打印WebBrowser控件内容

我对 .NET 打印完全陌生。我想打印在 WebBrowser 控件中显示的页面。我怎么做？

MSDN 有一篇关于此的文章，但是他们的代码示例演示了如何使用 WebBrowser 控件打印网页而不显示它。 :

如何：使用 Web 浏览器控件进行打印

C# 代码：

private void PrintHelpPage()
{
    // Create a WebBrowser instance. 
    WebBrowser webBrowserForPrinting = new WebBrowser();

    // Add an event handler that prints the document after it loads.
    webBrowserForPrinting.DocumentCompleted +=
        new WebBrowserDocumentCompletedEventHandler(PrintDocument);

    // Set the Url property to load the document.
    webBrowserForPrinting.Url = new Uri(@"\\myshare\help.html");
}

private void PrintDocument(object sender,
    WebBrowserDocumentCompletedEventArgs e)
{
    // Print the document now that it is fully loaded.
    ((WebBrowser)sender).Print();

    // Dispose the WebBrowser now that the task is complete. 
    ((WebBrowser)sender).Dispose();
}
