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

@media print{  body, h1, h2, h3, h4, h5, h6, hr, p, blockquote, dl, dt, dd, ul, ol, li, pre, form, fieldset, legend, button, input, textarea, th, td { margin:0; padding:0; }  body, button, input, select, textarea { font:12px/1.5 arial,"黑体", /5b8b/4f53; }  h1, h2, h3, h4, h5, h6{ font-size:100%; }  address, cite, dfn, em, var { font-style:normal; }  code, kbd, pre, samp { font-family:couriernew, courier, monospace; }  small{ font-size:12px; }  ul, ol { list-style:none; }  a { text-decoration:none; }  a:hover { text-decoration:underline; }  sup { vertical-align:text-top; }  sub{ vertical-align:text-bottom; }  legend { color:#000; }  fieldset, img { border:0; }  button, input, select, textarea { font-size:100%; }  table { border-collapse:collapse; border-spacing:0; }  .no-print{    display:none;  }  @page{    size: 100mm 150mm;    margin: 1.75mm;  }  #printPage {    width: 96mm;    height: 146mm;    position: relative;    border: 1px dotted #000000;    box-sizing: border-box;  }  #printPage span{    margin-left: 2mm;  }  .left {    border-left: 1px dotted #000000;    border-right: 1px dotted #000000;    border-bottom: 1px dotted #000000;    left: 0;  }  .right {    border-right: 1px dotted #000000;    border-bottom: 1px dotted #000000;    /*right: 0;*/  }  .deviation{    margin-left: 2mm;  }  #emsType{    width: 40mm;    height: 14mm;    position: absolute;    top: 0;    padding-top: 6mm;    font-size: 20px;    border-top: 1px dotted #000000;  }  #barcode{    width: 56mm;    height: 20mm;    position: absolute;    top: 0;    left: 40mm;    border-top: 1px dotted #000000;  }  #sender{    width: 46mm;    height: 15mm;    font-size: 12px;    position: absolute;    top: 20mm;  }  #area{    width: 50mm;    height: 15mm;    position: absolute;    top: 20mm;    left: 46mm;  }  #recipient{    width: 96mm;    height: 17mm;    position: absolute;    left: 0;    top: 35mm;    font-size: 12px;  }  #pay{    width: 40mm;    height: 14mm;    position: absolute;    top: 52mm;    font-size: 12px;  }  #delivers{    width: 56mm;    height: 14mm;    position: absolute;    top: 52mm;    left: 40mm;    font-size: 12px;  }  #order{    width: 96mm;    height: 20mm;    position: absolute;    left: 0;    top: 66mm;    font-size: 12px;  }  #divide{    width: 96mm;    height: 4mm;    position: absolute;    left: 0;    top: 86mm;  }  #number{    width: 96mm;    height: 15mm;    position: absolute;    left: 0;    top: 90mm;    font-size: 12px;  }  #send{    width: 40mm;    height: 17mm;    position: absolute;    top: 105mm;    font-size: 12px;  }  #pickup{    width: 56mm;    height: 17mm;    position: absolute;    top: 105mm;    left: 40mm;    font-size: 12px;  }  #remark{    width: 68mm;    height: 17mm;    position: absolute;    top: 122mm;    font-size: 12px;  }  #net{    width: 68mm;    height: 7mm;    position: absolute;    top: 139mm;    font-size: 12px;  }  #QRCode{    width: 28mm;    height: 24mm;    position: absolute;    top: 122mm;    left: 68mm;  }  #note{    font-size: 6px;  }}

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
