Background color not showing in print preview

Question

I am trying to print a page. In that page I have given a table a background color. When I view the print preview in chrome its not taking on the background color property...

So I tried this property:

-webkit-print-color-adjust: exact; 

but still its not showing the color.

http://jsfiddle.net/TbrtD/

.vendorListHeading {
  background-color: #1a4567;
  color: white;
  -webkit-print-color-adjust: exact; 
}


<div class="bs-docs-example" id="soTable" style="padding-top: 10px;">
  <table class="table" style="margin-bottom: 0px;">
    <thead>
      <tr class="vendorListHeading" style="">
        <th>Date</th>
        <th>PO Number</th>
        <th>Term</th>
        <th>Tax</th>
        <th>Quote Number</th>
        <th>Status</th>
        <th>Account Mgr</th>
        <th>Shipping Method</th>
        <th>Shipping Account</th>
        <th style="width: 184px;">QA</th>
        <th id="referenceSO">Reference</th>
        <th id="referenceSO" style="width: 146px;">End-User Name</th>
        <th id="referenceSO" style="width: 118px;">End-User's PO</th>
        <th id="referenceSO" style="width: 148px;">Tracking Number</th>
      </tr>
    </thead>
    <tbody>
      <tr class="">
        <td>22</td>
        <td>20130000</td>
        <td>Jim B.</td>
        <td>22</td>
        <td>510 xxx yyyy</td>
        <td>[e-mail]</td>
        <td>PDF</td>
        <td>12/23/2012</td>
        <td>Approved</td>
        <td>PDF</td>
        <td id="referenceSO">12/23/2012</td>
        <td id="referenceSO">Approved</td>
      </tr>
    </tbody>
  </table>
</div>

Answer 1

That CSS property is all you need it works for me...When previewing in Chrome you have the option to see it BW and Color(Color: Options- Color or Black and white) so if you don't have that option, then I suggest to grab this Chrome extension and make your life easier:

https://chrome.google.com/webstore/detail/print-background-colors/gjecpgdgnlanljjdacjdeadjkocnnamk?hl=en

The site you added on fiddle needs this in your media print css (you have it just need to add it...

media print CSS in the body:

@media print {
body {-webkit-print-color-adjust: exact;}
}

UPDATE OK so your issue is bootstrap.css...it has a media print css as well as you do....you remove that and that should give you color....you need to either do your own or stick with bootstraps print css.

When I click print on this I see color.... http://jsfiddle.net/rajkumart08/TbrtD/1/embedded/result/

I used purgatory101's answer but had trouble keeping all colours (icons, backgrounds, text colours etc...), especially that CSS stylesheets cannot be used with libraries which dynamically change DOM element's colours. Therefore here is a script that changes element's styles (background-colour and colour) before printing and clears styles once printing is done. It is useful to avoid writing a lot of CSS in a @media print stylesheet as it works whatever the page structure.

There is a part of the script that is specially made to keep FontAwesome icons color (or any element that uses a :before selector to insert coloured content).

JSFiddle showing the script in action

Compatibility: works in Chrome, I did not test other browsers.

function setColors(selector) {
  var elements = $(selector);
  for (var i = 0; i < elements.length; i++) {
    var eltBackground = $(elements[i]).css('background-color');
    var eltColor = $(elements[i]).css('color');

    var elementStyle = elements[i].style;
    if (eltBackground) {
      elementStyle.oldBackgroundColor = {
        value: elementStyle.backgroundColor,
        importance: elementStyle.getPropertyPriority('background-color'),
      };
      elementStyle.setProperty('background-color', eltBackground, 'important');
    }
    if (eltColor) {
      elementStyle.oldColor = {
        value: elementStyle.color,
        importance: elementStyle.getPropertyPriority('color'),
      };
      elementStyle.setProperty('color', eltColor, 'important');
    }
  }
}

function resetColors(selector) {
  var elements = $(selector);
  for (var i = 0; i < elements.length; i++) {
    var elementStyle = elements[i].style;

    if (elementStyle.oldBackgroundColor) {
      elementStyle.setProperty('background-color', elementStyle.oldBackgroundColor.value, elementStyle.oldBackgroundColor.importance);
      delete elementStyle.oldBackgroundColor;
    } else {
      elementStyle.setProperty('background-color', '', '');
    }
    if (elementStyle.oldColor) {
      elementStyle.setProperty('color', elementStyle.oldColor.value, elementStyle.oldColor.importance);
      delete elementStyle.oldColor;
    } else {
      elementStyle.setProperty('color', '', '');
    }
  }
}

function setIconColors(icons) {
  var css = '';
  $(icons).each(function (k, elt) {
    var selector = $(elt)
      .parents()
      .map(function () { return this.tagName; })
      .get()
      .reverse()
      .concat([this.nodeName])
      .join('>');

    var id = $(elt).attr('id');
    if (id) {
      selector += '#' + id;
    }

    var classNames = $(elt).attr('class');
    if (classNames) {
      selector += '.' + $.trim(classNames).replace(/\s/gi, '.');
    }

    css += selector + ':before { color: ' + $(elt).css('color') + ' !important; }';
  });
  $('head').append('<style id="print-icons-style">' + css + '</style>');
}

function resetIconColors() {
  $('#print-icons-style').remove();
}

And then modify the window.print function to make it set the styles before printing and resetting them after.

window._originalPrint = window.print;
window.print = function() {
  setColors('body *');
  setIconColors('body .fa');
  window._originalPrint();
  setTimeout(function () {
    resetColors('body *');
    resetIconColors();
  }, 100);
}

Answer 3

Chrome will not render background-color, or several other styles, when printing if the background graphics setting is turned off.

This has nothing to do with css, @media, or specificity. You can probably hack your way around it, but the easiest way to get chrome to show the background-color and other graphics is to properly check this checkbox under More Settings.

Answer 4

You can also use the box-shadow property.

Answer 5

I just needed to add the !important attribute onto the the background-color tag in order for it to show up, did not need the webkit part:

background-color: #f5f5f5 !important;

Answer 6

Your CSS must be like this:

@media print {
   body {
      -webkit-print-color-adjust: exact;
   }
}

.vendorListHeading th {
   background-color: #1a4567 !important;
   color: white !important;   
}
