[K12OSN] Problems with samba printing 3.1.2

[Burke Almquist <balmquist mindphyre com>]

I noticed recently that I can still print through cups, however samba 
printing suddenly stopped working.  smb.conf attached
It looks ok to me, using samba 2.2.7a. and cups 1.1.17.
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options (perhaps too
# many!) most of which are not shown in this example
#
# Any line which starts with a ; (semi-colon) or a # (hash) 
# is a comment and is ignored. In this example we will use a #
# for commentry and a ; for parts of the config file that you
# may wish to enable
#
# NOTE: Whenever you modify this file you should run the command "testparm"
# to check that you have not made any basic syntactic errors.
