So - if the app isn't responding in time, you have two options

a. slow down the human
b. speed up the app

Sorry, there's some confusion i think. The situation so far is that the application (of which jpos is part) cannot keep up with the scanning. Is that correct?

Application is fine, that suppose to take that much time, as i mentioned in my question, we need to slow down scanner. jpos control is where we need to make change.

Tell the human to wait longer, and to move the scanner more slowly.

Well of course the user might still consider it broken as the scanner won't respond at the speed they want ;) IOW, that's the next best thing to my choice a. remedy
