>but it's one of those projects that feels like it's going to end up being a rabbit hole.

I know your feelings. I've started https://printserver.ink because I wanted to buy a retail print server and could not find any. I was expecting half a year overall work for everything, but fixing all printer-related bugs for 3 years already.

Ah nice. If I supply my own raspi zero 2W, can I buy just a software license from you? Doing the software integration is the part I'm least looking forward to. :(

Unfortunately the firmware supports only Orange Pi Zero3. It's a hardware+software solution, because to make reliable print server, you have to control both and fix SoC/board specific bugs.

For example, USB 1.1 OHCI has too high latency to work with my old printer, and needs a kernel patch: https://lore.kernel.org/linux-usb/3fe845b9-1328-4b40-8b02-61...

Greg does not accept my patch and does not reply to me, presumably because I'm Russian and he doesn't want legal consequences.

Raspberry Pi unfortunately have quite list of USB hub bugs and Wi-Fi module bugs (according to their GitHub and reports all over the Internet), and I'm not familiar with it and don't know how to fix. That's why I don't make generic firmware or container images, and stick only to my board which I know from start to end.
