一个需求需要采用横向打印，目前采用IE自身的打印功能（WebBrowser.ExecWB控件）很难进行横向设置，默认需要调用document.all.WebBrowser.ExecWB(8,1);打开打印设置对话框进行人工设置，颇为不方便，本次采用ActiveX控件，也即第三方的ScriptX控件进行横向设置。
ScriptX基本功能免费，但高级功能是收费的，下面我就把最近在项目中使用ScriptX的经验总结一下。
1. 首先把ScriptX.cab放在一个目录下面，比如根目录
2. 目前html5 doc需要把object放在head之外
引入如下
...
</head>
<object id="factory" style="display: none" viewastext classid="clsid:1663ed61-23eb-11d2-b92f-008048fdd814"
codebase="ScriptX.cab#Version=5,60,0,360"></object>
<body>
...
3. 设置打印属性
function InitPrinterSetting() {
factory.printing.header = "";//页眉
factory.printing.footer = "";//页脚
factory.printing.leftMargin = 1.0;//左边距
factory.printing.topMargin = 1.3;//上边距
factory.printing.rightMargin = 1.0;//右边距
factory.printing.bottomMargin = 1.3;//下边距
factory.printing.portrait = false;//打印方向，true:纵向.false:横向
}
4. 如下style用于去除打印
<style media="print">
.Noprint{display:none;} <!--用本样式在打印时隐藏非打印项目-->
.PageNext{page-break-after: always;} <!--控制分页-->
</style>
