Revision history (partial)

HP SNMP Proxy Agent is installed on a desktop client PC. HP Web Jetadmin uses HP SNMP Proxy Agent to

discover and manage HP printers and scanners that are connected locally (for example, through a USB

connection). HP SNMP Proxy Agent exposes management objects through the Microsoft SNMP service on the

client PC. In HP Web Jetadmin, a simple PC-connected discovery nds the locally attached devices.

HP Web Jetadmin can then gather additional device information—such as remaining toner levels, page counts,

and status—through the proxy.

Features

HP SNMP Proxy Agent includes the following functionality:

●

HP Web Jetadmin queries the HP-proprietary and standard management objects in the supported devices.

Dierent devices oer varying levels of support, but many devices expose the model name, engine page

count, supplies levels, serial number, and so on.

●

HP Web Jetadmin supports reading and writing information on PC-connected devices.

●

HP Web Jetadmin detects status changes in a PC-connected device by polling or manually refreshing the

device. HP Web Jetadmin does not support traps for PC-connected devices.

●

A discovery must complete successfully before a PC-connected device is available in HP Web Jetadmin.

●

HP SNMP Proxy Agent and HP Web Jetadmin support multiple PC-connected devices (for example, through

a USB connection) on a single desktop client PC.

●

HP SNMP Proxy Agent adds support for some HP Ocejet Pro devices through the HP Ocejet Basic Driver

- IT Professional Use Only driver package.

●

HP Web Jetadmin can perform a PC-connected discovery by using the IP broadcast method.

HP Web Jetadmin uses an SNMP query for the IP broadcast packet. However, this discovery method yields

limited results because some systems and many networks block IP broadcast trac for security and overall

management reasons. The workstation or server that HP Web Jetadmin sends the IP broadcast to must

have an SNMP service that responds to these packets. For a comprehensive and scaled discovery plan,

HP recommends that you also use other discovery methods, such as IP range and Specied addresses.
