I just simply want to know if we can use font awesome icons in printing media query, I mean does they will work like they do on browser or the will just get crashed. Someone please tell me.
If you have the Font Awesome Assets available in your project directory, yes but there were some issues regarding some icons showing as black circles/rectangles, but I don't have any fresh information about that.
As @Mr Lister said, you should try a Print-Preview version of Your website.
There is also a plugin for this under Firefox.
