On print button i am using something like this:
onclick="window.print();"
And i have found below pieced of code to make checkbox checked by default:
<style type="text/css" media="print">
* {
-webkit-print-color-adjust: exact !important; /*Chrome, Safari */
color-adjust: exact !important; /*Firefox*/
}
</style>
It works if the Print options appear without more settings as below:
However it is not working if the Print has more setting and we need to click down arrow button to look Background graphics checkbox inside Options:
Any idea how it can be checked by default for all browsers type ?
