WEB打印设置解决方案二（利用ScriptX.cab控件改变IE打印设置）

下载ScriptX.cab控件，修改codebase的值，默认下面的设置也可以。

页面加载控件：
<object id="factory" style="display:none" viewastext classid="clsid:1663ed61-23eb-11d2-b92f-008048fdd814" codebase="http://www.meadroid.com/scriptx/ScriptX.cab#Version=5,60,0,360"></object>

控件使用教本：
<script defer>
function SetPrintSettings() {
// -- advanced features ，未曾使用过，有待确认。
factory.printing.SetMarginMeasure(2) // measure margins in inches
factory.SetPageRange(false, 1, 3) // need pages from 1 to 3
factory.printing.printer = "HP DeskJet 870C"
factory.printing.copies = 2
factory.printing.collate = true
factory.printing.paperSize = "A4"
factory.printing.paperSource = "Manual feed"

// -- basic features 使用过
factory.printing.header = "This is MeadCo"
factory.printing.footer = "Advanced Printing by ScriptX"
factory.printing.portrait = false //方向，true
factory.printing.leftMargin = 1.0
factory.printing.topMargin = 1.0
factory.printing.rightMargin = 1.0
factory.printing.bottomMargin = 1.0

factory.printing.Print(false) //直接打印，true ，好像不起作用，总是弹出选择打印机窗口
factory.printing.PageSetup() //打印设置
factory.printing.Preview() //打印预览
}
</script>
