I am using the background-color property in CSS media type print.
The problem is that Google Chrome does not show background-colo         
        
Chrome supports control of background colour / image printing via CSS. You can set the following CSS property on elements whose background should be printed:
-webkit-print-color-adjust: exact;
Normally of course, this is determined by browser settings - but Chrome allows web designers to determine how backgrounds are printed on a per-element basis...
Notes:
Thanks to Cron’s Web Tech Blog, where I first spotted it:-

Also, this leads to some background (no pun intended!) info regarding the feature:-

Hope this helps...
