        {
            ManagementEventWatcher watcher = WatchForProcessStart();
             while(true) watcher.WaitForNextEvent();
         }

        private static ManagementEventWatcher WatchForProcessStart()
        {
             string scope = @"\\.\root\CIMV2";
             string queryString = "SELECT TargetInstance FROM __InstanceCreationEvent WITHIN 5 WHERE TargetInstance ISA 'Win32_PrintJob'";

             ManagementEventWatcher watcher = new ManagementEventWatcher(scope, queryString);
             watcher.EventArrived += ProcessStarted;
             watcher.Start();
             return watcher;
         }

      private static void ProcessStarted(object sender, EventArrivedEventArgs e)
      {
          ManagementBaseObject targetInstance = (ManagementBaseObject)e.NewEvent.Properties["TargetInstance"].Value;
          targetInstance.Properties.Cast<propertydata>().ToList().ForEach(p => Console.WriteLine("{0}={1}", p.Name, p.Value));
      }
    }
}

推荐答案

使用 SetPrinter [ ^ ] API调用，结构 PRINTER_INFO_2 [ ^ ]并将pDatatype更改为EMF 1.008

Use the SetPrinter[^] API call, with the structure PRINTER_INFO_2[^] and change pDatatype to "EMF 1.008"
