Show HN: Printercow – Turn any thermal printer into an API endpoint

I've always been fascinated by thermal printers – there's something magical about seeing text and images materialize on paper in seconds.

Ask HN: Organize local communities without Facebook?

I want to move our local communities off Facebook and onto our own platform. Is there a off-the-shelf solution or any collaborators I can join to move something along?
