for my win 2000, I use PrintDLgEx,
the code like :

        HRESULT hResult;
        LPPRINTDLGEX pPDX = NULL;
        LPPRINTPAGERANGE pPageRanges = NULL;
        DEVMODE *dv;
        int nEscapeCode;
        TCHAR szTechnology[MAX_PATH] = TEXT("");

        pPDX = (LPPRINTDLGEX)GlobalAlloc(GPTR, sizeof(PRINTDLGEX));
        if (!pPDX)
        {
        //
        }

        pPageRanges = (LPPRINTPAGERANGE) GlobalAlloc(GPTR,
                          10 * sizeof(PRINTPAGERANGE));
        if (!pPageRanges)
        {
        //
        }

        pPDX->lStructSize = sizeof(PRINTDLGEX);
        pPDX->hwndOwner = GetDesktopWindow();;//hWnd;
        pPDX->hDevMode = NULL;
        pPDX->hDevNames = NULL;
        pPDX->hDC = NULL;
        pPDX->Flags = PD_RETURNDC | PD_COLLATE;
        pPDX->Flags2 = 0;
        pPDX->ExclusionFlags = 0;
        pPDX->nPageRanges = 0;
        pPDX->nMaxPageRanges = 10;
        pPDX->lpPageRanges = pPageRanges;
        pPDX->nMinPage = 1;
        pPDX->nMaxPage = 1000;
        pPDX->nCopies = 1;
        pPDX->hInstance = 0;
        pPDX->lpPrintTemplateName = NULL;
        pPDX->lpCallback = NULL;
        pPDX->nPropertyPages = 0;
        pPDX->lphPropertyPages = NULL;
        pPDX->nStartPage = START_PAGE_GENERAL;
        pPDX->dwResultAction = 0;

        hResult = PrintDlgEx(pPDX);

        if(hResult==S_OK )
        {

           dv=(LPDEVMODE)pPDX->hDevMode;
           char** Name=(char**)dv->dmDeviceName;
           file://ShowMessage(AnsiString((const char*)*Name));
           Edit1->Text=AnsiString((const char*)*Name);
           nEscapeCode = POSTSCRIPT_PASSTHROUGH;
           if( ExtEscape( pPDX->hDC, QUERYESCSUPPORT, sizeof(int),
                (LPCSTR)&nEscapeCode, 0, NULL ) > 0 )
           {
                 ShowMessage("Escape POSTSCRIPT_PASSTHROUGH is supported" );
                     return;
           }
            ShowMessage("Escape POSTSCRIPT_PASSTHROUGH is not supported" );
             // If it doesn't support GETTECHNOLOGY, we won't be able to
tell.
             nEscapeCode = GETTECHNOLOGY;
             if( ExtEscape( pPDX->hDC, QUERYESCSUPPORT, sizeof(int),
                (LPCSTR)&nEscapeCode, 0, NULL ) <= 0 )
             {
                  ShowMessage("Escape GETTECHNOLOGY is not supported" );
file://reaches here and exit,
                     return;
             }
  }


in the printer dialg, I choose the only printer, a network PS printer
hp4500,  hResult is OK,  but still fail to detect my PS printer, returned at
the position mentioned.
