R Markdown HTML Output in Chrome loses coloring when print to PDF from Chrome

Question

For Example:

Series/Episode: r paste0(stats['this_week_episode']) -r paste0(stats['this_week_debut_date'])

---

Within the HTML view in Chrome the coloring is blue. However, when I print to PDF from Chrome I lose all formatting. This doesn't happen with other web pages (google, indeed etc.) which leads me to believe it's an R Markdown setting or formatting function.

Thanks for any advice!
