What about "lpstat -p" on bumby2?

Yeah, they should show up under the Default pane.

Make sure the Mac system's /etc/cups/cupsd.conf file contains:

    Browsing On
    BrowseRemoteProtocols CUPS
    BrowseOrder allow,deny
    BrowseAllow @LOCAL

Also, make sure that cupsd is running:

    ps ax | grep cupsd

If it isn't, you'll never see the shared printers show up.

For CUPS shared printers, the drivers are all on the server and the client just grabs the PPD file to display the driver options.  All conversion/processing happens on the server.
