Use the following steps to execute the UIO test tool:
1. Double-click the UIOTest.exe le. This le is located in the HPWSProxy\bin\ directory.
2. From the Select Printer list, select the USB-connected printer. This list includes the printers that were
previously connected, but are now disconnected. This list is the same as the list shown in Control Panel >
Hardware and Sound > Devices and Printers.
3. Select a printer type: FuturesSmart, or LEDM for non-FutureSmart devices. For FutureSmart devices, skip
to step 6. For LEDM devices, continue to step 4.
4. From the Select LEDM Tree list, select a tree element.
5. Click the Get On All the Trees or Get On A Selected Tree button.
6. Select a Service Urn from the drop down menu.
NOTE: The drop down menu might show elements that are not supported or available on the device, such
as /copy which is not available on a single function device.
7. Click Get.
The results are written in the UIOLog.txt le. This le is in the same directory as the UIOTest.exe le. Prior to
HP WS Pro Proxy Agent 10.3.8, this le was created in the C:\temp directory. For HP WS Pro Proxy Agent 10.4.1
and later, the results are also written in the display pane.
The following are examples of log entries:
Time:24/06/2016 11:11:08, The tree is: /DevMgmt/MediaHandlingDyn.xml
And The Response is null
Time:24/06/2016 11:09:26, The tree is: /DevMgmt/DiscoveryTree.xml
And The Response Status Code is : 200
Time:24/06/2016 11:09:33, The tree is: /TestNode/ExpectFailure And
The Response Status Code is : 404
Response Status Code null means: printer is connected
Response Status Code 200 means: printer is responding correctly
Response Status Code 404 means: endpoint not existing (while printer is
connected)
Other Response Status Code might be different per device model.
Congure the HP WS Pro Proxy Agent service behind a rewall
For the HP WS Pro Proxy Agent service to work behind a rewall, you must add the proxy service and/or the
ports the proxy service uses to the rewall exception list. The proxy service uses two TCP ports for HTTP or
HTTPS communication with HP Web Jetadmin and one UDP port for discovery.
NOTE: At this time, the two TCP ports are dynamic. The HP WS Pro Proxy Agent service requests the two TCP
ports on the rst startup.
To add the proxy service and its ports to the rewall exception list, perform the following steps:
1. Add the HPDeviceProxyService.exe le from the proxy installation directory to the rewall exception list.
The HPDeviceProxyService.exe le is located in one of the following directories:
●
For a default installation on a 32-bit operating system:
C:\Program Files\HP Inc\HPWSProxy\bin\
●
For a default installation on a 64-bit operating system:
