"many high-end photo printers aren't supported under Linux "
But most printers, and especially "high-end" ones will come with a USB that allows you to just plug in a thumb drive and print straight from it. Even the cheap Brother printer I got from a big box store can print from PDF, XPS, PS, and so on. Plus it gives me a backup of what I printed.
I was printing like that long before I moved away from Windows because 99% of the time, the printer driver will come with all sorts of random crap along with the piddly single-megabyte .sys file I actually care about. The last printer driver I installed was a 250 MB download that also installed a buggy update service, a 'photo manager', some trialware image editor, and constant pop-ups telling me that my supplies were low and should buy at an inflated price from the manufacturer's online store.
