Question

为了避免在Windows窗体应用程序零售单据上出现分页符，我遇到了麻烦，在打印单击按钮时，我首先生成HTML文件，然后在打印后使用Web浏览器控件生成HTML文件。我试图更改注册表设置，但可以避免页面剪切，如何停止页面剪切。

public void Print_Cash_sales()
    {


       var dir = @"D:\study\myslip.html";  // file location



       // MessageBox.Show(dir.ToString());



        //return;
        // Create a WebBrowser instance. 
        WebBrowser webBrowserForPrinting = new WebBrowser();

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

        // Set the Url property to load the document.
        webBrowserForPrinting.Url = new Uri(dir);



    }

public static void myWebBrowser_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
    {
        string pageSetupKey = "Software\\Microsoft\\Internet Explorer\\PageSetup";
        bool isWritable = true;
        string height = "1000";
        RegistryKey rKey = Registry.CurrentUser.OpenSubKey(pageSetupKey, isWritable);

        rKey.SetValue("margin_bottom", 0.10);
        rKey.SetValue("margin_left", 0.10);
        rKey.SetValue("margin_right", 0.10);
        rKey.SetValue("margin_top", 0.10);
        rKey.SetValue("footer", "");
        rKey.SetValue("header", "");
        rKey.SetValue("Print_Background", "yes");
        rKey.SetValue("SizeHeight", height.ToString(), Microsoft.Win32.RegistryValueKind.String);


        // Print the document now that it is fully loaded.
        ((WebBrowser)sender).Print();

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

        // myWebBrowser.ShowPrintPreviewDialog();
        // myWebBrowser.Print();
        rKey.SetValue("Print_Background", "no");

    }

这是html文件代码
