printings

[Patrizia Canton]

I am feeeling quite stupid, but I am not able to have printers working.
I hope someone could help me.
I defined a print$ share 
set in the print$ share  write list= root 
and  printer admin=root 
when I connect from the WINNT client as root
I can see in the printer folder on Samba server
the printers I have in my printcap file
the print$ share,
but not the Add Printer Wizard.
If I try to view the printer properties for any printer
I can see that the "NEW Driver ..." button for installing the new printer
driver is not active.
so I am logging as root, but I am not root at all.
Why?
I am running Linux Debian2.2rev2, kernel 2.4.3
this is part of my smb.conf
