What is the default security setting for Wi-Fi Direct on this printer?
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. (Page 2)
