将浏览器内容打印为横向

Question

I need to print document from WebBrowser control as landscape (without showing PrintPreview and changing default printer page orientation). 我需要从WebBrowser控件以横向打印文档（不显示PrintPreview并更改默认打印机页面方向）。

I've tried: 我试过了：

TemplatePrinter Here's my template template.html: TemplatePrinter这是我的模板template.html：

 <HTML XMLNS:IE> <HEAD> <?IMPORT NAMESPACE="IE" IMPLEMENTATION="#default"> <TITLE>Landscape</TITLE> </HEAD> <BODY> <IE:TEMPLATEPRINTER id="Printer"/> <SCRIPT Language="JavaScript"> Printer.orientation="landscape"; </SCRIPT> </BODY> </HTML>

And I try to use it: 我尝试使用它：

 mshtml.IHTMLDocument2 doc = wbReport.Document.DomDocument as mshtml.IHTMLDocument2; doc.execCommand("print", false, "template.tpl");

Create reg key "orientation" with value "2" in HKCU\\Software\\Microsoft\\Internet Explorer\\PageSetup 在HKCU \\ Software \\ Microsoft \\ Internet Explorer \\ PageSetup中创建值为“ 2”的注册表项“ orientation”

Add style like: 添加样式：

 <style type="text/css" media="print"> @page { size: landscape; margin: 2cm; } </style>

But I still print my html as portrait. 但是我仍然将html打印为肖像。 Maybe there is better solution to print html as landscape or I have some mistakes when using TemplatePrinter? 也许有更好的解决方案将html打印为横向，或者在使用TemplatePrinter时出现一些错误？

After messing around with the registry, attempting to use print templates in IE and various other methods (none of which worked) i've produced a somewhat hacky workaround. 在弄乱注册表之后，尝试在IE中使用打印模板和其他各种方法（均无效），我产生了一个有点怪异的解决方法。

I've extended the WebBrowser control and created a new print preview method inside which I have methods to pass the ALT+L key combination to enable landscape view: 我扩展了WebBrowser控件，并创建了一个新的打印预览方法，在其中，我有一些方法可以传递ALT + L组合键以启用横向视图：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace YourProjectNamespace
{
    class ExWebBrowser : WebBrowser
    {
        void setLandscapeTimer_Tick(object sender, EventArgs e)
        {
            SendKeys.SendWait("%L");
            this.ProcessDialogKey(Keys.Alt & Keys.L);
            SendKeys.Flush();
        }

        public void _ShowPrintPreviewDialog()
        {
            this.ShowPrintPreviewDialog();
            this.Focus();

            Timer setLandscapeTimer = new Timer();
            setLandscapeTimer.Interval = 500;
            setLandscapeTimer.Tick += new EventHandler(setLandscapeTimer_Tick);
            setLandscapeTimer.Start();
        }
    }
}

All you need to do is simply instantiate the object, load a document as with the standard WebBrowser and call _ShowPrintPreviewDialog. 您需要做的只是简单地实例化对象，像使用标准WebBrowser一样加载文档并调用_ShowPrintPreviewDialog。

Note you may want to stop the timer once the landscape view has been set. 请注意，一旦设置了风景视图，您可能想停止计时器。
