I received this printer today, and straight out the box it seemed really easy to setup.
The wifi part was very easy to setup, just followed the instructions in booklet and no problems at all.
For those using windows vista sp1 or sp2, you might run into a driver problem.
Just restart computer, keep hitting F8 till a menu appears.
Click on directory recovery, it basicly loads up vista with just the basic drivers needed to run.
Install from cd, then when it all finished, just shutdown and restart as normal, and all is fine.
I just mentioning it incase you get the error and think there something wrong.
So far print quality is excellent, and it letting me print addresses on envelopes with complete ease, Never known a printer to work so well, and be so easy to setup.
I would seriously recommend this printer.
