How do I change my printer connection from USB to wireless?

On Windows, click Start > All Programs > HP > HP Photosmart 6520 series > Printer Setup & Software, then select 'Convert a USB connected printer to wireless' and keep the USB cable connected until prompted to disconnect it. On Mac, touch the Wireless button on your printer's control panel, touch Wireless Setup Wizard, follow the steps to connect, and then use HP Setup Assistant in Applications/Hewlett-Packard/Device Utilities to change the software connection to wireless.
