I don't know if native support for printing will ever be added to Sublime Text. Maybe in version 3 ... But for the rare occasions I need it, this plugin works well enough:
SublimePrint. I first created it as a quick hack last april. It was then substantially extended by Kai Ellinger a few months ago, and again cleaned up by me just now. It has been submitted to package control, but you can get it directly from
https://github.com/svenax/SublimePrint until gets is added. Give it a shot.
