I have done, for code that fits on 2-8 pages (basically a demonstration program). I used vim's ":hardcopy", so the printed code was already syntax-highlighted in the way I was used to. This did let me work on the code when away from my workstation, but I didn't otherwise find it very helpful. If you have lots of code, some form of code navigation is very helpful.
