FR: Dynamic highlights when printing to PDF

[universemaster]

I'd like (an option) so that when I print to PDF, the dynamic highlights that I see in live preview mode are present on the exported PDF.

The way I see it, there are two reasons to use dynamic highlights:

1. As helpers when editing
2. To keep the markdown source clean, and not have to wrap things in spans with classes.

I am most interested in the second type, which means I need it to persist when printing the PDF.
