采用下面的代码可以打开打印机属性对话框，但是用户在该对话框中进行了设定后，新的设定值并没有保存到系统中。如何才能保存用户的设定阿？
string printerName = _document.PrinterSettings.PrinterName;

if (printerName != null && printerName.Length > 0)
{
IntPtr pPrinter = IntPtr.Zero;
IntPtr pDevModeOutput = IntPtr.Zero;
IntPtr pDevModeInput = IntPtr.Zero;
IntPtr nullPointer = IntPtr.Zero;

OpenPrinter(printerName, ref pPrinter, ref nullPointer);

int iNeeded = DocumentProperties(this.Handle, pPrinter, printerName, ref pDevModeOutput, ref pDevModeInput, 0);
pDevModeOutput = System.Runtime.InteropServices.Marshal.AllocHGlobal(iNeeded);
DocumentProperties(this.Handle, pPrinter, printerName, ref pDevModeOutput, ref pDevModeInput, 4);

ClosePrinter(pPrinter);
}

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() });

}
