A good affordable WLAN printer

I give up,

I have 4 "All-in-One" printers standing here. One from Canon, three from HP. All of them FAIL to deliver when it comes to wireless printing. Heck, I'm even stuck in the installation, tried all kinds of firmware and browsing dozens of forums. What kind of WLAN printer do you have/recommend?

My failed printers:

-Canon Pixma MX410

-HP DeskJet 5150

-HP Photosmart 5275

-and the worst of them all: HP PSC 1210

Running Windows 7 64 bit
