Ignorant question, if privacy didn’t matter and they had an atomically identical machine, would there still be plenty of edge cases where it was the printer or the Wi-Fi causing the issue?

In any case I would have said it sounds difficult on every front

I should be more precise. Capturing the system state isn’t too hard. Turning that into a reproducer may be quite hard, because of things like you say. There are certainly a lot of bugs that such a capture would make easier to figure out, but it wouldn’t be a panacea.
