Amazed with Samsung!
Now, its not a 100 pound printer, slightly more expensive, but 1.5 / 2 years ago I got myself a multi-purpose Samsung SCX-4623 printer (laserprinter, scanner, copier and fax). First because I could get it fairly cheap, and second because this one fully supported networking.
Linux (CUPS) has always given me nothing but trouble with this one, but on Windows everything just works great. Quite frankly, its been almost 2 years now and its still going strong. Its very easy for a small office to have such a critter ready for work, but without the need to put it on your desk or table. It simply sits in the further side of the room.
Before I had this one I always figured Samsung to be good for phones, but that's it. Well, I had to re-adjust that idea a little ;-)
