I set up a raspberry Pi W with cups and Air Print to an older Brother laser over USB. Now I can wireless print from all my devices and keep this beast going for longer.
Nice workaround. I run a container with CUPS set up for Air Print as well but I’m using it only with some somewhat-compatible driver for different model. I suppose I could spend more time on it and see if I can make it work with one of the official Linux drivers and have a full blown support.
