As good as Word is with wysiwyg, the on-screen representation may not exactly reflect what will happen at print time. Try saving the file in PDF format then seeing if it looks OK on the PDF. If not, you may need to scale the image up by the missing couple of points.

In any event, unless your printer does full-width page bleeds, you're going to have a blank border arounf the edges regardless of what you do with the image.
