I agree with arkturez. In inventory management, you need certainty. AI photo-recognition will be tricky, unless you make some sort of new-fangled pseudo-barcode, like a series of color dots in the upper right corner. So you are still printing.

I can just see the hours it took to trace down the bug, "why you bought 500 bikini bottoms instead of jogging shorts" , due to the sunlight angle at 3PM on cash register #3.
