hi guys, I have my HP photo smart printer plugged into my time capsule. I never had any issues printing with my last laptop (MBA) but i just got a new 13" MBP and can't print. MBP sees the printer on my time capsule via Bonjour, but when I try to add it to my printers i get a dialog box that says: "type the name and password of a user in teh "_Ipadmin" group to allow AddPrinter to make changes." I have no idea what the "_Ipadmin" group is and i've tried all my normal user names & passwords but it tells me they are all wrong. Any ideas would be appreciated. Thanks!
