You can't do that without changing the page size and, even if you do that, it won't reduce the amount of paper used when you print unless you change the paper size too.

For a PDF, this is all pretty pointless. If you want to fill the page, use a larger font as Charles suggested. Do be aware that those who have to evaluate such a CV are likely to be less than impressed.
