samba - Mar 2010 - 3.5.0 mixture of print clients xp and x64

Hi,

just for my understanding, is it possible by design to mix drivers for x64 
(windows 7 64 bit) and xp printing on one samba server?

I have the xp driver installed and everything is running fine. Using the 
printer management console on a windows 7 machine I am able to install 
64bit win 7 driver on the same samba server, they go into the dir 'x64'
as
expected.
