Don't warn when navigating away from a modified form, if printing has occurred (issue 12262)
Don't warn when navigating away from a modified form, if printing has occurred (issue 12262)

This solution is obviously *not* perfect, since printing being cancelled will thus remove the warning as well. However, a similar problem already exists for saving, since the user may cancel that one as well.

All-in-all, since way cannot really detect with absolute certainty that either saving or printing actually finished, this seems good enough for now.
