You cannot print remotely but the following code is fine to work locally using DYMO Javascript framework.

            <script src="http://labelwriter.com/software/dls/sdk/js/DYMO.Label.Framework.latest.js"
            type="text/javascript" charset="UTF-8">   



            function GetDYMOPrinters()
            {   

                var printers = dymo.label.framework.getPrinters();
                if (printers.length == 0)
                throw "No DYMO printers are installed. Install DYMO printers.";
                var printerName = "";
                for (var i = 0; i < printers.length; ++i)
                {
                    var printer = printers[i];
                    if (printer.printerType == "LabelWriterPrinter")
                    {
                        printerName = printer.name;
                        break;
                    }
                }

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

            label.print("DYMO LabelWriter");
            }
     </script>

    </head>
    <body onload="  GetDYMOPrinters()">
         <form action="" method="post" id="DYMOLabel">
        <center>
        <h2>DYMO Label  Example</h2>
         <input type=button value="Get DYMO Printers" onClick="GetDYMOPrinters()">
     </center>
    </form>

To print a label directly from browser with DYMO without printer dialog you need

DYMO Label Framework JS SDK
DYMO Label Software (DLS).

You may download them here.

DLS needs to be installed on the computer where you have connected the DYMO device to. DLS comes with a DYMO Web Service that makes access possible through the browser.

Then, you can create a label XML file with DLS consisting of textareas and images.

Finally you can open the label XML file in JS with the Framework, and replace the textareas with text and the images with other images and then print it.

Here an example how to replace image from your labelXML with an PNG provided by an url:

// connect to printer
var printer = dymo.label.framework.getLabelWriterPrinters()[0].modelName;

// create label from XML file
var label = dymo.label.framework.openLabelXml(getLabelXml());

// load image from url and store as Base64
var image = dymo.label.framework.loadImageAsPngBase64("www.example.de/image.png");

// overwrite image "Image" from XML label with loaded image
label.setObjectText('Image', image);

// print it
label.print(printer);
