Leopard can’t print to a shared printer
OS X Leopard still seems to have trouble finding printers that are shared on the network from macs running earlier versions of OS X.
Potentially you could waste an enormous amount of time getting this to work. But if you know that the printer should be found by the printer browser, especially if it was working before without Leopard, or other macs simply see the printer, try the following in Terminal:
cupsctl BrowseProtocols=’”cups dnssd”‘
(yes, the various speech marks are intended -use cut and paste to make sure you get them)
Then if you try to add a printer again (remove any previous attempts) the shared printer should appear when you add printer.
