The level of support for each device depends on the following variables:
• Which proxy discovered the device
• How the feature is exposed on
the device
• How HP Web Jetadmin is
defined to retrieve or configure
the feature
View device information
Selecting a device that the proxies
discovered in the All Devices list
and selecting the Status tab
displays various device details
(Figure 4). Information such as IP
Address, IP Hostname, and
Hardware Address pertain to the client workstation where the device is connected. The remaining
details pertain to the device itself. A matching picture is displayed, including the real-time status of the
device. Supply level gauges apear as well as descriptive items, including Device Location and System
Contact. Again, all of this information depends on which proxy discovered the device and how HP
Web Jetadmin is defined to support the feature.
Additional information pertaining to the device can be obtained by adding any of the hundreds of
columns that are available. Items such as Device Firmware Version, Engine Cycle Count, Serial
Number, and Install Date can be viewed in columns, just for starters.
Note Firmware upgrades for USB-connected devices and HP SNMP Proxy Agent or HP WS Pro
Proxy Agent is not tested or supported.
If WMI discovered the device, no additional device information can be displayed on the Status tab
other than the model name. Additional information is not available in the registry. Only the proxy
agents can gather such information.
Set device configurations
Selecting a device that the proxy agents discovered in the All Devices list and selecting the Config tab
displays various configuration options (Figure 5). The ability to set configuration items for printers
discovered through HP SNMP Proxy Agent depends on the following factors:
• The SNMP service must be configured to allow for getting and setting information via SNMP.
Right-click SNMP Service, select the Security tab, and edit the public community name to allow for
READ WRITE community rights instead of the default value of READ ONLY (Figure 6).
• Only configuration items that use SNMP
Set Request packets to configure are
successful if discovered via HP SNMP
Proxy Agent. Other settings that require
HTTP packets to configure the device will
fail. HP SNMP Proxy Agent only knows
how to pass SNMP to the device.
• Only those SNMP configuration items
that use OIDs defined in the standard
printer MIB or the HP proprietary MIB
are successful when using HP SNMP Proxy Agent. Configuration items that use MIB-II or Host
