I HIGHLY recommend the HP Photosmart C7280.
I have one and it does indeed do WPA2. It's a fax, scanner and copier all in one.
The thing I love about this printer is the HP 02 ink system. On the black cartridge I get a little over 700 pages per black cartridge before having to change it out. At 20 bucks a cartridge, that's a pretty good deal. They also have a pack that contains all six colors + 150 sheets of photo paper for $36. There is not as much ink in this pack though, it is formulated for 150 photos.
It's a tad on the expensive side. $300 retail. You can usually find it on sale somewhere for 260-270. If you have a Costco/Sam's membership, the Photosmart C7250 is the exact same printer, just renamed so that stores won't have to pricematch to a warehouse club (like they do anyways), for $250. If you know an employee at a Sams, I know they get the C7250 for $220.
You might also try Office Depot. Sometimes they carry refurbished HP printers. My current printer isn't a C7280, but a C6180. The only difference between the C7280/50 and the C6180 is a duplexer (optional on the 6180, included in the 7280/50). I got the 6180 refurbished for myself for $200 and the 7250 for my inlaws for $220 from a Sam's employee.
If you don't need wireless, the Photosmart C6280 is the same thing - wireless, duplexer and fax. The C6280 has ethernet and sells for about $160 usually. A lot of people think that if they have a computer on wireless, like a laptop, that they HAVE to buy a wireless printer. Working at BB this fall that was the number one misconception I ran in to. If you have your printer next to your router there's absolutely no need for a wireless printer. The wireless is only needed if you position your printer away from your router, like in another room or something.
Disclaimer: I worked over the fall and christmas as a HP Retail Rep going in to stores like CC and BB and helping them pawn HP Printers/Computers... Fell in love with that printer during training meetings.
