Important Notes about This Release

• This is the server component of the Citrix Universal Print feature. Install this component on each print server that provisions session network printers and that uses the Universal Printer Driver for the session printers (regardless of whether or not the session printers are centrally provisioned). Do not install the server component on a server that has XenApp or XenDesktop installed. If you attempt to do so, the installation might fail and render the server installation unstable.

5. The Citrix XTE Server might exit unexpectedly or fail to process Universal Print Client requests. The issue occurs as a result of incorrectly set thread values.

   • Default value of 5000 for the HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\XTEConfig\MaxThreads registry value.
   • Minimum value of 150 for the HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\XTEConfig\MaxThreads registry value.
   • Default value of 8000 for the HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\XTEConfig\ThreadLimit registry value.
   • Minimum value of 150 for the HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\XTEConfig\ThreadLimit registry value.

   [From UpsServer710WX86100][#LC0007]

6. A high number of concurrent print requests from multiple sessions can render the print server unresponsive.
