Saving contents from inside a div to a PDF file

Question

I implemented jStickyNote to a website here.

If the user tries to close or refresh the page, a warning pops up and takes care of that.

However, I would also like to add functionality to allow a user to save the contents within a div, in this case, the "content" div.

Is it possible to save these sticky notes to a PDF? Or save the content div as an image?

All I can seem to find are solutions for saving to a database, but I don't want that. These need to be able to save to an individual's machine.

<!--Content Start-->
<div id="content" style="width: 1013px; height: 1350px; background: url(images/Whiteboard.png) no-repeat center center;">

        <ul class="stickynote">
            <li id="newsticky"></li>
        </ul>

</div>

Try out it's functionality and you'll see what I'm talking about.
