Actually most of the thermal doodads take ESCPOS which prints ascii serial.

You can literally spit text ascii text to it and it prints, if you want to
do fancy things, well then you can send ESCPOS commands to format bold and
even upload custom fonts and print bitmaps, using this code.


I've been messing around with a ZJ-85 connected to USB on a WebDT 166

I've also tested against a Bixolon SRP-275.

ESCPOS is (duh) for POS units and is very forgiving.
