I'm trying to print a bill that is legal size, but I would like to just print the bottom portion onto letter size paper. When I ask it to print on letter size paper, it defaults to printing the middle of the document. Is there any way to control that?
You can't print part of a page. However, you should be able to print with shrink to fit. Another option would be to capture the part you want and copy that to a graphic package and print the image you obtained.
You can print a region of the page by using the Snapshot tool, but it prints as a graphic object.
Note that this method cannot currently be used to print back to PDF.
