参考vue实现打印的两种方法：http://www.fly63.com/article/detial/2449?type=1

自己写的demo：

<template>
  <div>　
<div id="printTest" >

　　　　　　<p>明月照于山间</p>

　　　　　　<p>清风来于江上 </p>

　　　　</div>

　　　　<el-button v-print="'#printTest'">打印</el-button>
  </div>
</template>
<script>
export default {
  data() {
    return {
    };
  },
};
</script>
<style>
</style>
