How do I switch the HP Photosmart 5520 from a USB connection to a wireless network connection on Windows?

On your computer, click Start > All Programs > HP > HP Photosmart 5520 series > Printer Setup & Software, then click 'Convert a USB connected printer to wireless.' Keep the USB cable connected until prompted to disconnect it, then follow the on-screen instructions. On Mac, touch the Wireless button on the printer's control panel, then use the Wireless Setup Wizard to complete the connection. (Page 4)
