An 11 x 17 PDF whos orientation is landscape does not import correctly as an image resource. It imports with a portrait orientation; however, it prints landscape, but cuts off the 17 inches at 11 inches because it's oriented portrait. If you rotate it to landscape using the 'Angle' property it prints portrait, off the page. When you open the PDF for editing in Acrobat, it is landscape. The work-around is to make all of your PDFs portrait.
