When in the process of creating a document, one occasionally uses two or
three pages. But when the finished document only applies to one or two pages,
the blank extra pages remain in the file. This creates a problem for
printing, when the extra blank pages are printed if one forgets to specify
which pages to print.

How do I permanently remove extra blank document pages?
