Export dimensions are inferred from the configured [presentation size](#presentation-size). Slides that are too tall to fit within a single page will expand onto multiple pages. You can limit how many pages a slide may expand onto using the `pdfMaxPagesPerSlide` config option, for example `Reveal.configure({ pdfMaxPagesPerSlide: 1 })` ensures that no slide ever grows to more than one printed page.
### Print stylesheet
To enable the PDF print capability in your presentation, the special print stylesheet at [/css/print/pdf.css](https://github.com/hakimel/reveal.js/blob/master/css/print/pdf.css) must be loaded. The default index.html file handles this for you when `print-pdf` is included in the query string. If you're using a different HTML template, you can add this to your HEAD:
```html
<script>
var link = document.createElement( 'link' );
link.rel = 'stylesheet';
link.type = 'text/css';
link.href = window.location.search.match( /print-pdf/gi ) ? 'css/print/pdf.css' : 'css/print/paper.css';
document.getElementsByTagName( 'head' )[0].appendChild( link );
</script>
```
### Instructions
1. Open your presentation with `print-pdf` included in the query string i.e. http://localhost:8000/?print-pdf. You can test this with [revealjs.com?print-pdf](http://revealjs.com?print-pdf).
