• To check the status of Wi-Fi Direct, as well as the Wi-Fi Direct network name and password, from the printer

• To learn about how to print with Wi-Fi Direct, visit the Wi-Fi Direct Printing website at
www.hp.com/go/wifidirectprinting.
Note: Wi-Fi Direct connection does not provide Internet access.
This product is designed for use in open environments (e.g., in homes and not connected to the public Internet) in
which anyone may access and use the printer. As a result, the Wi-Fi Direct setting is in "Automatic" mode by default,
without an administrator password, which allows anyone in wireless range to connect and access all functions and
settings of the printer. If higher security levels are desired, HP recommends changing the Wi-Fi Direct Connection
Method from "Automatic" to "Manual" and establishing an administrator password. You can change the security
settings from the embedded web server (EWS). For help on EWS, refer to the user guide on
www.hp.com/support/ENVY7800 or the electronic Help.

Basic troubleshooting
