Quick Device Discovery
If you know the IP address or hostname of a network-connected device, you can use the Quick Device Discovery
feature to nd the device instead of running a full network discovery. To use the IP hostname for the Quick
Device Discovery feature, DNS lookups must be enabled. For instructions on enabling DNS lookups, see
Congure the DNS Settings on page 47.
You can only use the Quick Device Discovery feature to nd PC-connected devices if the devices are already in the
HP Web Jetadmin database. To nd a PC-connected device that is not in the database, you must run a device
discovery and use the PC connected devices option. For more information about PC-connected device
discoveries, see PC-Connected Device Discoveries on page 137.
To nd a network-connected device, the Quick Device Discovery feature searches the device addresses in the
HP Web Jetadmin database. If the device address is in the database, HP Web Jetadmin highlights the device in
the All Devices list. If the device address is not in the database, HP Web Jetadmin performs a network query only
