samba - Sep 2002 - Advanced tab of printer properties, w2k to samba 2.2.6pre

Using samba 2.2.6pre (and earlier versions), I notice some of my changes 
from w2k client using printer properties do not persist.  For example, 
under the Advanced tab, disabling advanced printing features or changing 
how the printer spools, etc, appears to work until you close and reopen 
the printer properties, and you see the options are back to the 
original.  Am I doing something wrong, or are these features not supported?
