Print Image Blocked

I am trying to get the button “print coupon” to print an image on another page.

I set the button link to : [print-me target=”#coupon”]

And I added an image below that I would like to be printed.

<!– wp:html –>
<div id=”coupon”>
</div>
<!– /wp:html –>

I also added a 200ms delay on printing.

Nothing seems to work. Please advise

The page I need help with: [log in to see the link]
