Hello, I'm having problems printing page numbers on my documents no matter if I put the page number in the header or footer area. They show up on my computer screen but do not show up in the print preview or when I actually print the page out. Why is that?

Sounds like you are placing the page number outside the printable area. If you are using Office, this will be a better place to pose your question http://answers.microsoft.com/en-gb/office/default.aspx#tab=1
