It is a window (box) which quickly loads and displays a lower quality version of something. This is done so that you can look it over more quickly, before taking the extra time to load the full item or program. For example, if you use a scanner to scan in documents, you hare the option to run a quick preview scan before the full scan. The preview is generated in a fraction of the time the full scan takes, and you can look it over to make sure everything is fine. If you put it in upside-down or the print isn't showing dark enough, you can fix the problem then, and save a little time by not needing to redo the full scan.

Print starts the printing process. Print Preview opens a window showing an example of how the printed pages will look and give you an opportunity to change the page layout if you don't like what you see.
Normally every program (Windows based) has a print preview option. If you look at the top left corner of the window that you are trying to print, there is a File drop-down menu. Click File-Print Preview; it's right above the Print and Exit options.
You can go and click an option called print preview or page preview. It will show your paper exactly how it will look when it prints. It will also let you zoom in and look for mistakes without actually changing something on accident.
