Hi Mike, right now the PDF export page size is fixed at 8.5x11" and there isn't any way set up currently to change that. So I guess you would need to open the PDF in Illustrator and change the page size there, before you would be able to print with Acrobat and show the extra area. I don't know myself if there is a way in Acrobat to tell it to print stuff that goes over the current page size or not.
