In that case, you probably do not want to share the printer over the network. The text of the checkbox could be a bit clearer - something like over the network instead of over the Internet. >> On every machine that you want to administer from another machine, make >> sure the "Allow remote administration" box is checked.

I tend to be paranoid, and there may be a way to get CUPS into an add printer loop. (Machine 1 shares the printer, machine 2 shares machine 1's printer, and advertises it as a printer available for use on machine 2. machine shares both machine 1's and machines 2's advertised printers, and also advertises them as its available printers, etc...) You should not be able to do it, but someone may manage to do it anyway. Mikkel -- Do not meddle in the affairs of dragons, for thou art crunchy and taste good with Ketchup!
