If you want to share your printers without hair loss and raised blood pressure, do it my way. Edit /etc/cups/cupsd.conf and forget all the GUI junk. This article tells how to share printers the right way in Linux. (This page lists more good Linux tutorials.)

The printer article has one error that I recently discovered the hard way, though I suspect that something changed during a routine update, because it worked fine before--get rid of all the policy junk in cupsd.conf. I had network printing working fine, then suddenly it stopped working. Deleting all the policy crud cured it. That's the directives between the <Policy> </Policy tags >. Blow it all away--it won't hurt a thing, and you'll be instantly happier. Moral: don't lard up configuration files with useless stuff, especially when it doesn't work.
