Reverse-engineered CUPS driver for Phomemo receipt/label printers

Agh, I got myself a Niimbot D110 because it seemed to be the best supported "cheap" label printer (using the excellent https://niim.blue/ website).

If I knew these printers had CUPS drivers I might have gone that way instead..

Have been tempted to get one of these just for printing out tickets/QR codes so I can keep my dumbphone and not fight dried up ink cartridges etc.

Is there a device you can recommend for printing (sticky) labels occasionally? I have a little Brother printer for those narrow little labels, one with a rubber keyboard, but would love something with sticky labels AND Linux connectivity. Something I could script when organizing my workspace, parts, ... to print the appropriate label.

Are these devices popular? My friend has two and is excited about them, but I have no exposure to them outside of that, so it's cool to see it pop up here.

Does anyone know any good wifi printers receipt printers?

The only one I could find was Epson TM-30III but it's like 280E here.

I've been using labelle (on github) with my Dymo labelmaker on Linux and it's been great.

Is there a driver for the cat printer? :D
