Trying to print a doc created in Word, two-sided, bookfold. When I save as PDF and print, the text is too small and doesn't fit the page. Please help!

I have created a Word document for a directory for a small church.  It is two columns (Table) per page with a book fold, left, printed on both sides, Landscape.  It looks great on the screen. The font is 11.  I save it as a PDF and it works perfectly EXCEPT it changes the font and doesn't "fit the screen" properly.  Any suggestions?

I just purchased Acrobate Pro DC hoping that it would allow me increase the font.  I probably just don't know how to do that in Acrobat.  My printer is an Epson 3540 and is working perfecting for all other formats.
