I have a new Imac 20" and have just purchased a Lexmark X3480 printer. Unfortunately all of the drivers etc on the supplied disc are in PC format so I cant load them. I have connected the printer via a USB cable but the Imac does not print anything. I cant see the driver on the imacs list. Can anyone help. Ive been to Lexmarks web site to try to download a driver but it's not on there.
