Native means comes with the system. If you have to download it separately, it isn't native. It used to mean built in and operating without translation layers, but modern software is generally built with layers on layers from the get-go so that's no longer a meaningful distinction.
Windows' support for basic VGA mode does not constitute meaningful support for GPUs which have not been released because you can use almost none of the functionality. So sure, it "supports" them... but only well enough to download a driver for actual support. Anything supported for more than the most trivial mode actually is supported with a driver more complex than Standard VGA already included in the system.
"Linux" does not have printing support, it has support for the technologies needed to connect to a printer. "<x distribution> Linux" has printing support.
