'Bootstrap grid for printing
I would like to design a report page with a different layout for printing to mobile. I am using bootstrap v3. It seems the grid can't differentiate between the two as the breakpoint for printing is the same as the breakpoint for mobile (xs)
For example: In the below test html my printed page (or print preview) shows the xs6 columns side by side but the sm6 columns stacked. There isn't a breakpoint between xs and sm.
Surely my printed page is wider than my mobile viewport so shouldn't it use the sm layout?
Am I doing something wrong or is this the way it is? Is there a defined viewport width for printing?
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Test</title>
<link rel="stylesheet" href="http://netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css">
</head>
<body>
<div class="container">
<div class="row">
<div class="col-xs-6">
xs6
</div>
<div class="col-xs-6">
xs6
</div>
</div>
<div class="row">
<div class="col-sm-6">
sm6
</div>
<div class="col-sm-6">
sm6
</div>
</div>
</div>
</body>
</html>

What I did was to manually recreate those columns classes in my print css.
.col-print-1 {width:8%; float:left;}
.col-print-2 {width:16%; float:left;}
.col-print-3 {width:25%; float:left;}
.col-print-4 {width:33%; float:left;}
.col-print-5 {width:42%; float:left;}
.col-print-6 {width:50%; float:left;}
.col-print-7 {width:58%; float:left;}
.col-print-8 {width:66%; float:left;}
.col-print-9 {width:75%; float:left;}
.col-print-10{width:83%; float:left;}
.col-print-11{width:92%; float:left;}
.col-print-12{width:100%; float:left;}
Then I just use those classes like I use bootstrap classes to make my columns for print only. I also created .visible-print and .hidden-print to hide/show elements only in the print version.
It still needs some work, but that quick patch helped me a lot.

If you want the Bootstrap's grid do not print with col-xs (mobile settings) , and want to use col-sm-?? instead , Based on Fredy31 answer and you don't even need to define col-print-??. simply rewrite all col-md-?? css class definitions inside a: @media print { /* copy and paste from bootstrap.css*/ } like this:
@media print {
.col-sm-1, .col-sm-2, .col-sm-3, .col-sm-4, .col-sm-5, .col-sm-6, .col-sm-7, .col-sm-8, .col-sm-9, .col-sm-10, .col-sm-11, .col-sm-12 {
float: left;
}
.col-sm-12 {
width: 100%;
}
.col-sm-11 {
width: 91.66666667%;
}
.col-sm-10 {
width: 83.33333333%;
}
.col-sm-9 {
width: 75%;
}
.col-sm-8 {
width: 66.66666667%;
}
.col-sm-7 {
width: 58.33333333%;
}
.col-sm-6 {
width: 50%;
}
.col-sm-5 {
width: 41.66666667%;
}
.col-sm-4 {
width: 33.33333333%;
}
.col-sm-3 {
width: 25%;
}
.col-sm-2 {
width: 16.66666667%;
}
.col-sm-1 {
width: 8.33333333%;
}
}

The Sass version of Fredy31 solution:
@for $i from 1 through 12 {
.col-print-#{$i} {
width: #{percentage(round($i*8.33)/100)};
float: left;
}
}
Solution 4:[4]
For Bootstrap 4 (using SASS)
@each $breakpoint in map-keys($grid-breakpoints) {
@include media-breakpoint-up($breakpoint) {
$infix: breakpoint-infix($breakpoint, $grid-breakpoints);
@for $i from 1 through $grid-columns {
@media print {
.col-print#{$infix}-#{$i} {
@include make-col($i, $grid-columns);
}
}
}
}
}
will create
@media print {
.col-print-1 {
flex: 0 0 8.33333%;
max-width: 8.33333%; } }
@media print {
.col-print-2 {
flex: 0 0 16.66667%;
max-width: 16.66667%; } }
@media print {
.col-print-3 {
flex: 0 0 25%;
max-width: 25%; } }
@media print {
.col-print-4 {
flex: 0 0 33.33333%;
max-width: 33.33333%; } }
@media print {
.col-print-5 {
flex: 0 0 41.66667%;
max-width: 41.66667%; } }
@media print {
.col-print-6 {
flex: 0 0 50%;
max-width: 50%; } }
@media print {
.col-print-7 {
flex: 0 0 58.33333%;
max-width: 58.33333%; } }
@media print {
.col-print-8 {
flex: 0 0 66.66667%;
max-width: 66.66667%; } }
@media print {
.col-print-9 {
flex: 0 0 75%;
max-width: 75%; } }
@media print {
.col-print-10 {
flex: 0 0 83.33333%;
max-width: 83.33333%; } }
@media print {
.col-print-11 {
flex: 0 0 91.66667%;
max-width: 91.66667%; } }
@media print {
.col-print-12 {
flex: 0 0 100%;
max-width: 100%; } }

