A handle to a DEVMODE structure.
DEVMODE structures are device specific. Copying a DEVMODE structure from one System.Drawing.Printing.PrinterSettings to a System.Drawing.Printing.PrinterSettings for a different printer is not supported. When you are done with the handle that is created through this method, you must deallocate it yourself by calling the native Win32 GlobalFree method. When you call this method, you pass as a parameter the return value from the PrinterSettings.GetHdevmode method.
