Accessing the control panel from a computer
You can also access the printer control panel from a computer by using the HP toolbox or the Settings page of the embedded Web server.
The computer shows information similar to what the control panel shows. From your computer, you can also perform control panel functions, such as checking supplies status, viewing messages, or changing tray configuration. For more information, see Using the HP toolbox or Using the embedded Web server (HP Color LaserJet 3700 series printer only).
