This printing situation for businesses is desperate. Has ANYONE out there figured out a way to print on the go? I have a internal customer that works in the field. He wants a way to print to a mobile printer -- literally from his truck or places that don't have PC's or printers readily available. He has an HP 470B, but can't get it to work (or even handshake) with the iPad no matter what printing app he tries. He's open to looking at other mobile printers (or even small non-mobile if he can get it to work on the go) if someone has figured out how to do it or what model to use. Thanks for any help you can provide!
