You get what you pay for, I guess.

Big expensive printers tend to be based around IPP and Ethernet, and you can feed them PostScript or PDF data to print directly without having to convert everything to pixels yourself first. Linux supports that pretty well. It's the el-cheapo proprietary stuff that can become annoying.

FWIW, Mopria is aiming to make the el-cheapo printers behave a lot like the big expensive ones, by providing a spec that (coincidentally for legal purposes) is a subset of Apple Airprint and Apple Airscan, thus being able to promise that if you follow the Mopria spec, your printer will work out of the box on any recent Windows, Android, Apple or ChromeOS device without the need for the user to install software, but with support for your branding and your special features.

Combine this with Microsoft making installing new printer drivers harder, and the need for OpenPrinting declines - instead of needing support for proprietary formats over proprietary protocols over TCP or USB, you need support for Mopria PDF subset over Mopria IPP subset over TCP or USB.

FWIW, this seems to be the direction CUPS is going as well with CUPS 3.0. Well, it's called "IPP Everywhere", which AFAIU is more or less the same thing as Mopria. Everything not IPP Everywhere is legacy support handled by "printer applications", which take care of format conversions and whatever wire protocol is needed.
