[after Fred's post]
ok, I see the change. The dimensions of the printed page is 4 times larger than before pb4.7. So now my page is 2448 x 3168 pixels. That would calculate out to a 12 pt text size needing to be printed out at (12x4) 48 pt and all the images will also have to be 4 times larger (resized). I would guess that the new size is used to sharpen up the drawing to the printer.
