contains an HP WS Pro Adapter that handles the

mappings between WS* and LEDM tickets. The

HP WS Pro Adapter service must be running on

the HP Web Jetadmin server to discover and

manage devices through HP WS Pro Proxy Agent.

HP WS Pro Proxy Agent is not a WS* proxy.

While LEDM and WS* devices share two

services—the WS-Discovery service and the WS-

Transfer device service—most traffic is different.

LEDM device management traffic is RESTful with a

URL for each ticket. WS-Management traffic is

SOAP-based with a URI for each service.

HP WS Pro Proxy Agent gains access to the USB-

connected printer through a component of the

Printer Driver known as UIO. The printer

information exposed to HP WS Pro Proxy Agent

via Web Services is plentiful, providing an

opportunity for strong management capabilities of

these devices.

DISCOVERY

HP Web Jetadmin can perform discoveries for

either networked devices or PC-connected

devices. A discovery for PC-connected devices

always begins by scanning the network to find

active nodes. An active node is any networked

device that responds to the discovery method that

HP Web Jetadmin uses. Figure 1 shows the

supported discovery methods that can be used to

locate nodes containing locally connected

devices. The following are the most common

techniques:

• IP range—Sends SNMP query packets to all addresses in the specified IP address ranges of.

• Specified address—Sends SNMP query packets to only the IP addresses specified in the list.

Note Quick Device Discovery on the main HP Web Jetadmin page is not supported for discovering

PC-connected devices. Quick Device Discovery is intended to find only network-connected

devices. PC-connected discoveries require a different technique than network-connected

discoveries. Quick Device Discovery cannot discard workstations. Quick Device Discovery

must continue probing to determine if a proxy is installed and which port on the workstation

contains a printer.

Remember, HP Web Jetadmin queries workstations instead of devices, so take care to ensure that

accurate ranges or lists of IP addresses are defined.

After the node portion of the discovery is complete, HP Web Jetadmin begins a resolution process to

qualify either PC-connected devices or network-connected devices. HP Web Jetadmin interrogates

each node with SNMP queries to determine if the node has any proxy agents installed.

If it is determined that HP WS Pro Proxy Agent is installed, HP Web Jetadmin attempts to talk to any

USB-connected devices through the HP WS Pro Proxy Agent service that was installed when the proxy

was installed. All the calls to the USB devices are routed through the HP Web WS Pro Adaptor
