最近做项目需要打印快递单，在网上搜索了一下发现直接给出代码的比较少。
首先说一下js网页打印的几种方法：
1.window.print()
会弹出打印对话框
2.使用html 标签引入webbrowser控件
这种方式是其只兼容ie10以下的浏览器，其他浏览器不可使用
3.document.execcommand(”print”)
类似window.print()
**4.采用jquery插件
5.用浏览器打印第三方插件如lodpod等**
由于我这边不需要兼容ie10以下，而且个人不喜欢在react项目中引入jquery，同时嫌第三方插件太麻烦，最终选择window.print()，具体这几种方法区别大家可以去网上查一下，这类博客很多。
废话不多说，直接贴代码

通过css3 print控制打印样式，不需要打印的可以通过添加 class为noprint来隐藏

一开始在ff和chrome打印出来的会有细微差别，这是由于浏览器自带样式的影响，清除浏览器样式后基本没区别了还有就是chrome需要将浏览器设置里自定义字体中最小字体调到最低，不然会影响打印效果 ff这需要在打印里设置页头页脚为空白，不然打印的带页头页脚。
此外chrome打印出来的比ff清楚，这点原因我还没搞清楚。
贴两张打印预览，上面是chrome，下面是ff
