How much margin room does your printer need?
I use PDF-XChange, and there is a setting to allow me to choose the scale. Fit print is usually around 96%, but you might only need 98% if your printer margins are a bit small.
Another option would be to use the "picture" tool to select just what you need to print (ie, not the blank white margins), and then tell it to fit to print.
I downloaded the trial version of PDF-XChange, and that seems to work!
