Welcome to the lousy world of Adobe Acrobat. You can't copy and paste as in normal programs. However
you can print by page. If you look on the bottom of the window, it will tell you what page you're on as you scroll down. Go to FILE, then PRINT, then "Print Range," and you can set up which pages, you want. For example, Page 1-3 or 1-1 or 2-4, or 2-2, etc.
