HP Web Jetadmin - Supported Printer Features in HP Web Jetadmin

displaying a better bitmap but claims Credential Failure for status, an EWS password has been set on
the device and Web Jetadmin does not know it.
Notice how the front panel display still claims <Not Supported> and only the Trays gauges are
present. In this scenario, right-click the device and select Update Credentials. If the EWS password is
known, enter the user name and password and set it for the device. Click on another device and back
to the original device to see full support. Web Jetadmin will tuck away the EWS password to be used
for all subsequent attempts to read or write information to the device.
If the EWS password is unknown, it is still possible to read minimal information from the device using
a Guest account, just as EWS does to display the Information tab when an EWS password is set.
Merely follow the instructions above for entering the EWS password into Web Jetadmin, but enter
“guest” as user name and a blank password. Web Jetadmin should now have enough credentials to
at least display proper supplies gauges and front panel message.
Of course, if it is desired to perform configurations, the EWS password will have to be entered into
Web Jetadmin as the Guest account does not provide enough permission.
DEVICE CONFIGURATION
Many device settings can be viewed and configured through HP Web Jetadmin. Device configuration
works differently depending on whether a single device or multiple devices are selected. If a single
device is selected from the device list, the configuration items in the Config tab are shown with the
current device settings.
