vue打印功能详解
安装Print包
npm install vue-print-nb --save
main.js全局注册
import Print from 'vue-print-nb'
Vue.use(Print);

使用
用v-print指定需要打印的div容器，本次叫printTest。
最好使用行内样式，使用组件库部分样式可能不能生成。

       <div id="printTest" >
           <p>锄禾日当午</p>
　　　　　　<p>汗滴禾下土 </p>
　　　　　　<p>谁知盘中餐</p>
　　　　　　<p>粒粒皆辛苦</p>
　　　　</div>
　　　　<button v-print="'#printTest'">打印</button>
