Finding and Fixing Page Numbers that Can’t be Seen and/or Won’t Print
If you have included page numbers at the foot of a page and find that they’re missing from your printouts the problem lies with your page settings. The footer text is being forced to print so far down the paper that your printer is ejecting the paper before this point is reached.
Solve the problem by selecting the Page Layout tab, click the Margins dropdown list, and click Custom Margins. Now, in this dialog select the Layout tab. Finally, increase the From edge: Footer measurement slightly. Experiment to find the smallest increase which will allow your page numbers to print.
