Answer 1

I tried this way of Chris

@media only print {
.container { display:none !important; }
}

it's work. But when I press F12 to open developer tool, find the line ".container { display:none !important; }" delete it, and then ctrl + p, every thing are show again on print windows. May be have no solution with 100% for prevent print webpage content.
