Can I use the printer without a router with Wi-Fi Direct?

Yes, you can use the printer wirelessly without a router by using Wi-Fi Direct. For more information on how to set this up, visit www.hp.com/go/wifidirectprinting. Note that the product is designed for use in open environments where anyone in wireless range can connect and access all functions and settings by default, but you can change the Wi-Fi Direct Connection Method from 'Automatic' to 'Manual' and establish an administrator password for higher security levels if desired.
