I was thinking backwards : trying to do it from inside Acrobat instead of from the printer properties. Thanks, I'll try it. Last resort, read the manual!!
I've done that already (run it through twice) on a black and white laser printer, and it worked fine, but I'm afraid of what would happen to the ink on the previous copies with my color inkjet. I think I can get ~9 N scale planes on 1 sheet of paper. I'm not that cheap, well ok, maybe I am.
A "Custom" page size is how I made the b&w copies. Worked fine.
How far from the line are you? I work in New Castle. Lived in Harrisburg for 6 years, which is why I live in OH and work in PA now.
