I see this at the end of my cupsd.conf file

<Location /printers/stylus-photo-r300--1>
Order Deny,Allow
Deny From All
Allow From 127.0.0.1
AuthType None
</Location>
Browsing On
BrowseProtocols cups
BrowseOrder Deny,Allow
BrowseAllow from @LOCAL
BrowseAddress 255.255.255.255
Listen *:631

Similar <Location> stanzas for *some* of the printers I have defined,
but not all.
It seems it has all the lines you suggested Paul, but the location
blocks likely prevent the connection.

My questions now become this:
1. Why does it only show some of the defined printers?
All were defined using the cups interface. The ones listed in cupsd.conf
and those not listed there all work from the local print server.

2.  This area is clearly marked with a line that says 
# Lines below are automatically generated - DO NOT EDIT
What happens if I do edit that part of the file, then maybe change or
add printers after editing it?


I would think that the use of the cups interface to define printers
would be standard, but it was not.  I also cannot find in any of
the /admin pages a way to turn on sharing so it seems this would have to
be edited in order to enable sharing.

I guess the admin of cups is a bit obscure on how to do things other
than printing on the localhost.

I will try a couple of other things and see what the result is.

Thanks for the pointers.
