Is there a way to use the includeCssFile tag to include a css file for print media? {% includeCssFile %} can be used to add "regular" css files in the head tag. Is it possible to use this tag for print media?
You can use the {% includeCssFile %}, you just need to make sure and wrap all of the styles in the print stylesheet with @media only print { } or @media print { }

@media only print {
   nav {
       display:none;
   }
   p {
       color:#000000;
   }
   .etc {
   }
}
