Got mine in today. Real easy setup - smart packaging that only takes a minute to unbox, then I just downloaded the latest driver (not the bundle) off Brother's website & set the software to duplex by default. It is a noisy laser, but not much louder than my Samsung or Konica lasers. Still makes my lights flicker like the others I have. Slightly larger footprint than the other lasers, but also shorter in height. Not as smelly as my other ones - the Konica especially made my room stink like burnt toner.
Prints REALLY fast. The auto-duplex feature is super nice - it prints it out about 3/4 of the way, sucks it back in, then spits it back out. It keeps the duplex printing rolling right along - I didn't know how long the duplex feature would take but it sucks it right back in and spits it right back out, so it's pretty dang quick. I printed out a small booklet front & back as a test - saves a LOT of paper. Thanks OP!
Make sure you get a USB cable if you're hooking up locally! (doesn't include one - hit up Monoprice if you need one cheap)
