Amy, I did a test print at 82% and it came in at just about the right size. So yes, just change the scale in your print and it'll come out how you want it. You should experiment with different numbers until you find exactly the one that works for you, then print them all out at that scale. A guillotine paper cutter would be a wise investment. I can't live without mine and I use it all the time.
Paul, you can do that in your software that you're using for reading and working with the PDF. In mine, it shows the page numbers in the software but it doesn't print the numbers to the paper. I think they intentionally left off numbers because everybody will use the printed pages in completely different order.
