printer.
How does one use a parallel port device now-a-days?
