Wel, im thinking, you can setup as following. 

in this order..

1) /srv/samba/printer_drivers
( something like ) 

chmod 2775 /srv
chmod 2775 /srv/samba
chmod 2775 /srv/samba/printer_drivers

2) setup the share from windows pc. add the 2 groups to the share with full access.  
	( share tab ) domain admins and a second global security. 

3) set the security rights from witin windows on the shared folder. 
	( security tab) domain admins and a second global security 

>.This means nobody can access it now. 
set "authenticated users to have read access on the share" if needed, 
the security rights will stop any folder access

and leave alone. :
