Now I'm using code below. But this code notifies me only when I plug in or out USB printer. But I need to get notified when printing occurs on USB printer. I am using c# and .netfx4.5.

Please help me, any suggestion would be highly appreciated!

What I have tried:

<pre>using LibUsbDotNet.DeviceNotify;
//...
public static IDeviceNotifier UsbDeviceNotifier = DeviceNotifier.OpenDeviceNotifier();

    private static void Main(string[] args)
    {
        // Hook the device notifier event
        UsbDeviceNotifier.OnDeviceNotify += OnDeviceNotifyEvent;

        // Exit on and key pressed.
        Console.Clear();            
        Console.WriteLine();
        Console.WriteLine("Waiting for system level device events..");
        Console.Write("[Press any key to exit]");

        while (!Console.KeyAvailable)
            Application.DoEvents();

        UsbDeviceNotifier.Enabled = false;  // Disable the device notifier

        // Unhook the device notifier event
        UsbDeviceNotifier.OnDeviceNotify -= OnDeviceNotifyEvent;
    }

    private static void OnDeviceNotifyEvent(object sender, DeviceNotifyEventArgs e)
    {
        // A Device system-level event has occured

        Console.SetCursorPosition(0,Console.CursorTop);

        Console.WriteLine(e.ToString()); // Dump the event info to output.

        Console.WriteLine();
        Console.Write("[Press any key to exit]");
    }
