XenApp 6.x Session Printer creation is SLOW

I have the following issue on a Windows 2008 R2 Server with Xenapp 6 or
6.5

If I assign session printers to the users it tooks 10 to 20 seconds
per printer if the printer is connected.

I noticed that if I manually
install printers on one of the Citrix servers by browsing to the
printserver and double clicking on the shared printer, it says
"downloading driver" for each printer I install,
even if the printer being installed uses a driver that has already been
installed.I compared this to our old 2003 environment,
and connectingto a shared printer that uses a driver that is already
installed is instantaneous.

can someone help me?

Best Regards,
