line to indicate outside of page border
I have been struggling to figure out the following: I printed a proof print of a 10×8 inch book page format off of my printer. Originally, the printer printed the image with a thin black line around the edge of the page indicating the outside edge. Now, when I print more proofs this border/page edge is suddenly gone and I need it to be certain of my photo and text placement. How do I get that page-edge line back?
