我该如何删除打印机上的打印机图像？

I am printing receipt using following code,but when i click print even printer image is shown in preview and print.My code is

<button onclick="myFunction()">
    <div align="justify">Print</div>
</button>
<script>
    function myFunction() {
        window.print();
    }
</script>
///all code are in html body tag

pls check jsfiddle

Try @media

CSS

@media print {
    .print_img {
        display:none;
    }
}

change you HTML

<div class="print_img">
    <button onclick="myFunction()">
        <div align="justify">Print</div>
    </button>
</div>

fiddle Demo

Use

<button class="printbtn" >Print </button>

  <style>
@media print
  {
  .printbtn {display: none;}
  }
@media screen
  {
  .printbtn {display: block;}
  }
</style>

Well, you could just do it with CSS media queries:

@media print {

   .hide-on-print{
      display:none;
   }

}
