When i try add a Xerox printer, through a Xenapp 6 Citrix printer policy (session printer policy), we receive the following error: "An item with the same key has already been added".
We are using a Windows 2003R2 32Bit print server, with a Xerox C3545. The x64 5.185.15 drivers are installed on the print server (additional drivers option) Tried PCL 5 and 6
We do not have this problem with Cannon or HP drivers
The fix is available from Citrix web site.
Tested in my lab.(it's not a production environment)
Now, there is no error message when I load a xerox printer driver through Citrix policy.
Hope this will help you
