Ooops.. probably shouldn't have said that much... my point is that
Linux will work with the printer regardless of i/f.

With one machine acting as the print server and if cups broadcasting
is enabled, the other machine's cups will just see the printers.
Of course, that's when all are using cups.  You may have to create
a raw smb printer queue for your windows boxes.  If you go that route,
I recommend creating 2 queues for each printer, a raw one for
Windows clients and a non-raw one for your Linux boxes.  You'll
have to enable octet-stream printing in /etc/cups/mime.convs (it's
commented out by default) and /etc/cups/mime.types.

I'm sorry.. are you saying you get the error about not being
able to connect to hostname:631 when you print the test page??

This is fine, cups by default doesn't enable remote administration... just
localhost.  SUSE goes further by making you setup a admin user before
you can even do administration.

If the printing server box is "hostname" that when you would setup
to use ipp://hostname/printername... however, if the hosts are using
cups... and you broadcast the info, the queues will setup automatically.
You'll need seperate queues for smb (for your Windows clients)... or
you'll have to download the free MS software to enable ipp (this may
be included in XP now... not sure).
