如何用javascript 指定打印机?

[skyover]

我使用控件是factory

[孟子E章]

<script defer>
function SetPrintSettings() {
// -- advanced features
factory.printing.SetMarginMeasure(2) // measure margins in inches
factory.printing.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
factory.printing.header = "This is MeadCo"
factory.printing.footer = "Advanced Printing by ScriptX"
factory.printing.portrait = false
factory.printing.leftMargin = 1.0
factory.printing.topMargin = 1.0
factory.printing.rightMargin = 1.0
factory.printing.bottomMargin = 1.0
}

function Print(frame) {
factory.printing.Print(true, frame) // print with prompt
}
</script>
