Answer : I'm most case i will expect the print in the non horizontal version maybe? In your case you could try to apply the grid rules on the print media query. In the case you use the small grid (col-sm-*) default, b.e. <div class="container"> <div class="row"> <div class="col-sm-6">Left</div> <div class="col-sm-6">Right</div> </div> </div> <!-- /container --> In your grid.less replace @media (min-width: @screen-tablet) { with @media (min-width: @screen-tablet), print { (add print, see: CSS media queries: max-width OR max-height) Recompile bootstrap and your pdf will have left / right just like screen now.

This works great when you have white media, as "printing no ink" simply leaves the white exposed, but as you can imagine, this doesn't work for non-white media. If you don't have a base color to subtract from (i.e., Black ), then it doesn't matter what you subtract from it, you still have the color Black. As others are pointing out, there are special printers which can operate in the CMYW color space, or otherwise have a white ink or toner. These can ...
