There's also a kind of super-cheap Bluetooth "Chinese" thermal receipt printers, also known as "kitty printer" or "cat printer". There's plenty of reverse-engineered software for printing to them in a number of languages; one I use is: https://print.unseen-site.fun/ The disadvantage is they don't cut automatically, and their "cutter teeth" are super crappy. But cheap!
I have a version without cutter teeth at all, what I did was take a piece of the cutter thing from an aluminum foil roll and attach it to the printer. Works perfectly. Looks a little menacing though.
