Interesting project. I did something similar with a raspberry Pi I had laying around and a receipt printer. I installed the serial print driver, then just apt installed the avahi and cups daemons. It was then accessible to everything else on my network. I later made a nice little web UI that allowed you to write (or upload) whatever and get it printed. (Along with a messaging bot that allowed you to send it anything cups will ingest like .png or .pdfs or raw text. It was a fun little project that also let me print files to my real printer when I wasn’t even home!).
