This plugin has been substantially updated and can now print the entire file, the selected text (multiple selections too), or the current clipboard. It has been submitted to package control, but you can get it directly from Github until it gets added.
The plugin uses an external command line program to print. As of now, it uses GNU enscript, which is easily available for Linux and Mac. The program is also available for Windows, but may be somewhat harder to install. I haven't tried that myself, but if someone wants to give it a shot, please let me know if it works.
