We bought a Brother a few years ago, because it supported Google Cloud Print. The idea was that my son, who used a Chromebook, would be able to easily print. The problem came when the GCP worked only for a limited time, and then stopped working a few weeks after we got the printer. I was able to set it up to work via a Linux machine and the "cloudprint" daemon, but this was supposed to be _EASY_ and it wasn't.
Assuming this was just a problem with GCP, I recommended a Brother to an Apple-using friend who was trying to decide between an HP and a Brother. She uses airprint (I'm not a Mac/iPhone person, so I never tried it). And she has the same problems with the printer just not being found as an airprint device.