Your switch styles like this
<div class="row">
<div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
<div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
<div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
</div>
See
#grid-example-mixed or #grid-example-mixed-complete
and may you need to clearfix
<!-- Add the extra clearfix for only the required viewport -->
<div class="clearfix visible-xs"></div>
Edit: 04/2019
Since Bootstrap 4.x there are new classes that can be used to set the display behavior when printing. SEE 4.3 Docs

I had a similar problem, for me the easiest solution was to manually modify the width for elements I wanted to appear differently when printed (and I added a specific class -in my case: title-container, details-container for those, along the col-xs-6 etc.).
For example:
<div class="jumbotron">
<div class="container">
<div class="row">
<div class="col-xs-12 col-ms-3 col-sm-6 col-md-6 title-container">
Some stuff
</div>
<div class="col-xs-12 col-ms-9 col-sm-6 col-md-6 details-container">
Some more stuff
</div>
</div>
</div>
</div>
@media print {
.title-container {
width: 360px;
float: left;
}
.details-container {
width: 300px;
float: right;
}
}
In my case I needed a column to be floated on the right, one to the left, thus the floats... You could set in your custom css the width also for .col-xs-6 etc. just a quick and dirty solution, but did the job for a page where I needed this...

Instead of recreating with new column names like .col-print-1 , .col-print-2 , write a media query which will be enable while printing the document.
@media print {
.col-md-1,.col-md-2,.col-md-3,.col-md-4,
.col-md-5,.col-md-6,.col-md-7,.col-md-8,
.col-md-9,.col-md-10,.col-md-11,.col-md-12 {
float: left;
}
.col-md-1 {
width: 8%;
}
.col-md-2 {
width: 16%;
}
.col-md-3 {
width: 25%;
}
.col-md-4 {
width: 33%;
}
.col-md-5 {
width: 42%;
}
.col-md-6 {
width: 50%;
}
.col-md-7 {
width: 58%;
}
.col-md-8 {
width: 66%;
}
.col-md-9 {
width: 75%;
}
.col-md-10 {
width: 83%;
}
.col-md-11 {
width: 92%;
}
.col-md-12 {
width: 100%;
}
}
So by this way we can be able to apply print css styles directly without changing the column names.

The following works great to create grid elements specific for print media. Using Bootstrap 3.
@media print {
.make-grid(print);
}
Then you can use all the grid col elements with the print keyword. Ex: col-print-6 col-print-offset-2, etc.
Solution 9:[9]
Maybe you could use Bootstrap 2. If you are familiar with Bootstrap 2, then you can use it as an alternative, as this offers non responsive CSS. Bootstrap 2 was not mobile first, you had to add an extra style sheet to make your web pages responsive.
Or you can add clearfixes for the mobile part. See http://getbootstrap.com/css/#grid-responsive-resets

And the SASS version of Ehsan Abidi's answer using MiCc83's answer:
@for $i from 1 through 12 {
.col-sm-#{$i} {
width: #{percentage(round($i*8.33)/100)};
float: left;
}
}
I prefer this because I always spec the "sm" size and that most closely approximates a print page in my applications. Then I only need to add something specifically for print when I've got an outlier condition.

If you only have 2 columns, you can try it. I fixed it with the code below.
<div class="row">
<div class="w-50 p-3 float-left">
</div>
<div class="w-50 p-3 float-right">
</div>
</div>

If it's just one line of text in two columns you can use the accepted answer here.

For Bootstrap 4 sass here are some snippets that I applied across several projects. These are making adjustments on:
- Grid (follows the LG breakpoint)
- Spacers (rewrite all below LG margins/paddings)
- Buttons (since background-colors does not work in print preview, switch filled buttons to outline)
- Display (rewrite all below LG displays)
- Text alignments (rewrite all below LG breakpoint)
@media print {
$grid-breakpoints-print: (lg: 992px); // keep breakpoint that you would like to apply for print
/* Rewrite margins, padding, display & alignment to keep the LG and not the mobile ones */
@each $breakpoint in map-keys($grid-breakpoints-print) {
$infix: breakpoint-infix($breakpoint, $grid-breakpoints-print);
// rewrite all displays for your print breakpoint
@each $value in $displays {
.d#{$infix}-#{$value} {
display: $value !important;
@each $v in $displays {
&.d-#{$v} {
display: $value !important;
&.d-print-none,
&.table__sort {
display: none !important;
}
}
}
&.d-print-none {
display: none !important;
}
}
}
// rewrite all spacings for your print breakpoint
@each $prop, $abbrev in (margin: m, padding: p) {
@each $size, $length in $spacers {
.#{$abbrev}#{$infix}-#{$size} {
#{$prop}: $length !important;
@each $s, $l in $spacers {

Based on Fredy31's answer using Bootstrap's exact widths and removing repetition of float left.
[class^="col-print"] {float:left;}
.col-print-1 {width:8.33333333%;}
.col-print-2 {width:16.66666667%;}
.col-print-3 {width:25%;}
.col-print-4 {width:33.33333333%;}

.col-print-7 {width:58.33333333%;}
.col-print-8 {width:66.66666667%;}
