[Samba] Solaris printing: what kind?

[need2know]

I have Samba 3.0.11 running on a Solaris 7 system.  File sharing
is okay so far, but I'm having some issues with printing.  The
first thing I really need to do is determine what kind of printing
to put into smb.conf.  I'm sure it isn't cups, but without much
background in printer administration, I don't know what files or
daemons or settings to look for to figure out what's actually
running now.  Could someone please provide clues, or a pointer to
some documentation?  Thanks.
