I just got an iPod Touch, and have a real strong interest in the iPad. However, the biggest app I need right now is one that will let me scan images from my wifi all-in-one printer/scanner? Preferably one that works with HP, but I'm even willing to try picking up a new device if it works with another brand. I could care less about printing, but I really want to be able to scan images. Anybody have any ideas of what app may do this?
