How do I convert my HP Envy 4500 from a USB connection to a wireless connection on Windows?

On Windows, navigate to All Programs, select HP, then HP ENVY 4500 series, then Printer Setup & Software, and finally select 'Convert a USB connected printer to wireless' and follow the on-screen instructions. On a Mac, use the HP Setup Assistant found in Applications/Hewlett-Packard/Device Utilities. You must have already successfully installed the printer software before attempting this. (Page 5)
