HP Web Jetadmin 10.3 - Proxy Agents Readme

1 Proxy agents
NOTE: The most current version of this Readme is available from the HP Support Center.
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 identifiers (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 MSI 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 Support Center.
