Changed in Chrome 32 35+
(In Chrome 35+ the "Emulation" tab is present by default. Also, the console is available from any primary tab.)
In DevTools, go to settings-> Overrides
enable "Show Emulation view in console drawer"
Close settings, go to 'Elements' tab
- Hit Esc to bring up console
- Choose tab "Emulation", click "Screen"
- Scroll down to "CSS Media", select "print"
This option is not (yet?) available in the console tab.
