Sample Code:

            IntPtr pHandle;
            PRINTER_DEFAULTS defaults = new PRINTER_DEFAULTS();
            OpenPrinter(PrinterName, out pHandle, defaults);
            uint cbNeeded = 0;

            bool bRet = GetPrinter(pHandle, 2, IntPtr.Zero, 0, ref cbNeeded);
            if (cbNeeded > 0)
            {
                IntPtr pAddr = Marshal.AllocHGlobal((int)cbNeeded);
                bRet = GetPrinter(pHandle, 2, pAddr, cbNeeded, ref cbNeeded);
                if (bRet)
                {
                    PRINTER_INFO_2 Info2 = new PRINTER_INFO_2();
                    Info2 = (PRINTER_INFO_2)Marshal.PtrToStructure(pAddr, typeof(PRINTER_INFO_2));
                    // Now use the info from Info2 structure etc
                }
                Marshal.FreeHGlobal(pAddr);

            }

            ClosePrinter(pHandle);
