How to print a booklet at 100%

[Document Geek]

How can I print a booklet at 100%? When I print a booklet from Acrobat, it shrinks it slightly, about 5% or so (which I guessing is scale to fit). But I need the booklet printed at exactly 100%. Is this possible?

I have every version of Acrobat from version 9 all the way up to DC, so I can use whichever one that will get the job done. I am on a mac.

Thanks for all the suggestions here, but my problem appeared to be that I had used Word "print to PDF" instead of "save to PDF" to save the original document. With the "print to PDF" version, I was running into the 1" margins that couldn't be changed so the booklet pages were much smaller than intended. After opening the "Save to PDF" version, Acrobat printed the booklet just fine. Why did I use "print to PDF"? Well, I'm old and habits learned years ago still persist.

Interesting.  I have used "print" or "save" interchangeably and never knew they were functionally different.  Unfortunately the one I was having a problem with was prepared by someone else and I can't ask them to redo it.
