javascript - Javascript を使用してクライアント側の DYMO プリンターにラベルを印刷する

Question

複数回繰り返した後、次のコードがあります。どれも機能しません。これは、DYMO から直接の例と、ここに投稿された他の質問に基づいて取得しました。まだ何も機能していません。ボタンを押しても何の反応もありません。

<input id="btnUnitPrint" type="button" value="Print Unit Label" onclick = "printunitLabel()"/><br />
<input id="btnOrderPrint" type="button" value="Print Order Label" onclick = "printorderLabel()"/><br />
<script type="text/javascript">  
    function printunitLabel() {

        var printer = dymo.label.framework.getLabelWriterPrinters()[0].modelName;
        printerName = printer.name; 

        var label = DYMO.Label.Framework.Label.Open("UnitLabel.label");
        var company = document.getElementById('<%= txtcompany.Text %>').value;
        var customer = document.getElementById('<%= txtcustomer.Text %>').value;
        var serial = document.getElementById('<%= txtserial.Text %>').value;
        var unit = document.getElementById('<%= txtunit_manuf.Text + txtunit_model.Text %>').value;
        var warranty = document.getElementById('<%= ddlWarranty.Text %>').value;
        label.SetObjectText("lblcompany", company);
        label.SetObjectText("lblcustomer", customer);
        label.SetObjectText("lblserial", serial);
        label.SetObjectText("lblunit", unit);
        label.SetObjectText("txtWarranty", warranty);

        label.print(printerName);
    }  
    function printorderLabel() {

        var printer = dymo.label.framework.getLabelWriterPrinters()[0].modelName;
        printerName = printer.name;

        var label = DYMO.Label.Framework.Label.Open("OrderLabel.label");
        var company = document.getElementById('<%= txtcompany.Text %>').value;
        var customer = document.getElementById('<%= txtcustomer.Text %>').value;
        var order = document.getElementById('<%= txtorder_id.Text %>').value;
        label.SetObjectText("lblcompany", company);
        label.SetObjectText("lblcustomer", customer);
        label.SetObjectText("lblorder", order);
        label.Print(printer);

        label.print(printerName);
    } 
</script>
