HP Web Jetadmin - Discovering PC-Connected Devices

7
labeled WMI Credentials is checked
(Figure 2). The credentials entered must
be a member of the administrator’s group
on any workstation in order for HP Web
Jetadmin to perform WMI calls to
discover PC-connected devices.
Printers discovered using either proxy
agent are displayed in the All Devices list
as “PC Port” in the Port column (Figure
3). Devices discovered using WMI are
displayed in the All Devices list as “LPTx”
or “USBxxx” in the Port column. Multiple
devices attached to a single workstation
can be discovered. Each of the
multiplexed devices on a PC will have the
same IP address but different “Jetdirect
Port” numbers—similar to the behavior of
a multi-port HP Jetdirect EX print server.
NOTE: There are a handful of devices
that can be discovered by both the HP
SNMP Proxy Agent and the HP WS Pro
Proxy Agent. If both proxies are installed
and discovering one of these devices, if
the latest versions of the proxies installed,
the device will appear only once as being discovered by the WS Pro Proxy. If older versions of the
proxies are installed, the device will appear twice in the device list if found by both proxies. The
difference will be noted by the type of information that is displayed by each proxy (see Proxy
Comparison section later in this paper).
DEVICE MANAGEMENT
The proxies can provide the following types of functionality for discovered devices:
 Display device information such as status, supplies levels, page counts, etc.
 Configure specific features
 Monitor device alerts
 Generate reports
The level of support for each device will depend on the following variables:
 Which proxy discovered the device
 How the feature is exposed on the device
 How Web Jetadmin is defined to retrieve or configure the feature
Viewing device information
Selecting a device discovered by the proxies from 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 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 upon which proxy discovered the device and how
Web Jetadmin is defined to support the feature.
