Network printer driver re-installed at each logon with RDS

Using Server 2008 R2 SP1 with RDS enabled for shared Desktops. Network printer are mapped during logon on a per user basis via script. At logoff all network printers are disconnected in case users get a new set of network printers. Every time a users logon ALL network printers are re-installed and takes quite some time for a buch of printers. The same happens using group policy or with Rundll32 printui.dll,PrintUIEntry and the option /u (do not install if available).

That has two negative effects, one it slows down logon time and uses quite some CPU. Around 70% per 3rd party printer driver for up to 9-20 seconds. On an RDS Server that can have some unnecessary impact on other working users.

So is there any way to change the behaviour to not install printer drivers over and over again per user on a enabled Remote Desktop Server at logon?
