I have a Brother HL-4040cn Color Laser connected to my switch. Works great for household printing (book reports, recipes, text, basic color etc.) Brother discounted them $200 over the holidays, so I got it for $200 from Officemax.
I also just ran out of ink on my Epson R380 which was nice, but had to use a wireless print server from linksys (flakey), so I spent a few extra dollars and upgraded to a Canon Pixma MP620. The 620 has built-in wireless. It took me about 15 minutes from opening the box to working on both Macbooks. The Canon software works great. You can scan from the printer to the Mac or from the application on the Mac. One of the things that pushed me over the edge on this printer are the $14.00 replacement cartridges.
Both of these printers work via networking on the Mac and they setup very easy.
