Got an iPad for Christmas. I am going to be taking Family Medical Leave to care for my elderly Mother for a couple of months and want to buy a printer to take with me for my iPad. She doesn't have a computer, wireless service, nothing. I have subscribed to the 3G whatever it's called so I can use my iPad at her house. What should I get for a printer? Can the iPad even use a regular old plug in the wall printer? I am not smart about computers and don't know all the lingo so try to use simple terms if possible. Thanks!
