Don't show a progress bar when previewing for the Qt print dialog.

We don't do much work to do that - we don't print anything before the
first selected page, and once we're finished generating that page, we
terminate the printing process - so it shouldn't need a progress bar.
(If it needs a progress bar, We Have A Problem, as that slows down the
drawing of the dialog box.)

This should prevent the problem seen in bug 12040.
