I wrote some software with two other guys for a restaurant in Copenhagen. I did the backend for an automated seat allocation system, while other guys wrote a web app for browsing and ordering menu items. The restaurant insisted that the orders be printed as paper slips, while the guys had imagined a PC running the ticket system software (that the chefs would interact with). In the end they did exactly what the linked post describes (but for another ticket system — Zendesk IIRC): an RPi connected to a thermal ticket printer, using some open source library for converting from the ticket data fetched from the API to the format required by the printer.
