Can it print yet? I was surprised to discover there was no built in way to print out the text I was editing (on Linux). I do sometimes print out especially gnarly code to think about it on paper.
Since you're just dealing with text files, the easiest solutions would probably be to open the text file on a modern web browser. All modern browsers support printing as far as I'm aware.
If you want syntax highlighting, you can use a tool like highlight [0] or source-highlight [1] to generate an HTML page, which you then open and print with your browser.
