Hi Mike,
ALPS are older printers (as far as I know, they don’t make them anymore), but there are drivers available online for MacOS Windows (XP up to 7).
It connects via parallel port (the big, older printer cable, pre-USB), so you’d need a parallel to USB-to-parallel adapter or a parallel port card. I had an old parallel pcie card in my PC when I used it.
You can still get inks, accessories, etc online even if the printers are out of production.
