I have a Lexmark S305 printer which won't print over wifi however it will happily print a test page.
The printer worked fine before upgrading to Snow Leopard.
I understand the Snow Leopard in built drivers won't allow wifi printing so I have installed the latest Lexmark drivers.
I can access the printer wirelessly by the IP Address.
From the print utility I can cause a test page to be printed.
But if I print anything at all from a regular application it just sits forever in the queue and doesn't even error out.
Does anyone have any clues?
