Just to make sure - is this policy only consulted once on start? IF so than this
is correct. If however the print dialog will change its behavior for consecutive
prints when the policy is flipped than this must be true it doesn't have to flip
the behavior of an already opened print dialog though.

Fixed.

It will change for later prints, as it is consulted each time the
print preview UI is created. However, it is only consulted at dialog
creation, so as you suggested flipping the policy would not affect
a dialog that was already open.
