Ha! Good luck :)

It took me an enormous amount of time to get this feature to work.
Acutally it was a 2-man job ... each of us taking it in turns while the 
other one went out for a cigarette break and a vodka :)

You need the following options:

---

Browsing On
BrowseProtocols cups
BrowseAddress 10.146.255.255
BrowseAllow 10.146.0.0/10.146.255.255
BrowseInterval 30
BrowseOrder allow,deny
BrowsePort 631

Right, now firstly, you need to modify the ip addresses to fit your 
network. The BrowseAddress should be at the end of your network range ( 
ending in 255.255 ). I'm not networking expert, so forgive me if the 
above description isn't particularly accurate. The BrowseAllow is the 
range of addresses that are allowed to browse.

Next, you may or may not need the following options set. Like I said, it 
took us a *lot* of mucking around to get it to work, and by the end we 
were so confused / frustrated that we really have no idea how we finally 
got it working.

You need to define each of your printers in the cupsd.conf file as above 
for browsing to work. The 'Allow From @LOCAL' option by itself doesn't 
work for us, but I *think* adding the 'Allow From 
10.146.0.0/10.146.255.255' line may have helped us getting browsing working.

Give the above a go. If you still can't get it working, try waving a 
dead chicken in the air and reciting from the bible backwards :) If this 
still doesn't work, post back and I'll give you my whole damned 
/etc/cups directory and you can copy and paste to your heart's content.
