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 finds 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. Different devices offer 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 Officejet Pro devices through the HP Officejet 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 traffic 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
Specified addresses.
