Trouble exporting?

My school is 95% Pc and the Macs don’t even have iWork installed. Whenever I write a paper I always like to play around with the design and layout with the ease that Pages gives me. Now my question is, is there a way I can export a paper (or Pages file) as a .jpg or .png so I don’t always have to take screen shots of the page and stitch them together so I will be able to print them on a Pc? I don’t have a printer at home (not yet) so I always have to print them at school or public computers using Windows.
