We just got the ipad 2. Pardon my lack of knowledge if this is a stupid question. I do not have a computer. I have a modem, a router, a Wii, and an android. I want to buy a printer that would work on the ipad 2. Does this exist? And what is the best one? I will be able from time to time take the ipad 2 to a computer to synch. But is the computer necessary to print.
