Interestingly there is /etc/cups/printers.conf and /etc/cups/printers.conf.0

Both define both printers that I can see with my notebook browser 
pointed to port 631 on the server.  But when I use system-config-printer 
on my notebook to connect to the server, it only shows the printer I 
added using system-config-printer (note the other printer was first 
added via the web interface).  The question is why?  Here is the conf file:

# Printer configuration file for CUPS v1.7.5

It is TerminalRoom-8610 that only shows in the web interface.

Oh, both setups are for the same printer as you can see by the URI.
