I believe the control panel options could be controlled (enabled or disabled) through the device's web console (EWS Page).
Just access the HP 9250C from a web browser using its IP address or hostname & go to Settings TAB
Select the option "Home Screen Setup" from the options displayed on left side of page & Check Mark (Show) the Administration button.
Hope this help!
