All PDFs created by ISN use the same settings for "zooming" and "margins."
Go to Settings -- Office Settings -- My Office Settings - PDF Options
Next, you can adjust the Margins and the Zoom
The Zoom is typically the most adjusted setting. You can have a zoom between zero and one (0 - 1).
e.g. A zoom of 1 will be 100% and a zoom of 0.50 will be a zoom of 50%.
