It's for controlling DMX colored lights over network. It takes UDP packets (and later Websocket messages) and turns them into DMX protocol packets which get sent over USB serial adapter to the DMX wire. It's a rewrite of a previous node.js version which had bitrotted.
I think I made the MVP in about 7 hours during one saturday afternoon. Finishing it up took a few weeks more of evenings.

The TXT records are based on the Bonjour Printing Spec [0] which list out which fields so it knows the type of the printer and it uses the SRV port to find the ipp port so it can contact the printer.
Further investigation using rvictl (iOS packet sniffing) showed the IPP traffic, which is really http API. It is via this API that iOS determines what paper is supported from what tray.
The path is then clear: create my own mDNS service that returns a printer on my own port, this IPP port acts as a reverse proxy to the real printer's IPP port, but it modifies the "media-col-ready" attribute to make iOS think A6 is loaded into the manual try.
It was extremely painful, but it was done: https://github.com/LittleLightLittleFire/fakeprinter
