This repo contains some docs and findings related to receipt printers and their various quirks. I'm interested in collecting as much of this information as I can as I just think they're neat. If you have something to add please feel free to open an issue!
To facilitate local dev you can spin up a local static webserver that will end up operating very similar to GitHub Pages. Clone the repo, run npm ci and npm run serve-local. On the first time this will run mkcert and save the certificate to your machine store, subsequently it will re-use this same cert. Open the server at https://localhost:4443/demo/ to test the app.
