部署时不会打印带有Web浏览器控件的Windows服务

我开发了一个Windows服务，每x次检查一个目录，如果存在html文件，它们会被发送到打印机 .
在我的电脑上一切正常，但当应用程序部署在服务器PC上时，它不会打印 .
对于实现，我使用此链接作为参考：https://limbioliong.wordpress.com/2014/07/21/using-the-webbrowser-control-to-print-documents/ .
通过日志记录，我知道事件ie.PrintTemplateInstantiation被调用 . 之后，不再记录任何内容，没有错误 . 可能有什么不对？

所有相关代码：

Thread thread = new Thread(PrintDocument);
  thread.SetApartmentState(ApartmentState.STA);
  thread.Start();

private void PrintDocument()
  {
     try
     {
        var printJob = _printJobs.First(x => !x.Printed);
        new Print.Print().StartDocumentPrint(_printerName, printJob, PrintFinished);
     }
     catch (Exception ex)
     {
        // Some logging
     }
   }

public void StartDocumentPrint(string pname, PrintJob file, Action<PrintJob> finished)
  {
     _file = file;
     _finishedAction = finished;

     try
     {
        // Create a WebBrowser instance. 
        var 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(file.File);

        Application.Run();
     }
     catch (Exception ex)
     {
        // Logging
     }
  }

private void PrintDocument(object sender, WebBrowserDocumentCompletedEventArgs e)
  {
     var logService = DependencyResolver.Container.Resolve<ILogService>();
     WebBrowser wb = sender as WebBrowser;

     try {
        SHDocVw.InternetExplorer ie = (SHDocVw.InternetExplorer)(wb.ActiveXInstance);

        ie.PrintTemplateInstantiation +=
          new SHDocVw.DWebBrowserEvents2_PrintTemplateInstantiationEventHandler(IE_OnPrintTemplateInstantiation);

        ie.PrintTemplateTeardown +=
          new SHDocVw.DWebBrowserEvents2_PrintTemplateTeardownEventHandler(IE_OnPrintTemplateTeardown);

        ie.PutProperty("WebBrowserControl", (object)wb);

       wb.Print();
     }
     catch (Exception ex)
     {

        // Logging
     }
  }

private static void IE_OnPrintTemplateInstantiation(object pDisp)
  {
     // Logging
  }

private static void IE_OnPrintTemplateTeardown(object pDisp)
  {
     // Logging

     _finishedAction.Invoke(_file);

     SHDocVw.IWebBrowser2 iwb2 = pDisp as SHDocVw.IWebBrowser2;
     WebBrowser wb = (WebBrowser)(iwb2.GetProperty("WebBrowserControl"));

     wb.Dispose();

     Application.ExitThread();  
  }
