Printing google maps in a webbrowser control - won't show directions line

Question

Using IE 11, Windows 8.1.

I'm plugging in the following into a windows form application:

 var html = "" +
               "" +
               "
View Larger Map";

        webBrowser1.DocumentText = (html);

Now I want to print this as seen, but it doesn't show the directions lines when I got to printpreview

 private void button1_Click(object sender, EventArgs e)
    {
        this.webBrowser1.ShowPrintPreviewDialog();           
    }

I have tried different browser emulations and still no way to print the direction lines in google maps. IE6 - 11 with no luck.

 SetBrowserFeatureControlKey("FEATURE_BROWSER_EMULATION", fileName, GetBrowserEmulationMode());

     public static UInt32 GetBrowserEmulationMode()
    {
        int browserVersion = 7;
        using (var ieKey = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\Internet Explorer",
            RegistryKeyPermissionCheck.ReadSubTree,
            System.Security.AccessControl.RegistryRights.QueryValues))
        {
            var version = ieKey.GetValue("svcVersion");
            if (null == version)
            {
                version = ieKey.GetValue("Version");
                if (null == version)
                    throw new ApplicationException("Microsoft Internet Explorer is required!");
            }
            int.TryParse(version.ToString().Split('.')[0], out browserVersion);
        }

        // Internet Explorer 10. Webpages containing standards-based !DOCTYPE directives are displayed in IE10 Standards mode. Default value for Internet Explorer 10.
        UInt32 mode = 11000;

        switch (browserVersion)
        {
            case 7:
                // Webpages containing standards-based !DOCTYPE directives are displayed in IE7 Standards mode. Default value for applications hosting the WebBrowser Control.
                mode = 7000;
                break;
            case 8:
                // Webpages containing standards-based !DOCTYPE directives are displayed in IE8 mode. Default value for Internet Explorer 8
                mode = 8000;
                break;
            case 9:
                // Internet Explorer 9. Webpages containing standards-based !DOCTYPE directives are displayed in IE9 mode. Default value for Internet Explorer 9.
                mode = 9000;
                break;


            case 10:
                // Internet Explorer 9. Webpages containing standards-based !DOCTYPE directives are displayed in IE9 mode. Default value for Internet Explorer 9.
                mode = 10000;
                break;

            default:
                // use IE10 mode by default
                break;
        }

        return mode;
    }

Can anyone help me find out why this doesn't print the directions lines? Keep in mind, directly plugging in this html into a .html file and opening with IE, will show the directions lines. But they do not print.

Update

Using IE, you can plug in the following into a document with extension html.


View Larger Map

This will print everything correctly in firefox. I have tested this out on multiple printers.

This does not print correctly in IE. I have tried the following:

Any ideas on how to get the lines to show up?
