Printer does not print full page, AND what's the squeaking I hear??

I am really new to all this, hope someone can help me. When trying to print out an article someone has sent, several words on the right hand side of the entire article do NOT get printed, I guess the page is too wide so I end up with incomplete sentences. How can I fix this?. Also, does anyone know WHAT that squeaking sound could be? Sounds like an old creaky door opening and shutting! I only hear it once in a while. I have asked several people and no one knows! Thanks for the help, there is a lot to learn!
