Your post is a puzzling one. In Preview, I definitely see exactly what actually prints. Where are you getting the "proportion" concept, here? That word appears no where in the print preview or print commands, as far as I can tell.
And, where do you see "'document-build'" mode? At the lower left corner of the Word window, you have small icons representing Normal View, Web Layout View, Print Layout View, Outline View, and Reading Layout, but no "'document-build'" view.
