Integrate print styles in Omega 4 What is the right or omega way of integrating print styles in omega 4?

I've found no references in the docs.
Like for any css file, add it into the theme's info file, but rather than 'all', just specify it to be only for print.

stylesheets[all][] = css/everytime.css
stylesheets[screen][] = css/screen-only.css
stylesheets[print][] = css/print-only.css
