Trick for printing manual for 3 hole punching?

[Rombus]

This sounds stupid, but for the life of me I can't figure out how to print the manual PDFs with different margins to properly clear a 3-hole punch. I'm trying to build a very good copy of all the documentation for my use, but I can't figure or a way to shift it. I know someone has to have a trick out there.

And yes, I could (and probably still will) load all the docs up to a iPad Mini, but after poking at this a few days, it's the principle of the thing!
