hi
yes.. I tried to change the BrowsePoll variable from "30" to "0" ...

and as it is mentioned in the System Administrators Manual:
" The BrowseInterval directive specifies the maximum amount of time 
between browsing updates. Specifying a value of 0 seconds disables 
outgoing browse updates but allows a server to receive printer 
information from other hosts."

BUT... doing a "ps -ef|grep cups"

root 24874     1 10 11:27 ? 00:00:55 /usr/sbin/cupsd
lp   24907 24874  0 11:27 ? 00:00:00 cups-polld 172.xx.xxx.10 631 30 631
lp   24908 24874  0 11:27 ? 00:00:00 cups-polld 172.xx.xxx.11 631 30 631

am if I am not grossly mistaken...
the "30" is the BrowseInterval ... in other words.... my 
specification does not take effect!
and yes! I have restarted cups after changing to value 
"BrowseInterval 0" ..

ideas ??
