            var label = DYMO.Label.Framework.Label.Open("MyText.label");
            label.SetObjectText("NameTxt", "John Smith");

            alert(" Testing 2");   // Here this alert also not working .
            label.print("DYMO LabelWriter 310");
            }
     </script>

    </head>
    <body onload="OnLoad()">
         <form action="" method="post" id="DYMOLabel">

        <h2>DYMO Label  Example</h2>
         <input type=button value="Get DYMO Printers" onClick="GetDYMOPrinters()">
     </center>
    </form>




    </body>
</html>

但是这里什么都不会发生，我需要导入或包含任何东西吗？请给点建议..

【问题讨论】：

当我运行你的代码时，它显示了 Uncaught ReferenceError: DYMO is not defined sample_dymo.html:40 GetDYMOPrinters sample_dymo.html:40 onclick

标签： javascript printing barcode-printing

【解决方案1】：

您用于嵌入“DYMO.Label.Framework.latest.js”的<script>-标签位于另一个脚本标签中。将其移出，您的函数应该会运行：

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/1999/REC-html401-19991224/loose.dtd">

    <!-- LabelWriter-API first -->
    <script src="http://labelwriter.com/software/dls/sdk/js/DYMO.Label.Framework.latest.js"></script>
    <!-- your script second -->
    <script>
     ...

【讨论】：

谢谢，我可以使用这些功能...您知道如何调用打印机来打印一些文本或标签吗？我已经安装了所有 Dymo 的东西。
我搜索了一下，找到了这个示例页面：labelwriter.com/software/dls/sdk/samples/js/… 看一下 PreviewAndPrintLabel.js，基本上它加载了一个标签-XML 设置了地址文本并打印出来。
非常感谢，我会处理的。

【解决方案2】：

这是我打印多个标签的代码。为了您的帮助，我添加了 cmets。请通过这个，如果你有任何疑问，问我。我无法在此处包含我的 HTML 供您参考。

我正在设置一个 XML 模板来打印我的 Dymo 标签。我认为它正在打印作为地址的条形码。如何设置它打印指定的值，例如可以传递给打印函数的 ID？
你应该将该值传递到文本区域（这里：#labelPrint）
