                pDevModeOutput = System.Runtime.InteropServices.Marshal.AllocHGlobal(iNeeded);
                DocumentProperties(this.Handle, pPrinter, printerName, ref pDevModeOutput, ref pDevModeInput, 4);

var query = new ManagementObjectSearcher("SELECT * FROM Win32_Printer");
var printers = query.Get();
foreach (var each in printers) { Console.WriteLine(each["name"]); }if (xpsprinter != null) {
xpsprinter.InvokeMethod("SetDefaultPrinter", new object[] { xpsprinter["name"].ToString() });
}
