In case someone is looking for a solution for Bootstrap v2.X.X here. I am leaving the solution I was using. This is not fully tested on all browsers however it could be a good start.
1) make sure the media attribute of bootstrap-responsive.css is screen.
<link href="/css/bootstrap-responsive.min.css" rel="stylesheet" media="screen" />
2) create a print.css and make sure its media attribute print
<link href="/css/print.css" rel="stylesheet" media="print" />
3) inside print.css, add the "width" of your website in html & body
html,
body {
width: 1200px !important;
}
4.) reproduce the necessary media query classes in print.css because they were inside bootstrap-responsive.css and we have disabled it when printing.
.hidden{display:none;visibility:hidden}
.visible-phone{display:none!important}
.visible-tablet{display:none!important}
.hidden-desktop{display:none!important}
.visible-desktop{display:inherit!important}
Here is full version of print.css:
html,
body {
width: 1200px !important;
}
.hidden{display:none;visibility:hidden}
.visible-phone{display:none!important}
.visible-tablet{display:none!important}
.hidden-desktop{display:none!important}
.visible-desktop{display:inherit!important}
