How do I switch the printer from a USB connection to a wireless connection on Windows?
Open the printer software, click 'Utilities,' then select 'Printer Setup & Software.' Choose the option to convert a USB-connected printer to a wireless connection and follow the on-screen instructions. On Mac, use the HP Utility located in the Applications/Hewlett-Packard folder to change the software connection to wireless. (Page 5)
