There's "driverless" printing in the form of Mopria https://en.m.wikipedia.org/wiki/Mopria_Alliance

(known as "IPP Everywhere" in the Linux universe)

As far as I know, AirPrint is a superset of IPP Everywhere, so most printers that support macOS/iPad/iOS will accidentally support printing on Linux too.

It makes sense, seeing that CUPS is used on all of them.
