So when you have the printed copy, why not just hand it over together with the passport as it is meant. That is more efficiënt for you and for the IO. The fact that it also might work when yo do not hand over the printed copy is not relevant, because you cannot trust it might work this way, and as such it is not a good answer. The only correct answer to the OP's question is that he should hand over the printed copy together with the passport and that not doing so, sometimes might work and sometimes might not work. And presenting a printed copy is not difficult, so I don't understand why some people try to prevent showing it. Why don't you try to do the same with your passport? Only tell IO you have a passport? I really don't understand the fun of this game with IO.
