Let us assume you intend to take advantage of the Citrix UPS/UPD functionality. The Citrix UPS server component is in place on your print server and the UPS client feature has been installed, enabled, and verified on the XenApp host as per the points I outlined in article CTX134913. You now want to test if all works as expected. Here is a quick way of doing that outside of an ICA session:
When logged in to the local server console of the XenApp server, navigate to your UPS-enabled print server (\\print server name), right-click on a printer and select connect. Next, open the server Devices and Printers window and select the connected printer. With UPS/UPD enabled, you should see the printer with Citrix Universal Printer specified in its model description.

Thanks for reviewing my post.
Have a great Citrix day,
