It's not. Mac is known for ease of set up. Not with this machine. Will try to talk to Brother support tomorrow but as of now, I'm not impressed. Should not be this difficult.
Writing about the slightly older but similar 2170. Has worked very well, we've been quite pleased with it. Wireless setup was not difficult, print quality excellent. Not the fastest printer in the world, and a little on the noisy side. Be aware that the 'low toner detecting' feature is actually quite pessimistic and will begin nagging you and finally declare the cartridge 'out' when there's still a good bit of life left in it. To get maximum use out of your cartridges, it's easy to disable this feature simply by putting a piece of masking tap over one of the sensor ports at either end of the cartridge.
Great printer -- great value. Easy to use and great printing quality. The wireless printing is difficult to setup -- but their telephone support helps. Once done -- we love it!
