samba - Mar 2009 - slow printing vista

Hi,

We are running samba Version 3.0.28-1.el5_2.1

The directory shares are working well.

But we are experiencing slowness when connecting and talking to the 
printers.
Has anyone any ideas about why this could be happening and how to fix it?

For windows XP we solved this problem by deleting registry entrys in

HKEY_CURRENT_USER\Printers\DevModePerUser

HKEY_CURRENT_USER\Printers\DevModes2

But that doesn't work for vista?


Our config file:

# Global parameters
[global]
        workgroup = APSS
        netbios name = APSS
        server string = APSS Samba
