If you use BrowsePoll and BrowseRelay on a few of the CUPS clients,
it will use the standard CUPS "store and forward" mechanism.

On a few of the CUPS clients (ones that aren't turned off regularly),
add the following to their cupsd.conf files:

     BrowsePoll cups-master-server-1
     BrowsePoll cups-master-server-2
     BrowseRelay 127.0.0.1 local-subnet-broadcast-address

where "local-subnet-broadcast-address" is the broadcast address on
the client network.
