Print background image on every page (longread html)

Question

When I print longread html, I can insert background image, but it's work only on the first page. How I can insert bg image on every page?

@media print {
  body {
    background-image: url("something.jpg");
  }
}

Answer 1

You have to write a selector as well to apply the background to:

@media print {
    body {
        background-image: url("something.jpg");
    }
}

Please be aware that you cannot change printer settings - printing background images is usually disabled.
