When a small worksheet is printed for sharing by PDF or printing on paper, it will appear in the upper left corner of the page like this:
A more professional presentation would center the information on the page. In Page Layout, there are options to center horizontally, vertically or both:

2. Click on the Margins tab and then check Horizontally, Vertically, or both. Then click OK.
In this example, centering horizontally looked best.
