I have four networked iMacs. Two are running Panther (10.3.9), one Tiger (10.4.11), and one Leopard (10.5.1). All are wirelessly hooked up to a DSL modem. I can share files between them all great. When I added a USB printer hooked up to one of the Panther computers I was able to add it to the Tiger computer easily. I can't add it to the the computer running Leopard. When I click on the + sign in Print & Fax in System Preferences it is not found. Any suggestions on how I can add this shared networked printer would be appreciated.
