"BrowseAllow" lines describe which remote CUPS servers's printers this one will show in his own list of printers...

BrowseAllow is important for CUPS clients (more than it is for CUPS servers).

Your CUPS clients' cupsd.conf probably miss the correct "BrowseAllow" lines. Try this on your satellites:

  BrowseOrder Deny,Allow
  BrowseDeny All
  BrowseAllow 172.16.21.1

and you should be running...
