If you're on CUPS 1.2.x, look at

   http://localhost:631/help/ref-cupsd-conf.html?TOPIC=References

If you're on CUPS 1.1.x, look at

   http://localhost:631/sam.html

Search for the keywords "BrowsePoll" and "BrowseRelay"

You have different options:

  a) let each of the machines in the different subnet do "BrowsePoll"
     for itself. Puts additional load on the CUPS server for each 
     separate client polling

  b) let one or few clients in the subnet do "BrowsePoll" and at the
     same time "BrowseRelay" to their own subnet. Requires these 
     clients to be more or less continuously up.

Example for client whose assumed IP address is 10.162.0.56/255.255.255.0
polling CUPS server 192.168.34.56

  BrowsePoll 192.168.34.56:631
  BrowseRelay 127.0.0.1 10.162.0.255

All clients on net 10.162.0.[1-254] should see and be able to use all
printers now (if the CUPS server accepts the clients, that is...)

Cheers,
