HTML元素不打印

我正在使用 this library生成条形码,我需要打印包含条形码的页面.

当我启动打印对话框时,虽然占用空间,但我找不到条形码.

$(document).ready(function() {
  window.print();
});

@media print {
  .barcode-container {
    display: block !important;
  }
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="subpage">
  <div class="barcode-container">

我试着做一个显示：阻止！重要;到条形码容器但它仍然没有打印它.有任何想法吗？

解决方法

默认情况下不打印背景颜色.它们被设置为透明的.

尝试：

Box-shadow: inset 0 0 0 10000px #000; /*Fake Bg*/

或者,用户可以设置：

从浏览器的“页面设置”中选中“打印背景颜色和图像”

您也可以使用：

-webkit-print-color-adjust: exact;

但这仅在Chrome(和其他Webkit浏览器)中受支持.
