Users can also create their own stamps.
What's more, StampIt lets you print multiple copies of the same document, with different stamps on each copy, all in one print session. And you can select the pages that get stamped and those that don't. All stamps can be scaled, rotated and positioned to print anywhere on your page, like in the margins, at the top, bottom, etc. It's completely customizable. You can even leave the stamp in the document - locked in if you want.
