Back in the Visual Studio 2010 days there was a request for Printing source code with syntax coloring.
Then, the Visual Studio team released an extension that did just that: Color Printing Extension Now Available! – The Visual Studio Blog – Site Home – MSDN Blogs.
It got updated for Visual Studio 2012 in the gallery Color Printing extension, but that does not mention it has moved to the Productivity Power Tools 2013 extension.
Both tools are from the Visual Studio IDE team, and mentioned on their blog.
