Have you tried "Center to page" and "Fit to page" in Print Preview? Maybe the content is somewhere off.
In normal drawing view, what happens if you do "Auto Zoom"? Maybe you have accidentally catapulted some elements far away. When you call the view of all elements they then might be very small, even not visible. Check with Select - Select all. They will be highlighted then even if microscopic.
Best to provide the file here for inspection.
