On Android devices (I have tested Nexus 5, Nexus 10, Galaxy S4 and Galaxy Tab 3), the window.print() command in JavaScript doesn\'t do anything. As far as I can
I think, direct print() method is disabled on devices by default. I not saw so many phones or other Android devices with printer, however by USB it should be possible of course.
Instead, recommended is saving content/page as pdf and print it via some cloud print service.
