Help with Twenty Eleven Child Theme Print styles

I have set up a child theme based on Twenty Eleven. I would like to have it print on paper just like it looks on screen.

So I would like the top navbar to print, I want the header and site title to look the same on the page as on the screen, and I want the sidebars to print on pages that have them.

For some reason my print styles in my style sheet are being ignored: is this a syntax error?

Isn’t there an easy way to do this?
