I saw that when i opened my printer it had a slip that said if i have lion, not to use the install disk that comes with it, but to use the one online, so i did. I have a macbook pro that's updated to 10.7.2 (i think i'm at 2, or maybe 1). I just got a new Photosmart 6510 e-all in one printer that works wirelessly.
