If you look at the source code for TPrinterSetupDialog and
TPrintDialog, you can see how they both use the DEVMODE and DEVNAMES
structures to set the PrinterIndex.  Both dialogs call the
TPrinter::SetPrinter() method.  For example (translated from the
dialog source code):

    void __fastcall SetPrinter(HANDLE DeviceMode, HANDLE DeviceNames)
    {
        DEVNAMES *DevNames = (DEVNAMES*) GlobalLock(DeviceNames);
        try
        {
            Printer()->SetPrinter(
                ((char*)DevNames) + DevNames->wDeviceOffset,
                ((char*)DevNames) + DevNames->wDriverOffset,
                ((char*)DevNames) + DevNames->wOutputOffset,
                (int)DeviceMode);
        }
        __finally
        {
            GlobalUnlock(DeviceNames);
            GlobalFree(DeviceNames);

            // TPrinter takes ownership of the DeviceMode so do not
free it...
        }
    }
