HP Web Jetadmin - Discovering PC-Connected Devices

enough SNMP. Use the same SNMP tool to determine if the machine with the proxy can walk the

PML MIB starting with the following OID:

.1.3.6.1.4.1.11

If the machine responds with answers to many OIDS, it is very likely that discovery should be

occurring successfully. If only a few OIDs respond, the problem is likely caused by the installed

printer/scanner driver does not expose the necessary device management interface (PML) to the

HP SNMP Proxy Agent.

12. Drivers are a common source of problems. Assuming the printer is supported but full SNMP

communication is failing, browse the registry on the desktop PC:

\HKEY_LOCAL_MACHINE\SOFTWARE\Hewlett-Packard\HP SNMP Proxy\PrnId

This entry records the name of the instrumented printer/scanner driver[s], if any. If the PC's

printer/scanner is supported, but the proxy can't instrument its driver, the PC will need a different

printer/scanner driver.
