I think, you should rename this file to "/etc/cups/client.conf" - that's
what it is called on my machines;-)

Yes, I think with your configuration it should...

Two times: No ;-)

Well, there are 3 possibilites:

1) You install on the client a full cups-server. Then - if you activate
   Browsing - your client will automagically know about all cups-Servers
   in the Network - and at the same time about all printers which are
   available. 

2) You install on the client a full cups-server. Then, on the client,
   using either the web-interface (localhost:631) or the
   commandline-interface (lpadmin) you add all printers which you want
   to use. Then, Browsing is needed to automagically detect additional
   servers in the network or newly connected printers - those printers,
   which you added "by hand" are independent of browsing.

3) you install on the client only the cups-client, and add in the file
   /etc/cups/client.conf (It is "client.conf", NOT "cups.conf"!!!!!!!)
   the parameter "ServerName haggis". With that, the client will ONLY
   use this cups-Server - and whenever the client wants to know
   something (what printers do exists, are the working, paper jam, ...),
   the client will ask the server. So: in this configuration, it is
   irrelevant whether Browsing is activated or not... The cups-client
   packages do NOT contain a daemon which listens all the time:-)

However, always important are of course the access rights on the server;
and you have to "share" the printers on the server - in order to allow
clients to use them...


HTH,
