If I want to print a markdown file from GitHub as it appears on screen, for example: https://github.com/RestKit/RestKit/blob/master/Docs/Object%20Mapping.md
Then how can
Here's a super simple solution: Simply select all the text in the readme that you want to print, then print and choose "Only selected text".
This worked perfectly in Chrome (including images) and required no javascript or external sites or downloading or building software.
This is what I tested on: https://github.com/kroitor/gjk.c/blob/master/README.md
