    From a glance, I can suspect two things I'd check first...

1. Check your firewall to see if port 631 or whatever port you are using
   cups is open on your print server

2. Check to see if  your cupsd.conf is only willing to
accept jobs from the machine connected to the printer directly but not
remote machines.  You might want to muck with /etc/cups/cups.conf or
wherever it is stored on your system and check for something like...

<Location />
Order Deny,Allow
Deny From All
Allow From @LOCAL
</Location>

    If you're missing the Allow from @LOCAL or something similar 
I believe cups will just deny access to it.

    D'oh.  I hate when this happens.  It's always a good reminder to
remember to copy your working configs into a save directory to use as a later
reference when something breaks (again).
    Or use RCS|svn|git|cvs|my-favorite-tool and enjoy the power of
version control
