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);
