Again, the theory would be that collapse (including the state of what is on the paper) occurs upon review of the paper.

Consciousness collapse theories are particularly interesting in the context of the quantum eraser variations of the double slit experiment.

Personally my favorite interpretations ever since reading the Asking photons where they've been paper have been ones incorporating forward and backwards wave functions like the two-state vector formalism or the transactional interpretation.

It's thought provoking to look at experimental results under different interpretation contexts, and is one of the things that frustrating in people thinking there's merit to trying to "pick a team."

Not everything needs to be a team sport, and a variety of interpretations tends to be a good thing as each prompts different types of experiments by their various supporters.
