This is awesome! I have a very hacky prototype doing something similar, you've put way more effort into PrinterCow and it looks great.

What's the tech? (I'm crossing my fingers for Elixir/Nerves but I suspect that's still a bit niche)

Edit, I'm now signed up - though I'm struggling to find the install instructions for the RPi.

Thanks so much! Elixir was on my list but decided for Fastify (Node v22), Postgres and Vue3 in the end as these are the things I am more familiar with. :) The command is on the Printercow homepage - though proper docs are coming by end of the week.

(I meant for the Pi software)

Edit: had a look at the firmware and it's not Nerves - but that's fine! I was just curious :)

Raspberry Pi Installation: - Open Raspberry Pi Imager - Select Raspberry Pi OS Lite (32bit) --> Lite is without desktop environment and saves some Memory on the PI :) - Start the Pi and enter: curl -fsSL https://printercow.com/pi/install.sh -o install.sh \ && chmod +x install.sh \ && sudo ./install.sh
