1 Proxy agents
NOTE: The most current version of this Readme is available from the HP Web Jetadmin support page (in
English).
A proxy agent is client-side software that allows HP Web Jetadmin to discover and manage devices that are
connected directly to the network. The proxy agent is capable of passing the same types of queries to PC-
connected devices that are typically passed to network-connected devices. Therefore, HP Web Jetadmin can
gather additional device information about PC-connected devices, such as remaining toner levels, page counts,
and status.
HP provides the following proxy agents:
●
HP SNMP Proxy Agent works by exposing object identiers (OIDs) in the printer management information
base (MIB) to the Microsoft® SNMP service that runs on the host PC where the device is connected through
a USB port.
●
HP WS Pro Proxy Agent is a Web service that runs under the network service account on a PC workstation
and replicates a device's services from the host computer's USB interface to its network interface.
While most devices support HP SNMP Proxy Agent, a few devices require HP WS Pro Proxy Agent.
The HP Proxy Agents package includes the following:
●
HP SNMP Proxy Agent—Separate MSI installers for the 32-bit and 64-bit operating systems
●
HP WS Pro Proxy Agent—A single EXE installer for both the 32-bit and 64-bit operating systems
To download the HP Proxy Agents package, go to www.hp.com/go/webjetadmin, click Download now, and then
follow the instructions.
As a general rule, you should install both HP SNMP Proxy Agent and HP WS Pro Proxy Agent. However, be aware
that there are a few devices that HP Web Jetadmin can discover through both HP SNMP Proxy Agent and HP WS
Pro Proxy Agent. If you install both proxy agents on a machine where HP Web Jetadmin discovers one of these
devices, the device appears in the device list twice.
For more information about the proxy agents, see the Discovering PC-Connected Devices in HP Web Jetadmin
white paper. This white paper is available from the HP Web Jetadmin support page (in English).
