IP Hostname is an element that is populated with a name retrieved from network DNS (Domain Name Service).
HP Web Jetadmin uses the device IP address and performs what is known as a reverse-lookup; DNS responds
with a name value if one is registered within the service for that particular IP address. Two requirements exist for
HP Web Jetadmin to be able to get a device's IP Hostname: DNS provides reverse name lookup based on the IP
address, and the device IP address must have a name registered in DNS. If HP Web Jetadmin performs a name
lookup for a device’s IP address and DNS is unable to deliver a result, the value Unknown is displayed in the
device list's IP Hostname column. HP Web Jetadmin will only show resolvable names in the IP Hostname column.
The IP Hostname column is enabled by default. To populate this column, HP Web Jetadmin must perform DNS
lookups. To enable DNS lookups, go to Tools > Options > Shared > Network > DNS. For security and performance
reasons, you can disable DNS lookups.
System Name is an object that is bound to the HP Jetdirect print server. The System Name appears as Host
Name in the Embedded Web Server (EWS) interfaces for many devices in the networking conguration area. This
device bound name, in and of itself, is not resolvable through DNS. When a device’s System Name is changed to
something like “PRTR445” and the DNS name value for a device’s IP address is “lab412”, the IP Hostname
column in HP Web Jetadmin will reect “lab412”. System Name is simply a device bound object that can be
changed using HP Web Jetadmin and the device’s EWS but there are cases when it can also be registered into
DNS.
HP Jetdirect print servers have a few dierent features that can allow the System Name value to become
registered into a device’s DNS. In many cases, when devices have their IP address parameters DHCP congured, a
registration with DNS is possible. This is dependant on both the DHCP system on the network, the HP Jetdirect
print server model and rmware revision, and the system name being populated on the HP Jetdirect print server.
For more information about DHCP/DNS name registration, see the technical documentation for HP Jetdirect print
servers. WINS is another network service that can be used to make HP Jetdirect print server system names
visible through DNS. Many HP Jetdirect print servers are capable of exposing the System Name via WINS and
WINS/DNS linkages can cause these names to be DNS visible and also appear in the IP Hostname column in
HP Web Jetadmin. For more information about IP Hostname and DNS registration, see the technical
documentation for HP Jetdirect print servers.
Statuses on Device Lists in HP Web Jetadmin
You can select columns to view on Device Lists from a static list of columns. The various statuses might be
displayed in those columns include:
●
Unavailable: The device does not support the column.
●
Undened: For the HP Jetdirect version when the device is incapable of reporting that attribute.
●
Missing: Usually a temporary status until the device communicates its data to HP Web Jetadmin.
Manipulating Columns in Device Lists
You can manipulate columns on the device lists in HP Web Jetadmin:
●
Selecting Devices: Selecting a device means performing some action that causes the device to become
selected which sets up the device or devices for some further action. Click to select one device or Shift
+Click to select multiple devices.
●
Resize columns: To set the width of a column, click and drag the column marker in the list header to the
desired width. Or, to resize the column to the broadest width required to display the data, double-click on
the column header.
●
