Print PDF file with highlighted texts using viewer.js

I am using viewer.js and trying to print pdf file with highlighted text in it.

I have tried to print pdf file by selecting background graphic, but it did not work. I have also used
-webkit-print-color-adjust: exact; in @media print but it also did not work.

Print Container

Note: I might be doing in wrong way. Suggesting me to solve in the right directions would be appreciable.
