printing - Word 2010 prints white space (like margins) in document

I have a document that was created in Word 2007. There's no problem when i'm printing it using Word 2007 on other computers.

However, when I print it using Word 2010, it prints white spaces like margins at the top and bottom of the paper.

I checked the page type (Letter, A4) and the margins. How can I fix it without downgrading to 2007?
