I did see an Oki 182 quite cheap - I'll check it out.

The Oki 182 isn’t the speediest printer on the race track, but it’s rugged and understands the Epson LQ-series escape sequences. I think it will also accept Oki’s serial interface card, but can’t recall at the moment. If I were you, I’d grab it while it’s still available.

As Ed noted, TIA-232 is the true “universal serial bus” (though technically not a bus) that makes connecting a wide variety of peripherals a practical matter.

Well, I'd say that the TTY asynchronous start-stop protocol is that. These days probably most serial links are not at all TIA-232 (which requires negative voltages), though they still use TTY async start-stop. (My use of async start-stop at 0V/5V is extensive; my use of TIA-232 is only with my vintage computers that happen to have that port built-in.)
