Or, are you being prompted for WPS PIN to connect a computer to a printer?
If you are being prompted for a WPS PIN to connect your computer to a printer, then follow the instructions HP Printers - Wi-Fi Direct Printers Setup. Wi-Fi Direct is a printing-only connection option you can set up directly through your HP printer rather than through a local Wi-Fi network router.
If you are unable to get setup your printer with either type of WPS setup, then you can use HP’s Wireless Setup Wizard or USB setup of wireless. HP’s Wireless Printing site also a great resource additional information.
