Scott,
you could try to open the PDF file with Adobe Acrobat Reader and then adjust the zooming (enlargement) level in the Print propierties page (just click on "Print" in the File menu on the left and when the page appears there should be a pop down menu to the effect of resizing the page: choose "Adapt to the printing area" (or something like that: my program is in written italian) and you should be done
