I have an old Laserwriter 4/600 which uses a LocalTalk - Apple adapter to print out of OSX. Seems that Parallels can't do this for other OSs because there's not AppleTalk support built in - consequently I can't print out of Windows Vista and any version of Linux. I don't think Vista Home has any support for AppleTalk - it would be great to have Parallels provide this layer of support.
