HP SNMP Proxy Agent

HP SNMP Proxy Agent supports a wide variety of SNMP-capable HP devices that are directly

connected to client machines and meet the following criteria:

• The Windows SNMP service must be installed and configured to allow queries from the HP Web

Jetadmin server. The community name should be set to public for read access.

• Firewall settings must be appropriately modified to allow HP Web Jetadmin to query HP SNMP

Proxy Agent. This means that UDP port 161 should be open for SNMP queries.

• Printers must be installed using a DOT4 bi-directional capable driver or a driver containing a

special language monitor in order to respond to SNMP queries

For directly connected devices to be discovered via HP SNMP Proxy Agent, proper communication

between the device and client machine must be provided. For devices that support DOT4, use a

driver that provides an HP DOT4 port connection, whether the connection is via USB or LPT. An

example of the correct port type is DOT4_001. If the port type is different (for instance, LPT1 or

USB001), the following options can provide a proper DOT4-capable driver:

• Use HP Universal Print Driver (UPD) version 4.5 or later.

• When using HP Universal Print Driver (UPD) 6.1 or later, HP SNMP Proxy 10.4 or later is

required.

• Use the HP printing system software CD that came with the device to install the HP DOT4 port.

• If the printing system software CD is not available, download the latest printing system software

from www.hp.com

Composite USB devices that do not support DOT4, such as the HP LaserJet P2055 printer, require a

language monitor that is capable of passing PML over Printer Job Language (PJL). HP UPD 4.7 added

support for composite USB devices.

A complete list of printers supported by UPD can be found on the HP UPD website. For a complete list

of tested devices, see “Appendix A—Supported printing devices” on page 26. Items in yellow

indicate LEDM devices that provide very little information if HP SNMP Proxy Agent discovers them.

Items in red indicate HP FutureSmart devices that provide nothing more than the model name using

HP SNMP Proxy Agent.

HP WS Pro Proxy Agent

HP WS Pro Proxy Agent requires that .NET Framework 4.0 be installed. HP WS Pro Proxy Agent

installs as its own service and does not require the Microsoft SNMP service to be installed. This proxy

discovers devices that support LEDM, which is a special form of Web Services for communication.

For a complete list of tested and supported devices, see “Appendix A—Supported printing devices”

on page 26.
