How to print HTML content on click of a button, but not the page? [duplicate]

@media print {
  .noPrint{
    display:none;
  }
}
h1{
  color:#f6f6;
}

<h1>
print me
</h1>
<h1 class="noPrint">
no print
</h1>
<button onclick="window.print();" class="noPrint">
Print Me
</button>

I came across another elegant solution for this:

Place your printable part inside a div with an id like this:

<div id="printableArea">
      <h1>Print me</h1>
</div>

<input type="button" onclick="printDiv('printableArea')" value="print a div!" />

Now let’s create a really simple javascript:

function printDiv(divName) {
     var printContents = document.getElementById(divName).innerHTML;
     var originalContents = document.body.innerHTML;

     document.body.innerHTML = printContents;

     window.print();

     document.body.innerHTML = originalContents;
}
