Trying to print an excel resume without any white spaces in the margins

The goal: to print my Excel resume as a PDF document and submit it for a job.

The problem: despite any adjustments I make to the format of my resume a white margin is always included on my print result. I need the entire page of this resume to be a solid gray color in the background to contrast with the white sections of information.

Attached are two images that will help illustrate the problem. Anyone know how to make this happen?

I was able to solve this problem by expanding the last column (or row) of gray area until the extra white space was nearly gone. Not my ideal solution as it is pretty manual but it got the job done. Resume looked great. Thanks for your response shg.
