printing repeating linear gradient from browser

I have a <div>. In it, there is a <p> that on the screen looks like the picture below

enter image description here

I need to have the horizontal rules under each line of the paragraph (horizontal rules marked in red in the picture). The most important thing is that the horizontal rules should take the whole width of the parent <div> so text-decoration: underline won't work here. I drew the lines using repeating linear gradient like this 

p.text--underline {
    line-height: 1.45;
    background: repeating-linear-gradient(
            to bottom,
            transparent calc(1.5em - 1.5px),
            black 1.5em,
            transparent 1.5em,
            transparent calc(3em - 1.5px)
    );
    box-shadow: inset 0 0.5em  white;
}

But the problem is that the horizontal rules are visible in the browsers, but are not visible when printing. I need them to be visible on paper. How to do this?

You can wrap each word with <span> and draw lines with border of each word's :after. You will need to add some JavaScript if the text inside <p> is not fully under your control and you can't wrap words with spans on the server.

var p = document.querySelector('p');
var words = p.textContent.split(/\s+/gm);
p.classList.add('container');
p.innerHTML = words.map(function(w) {
  return '<span class="word">' + w + '</span>';
}).join('\n');
.container {
  position: relative;
}

.word:after {
  content: '';
  display: block;
  position: absolute;
  left: 0;
  width: 100%;
  border-bottom: 1px solid black;
}
<div>

I've tested in Chrome, Firefox and Safari, and it worked fine in all of them.

You can make an HR that's printable without changing browser settings like this:

hr {
    display: block;
    height: 1px;
    background: transparent;
    width: 100%;
    border: none;
    border-top: solid 1px #aaa;
