Wow, thats actually very different from what I expected.
So, now it depends, what is your application right now. If your application is a WEB Based, or textual terminal application it will be very different.
If it is a WEB, so, I think you can try some TWAIN libraries, as this device should support twain.
Or, it looks like it can just export image files somewhere, where you can just catch them.
Can you give some more details about your application and expected workflow?
