• WJADISCOVERYPORT

This parameter specifies the port where HPWSProxyService sends WS Probe ‘Hello’ packets. This

port must be in sync with the port that HP Web Jetadmin is configured to listen on for PC-connect

WS hello messages.

default value: 27893

• LEDMDISCOVERYPORT

This parameter specifies the port that HPWSProxyService listens on for discovery probe requests

Note that this is the UDP port. This port must be in sync with the port where HP Web Jetadmin is

configured to send PC-connect WS probes.

default value: 27893

The following is an examples of the command-line command:

msiexec /i HPWSProxyService.msi WJAHOSTIP=1.2.3.4

WJADISCOVERYPORT=27893 LEDMDISCOVERYPORT=27893

HP SNMP Proxy Agent

HP SNMP Proxy Agent implements its service as an Extension Agent within the framework provided

by Microsoft SNMP Service for Windows. Therefore, HP SNMP Proxy Agent requires that Microsoft

SNMP Service already be installed. The proxy uses a redirector to multiplex multiple devices through

a single host IP address.

The proxy’s extension agent implements the following SNMP MIBs:

• HP proprietary Printer Management Language (PML) MIB.

• Standard Printer (STD) MIB

• HP Jetdirect (NP) MIB beneath the HP Enterprise MIB

• HP SNMP Proxy Agent MIB beneath the HP Enterprise MIB

The Microsoft SNMP Service component for Windows implements the following MIBs:

• MIB-II

• Host Resource (HR) MIB

Microsoft organizes the hrDeviceStatus, hrPrinterStatus and hrPrinterDetectedErrorState tables

differently than HP Jetdirect. Because these tables include many devices (such as mice, CD/ROMs,

keyboards, and disks) as well as zero or one or more printers, HP Web Jetadmin uses the proxy’s

redirector for accessing the device’s host resource MIB.

Unredirected queries about the network interface (IP address, subnet mask, and so on) query the

corresponding tables in the Windows Workstation, not the device (even if the device is also

networked). To access MIB-II in the device, HP Web Jetadmin must use the redirector.

HP WS Pro Proxy Agent

Newer HP devices support management protocols more advanced than SNMP that use Web

Services, namely WS* and LEDM. HP WS Pro Proxy Agent was developed to support LEDM printers

that do not support enough of SNMP for HP SNMP Proxy Agent to provide the desired management.

HP WS Pro Proxy Agent resides on a PC workstation and replicates a device’s services from the host

computer’s USB interface to its network interface. HP SNMP Proxy Agent runs as a Network Service

when installed on workstations and is developed using WCF 4.0 to leverage the WS-Discovery

feature. Microsoft .NET Framework 4.0 is required for installation. Each HP Web Jetadmin installation
