i m having a set of files(.tiff) stored in a folder on my hard disk
   i need to send them to the printer attached to the system one by one
   i have to use c++ or VC++
   but there should not be any user interaction as it is going to be implemented as a program.
   CPrintDialog will not work as it needs user interaction
   any other method please suggest

you could send raw data bytes to a printer as you could see in the MSDN.

"
 BOOL RawDataToPrinter(LPSTR szPrinterName, LPBYTE lpData, DWORD dwCount)
   {
     HANDLE     hPrinter;
     DOC_INFO_1 DocInfo;
     DWORD      dwJob;
     DWORD      dwBytesWritten;

     // Need a handle to the printer.
     if( ! OpenPrinter( szPrinterName, &hPrinter, NULL ) )
       return FALSE;

     // Fill in the structure with info about this "document."
     DocInfo.pDocName = "My Document";
     DocInfo.pOutputFile = NULL;
     DocInfo.pDatatype = "RAW";
     // Inform the spooler the document is beginning.
     if( (dwJob = StartDocPrinter( hPrinter, 1, (LPSTR)&DocInfo )) == 0 )
     {
       ClosePrinter( hPrinter );
       return FALSE;
     }
     // Start a page.
     if( ! StartPagePrinter( hPrinter ) )
     {
       EndDocPrinter( hPrinter );
       ClosePrinter( hPrinter );
       return FALSE;
     }
     // Send the data to the printer.
     if( ! WritePrinter( hPrinter, lpData, dwCount, &dwBytesWritten ) )
     {
       EndPagePrinter( hPrinter );
       EndDocPrinter( hPrinter );
       ClosePrinter( hPrinter );
       return FALSE;
     }
     // End the page.
     if( ! EndPagePrinter( hPrinter ) )
     {
       EndDocPrinter( hPrinter );
       ClosePrinter( hPrinter );
       return FALSE;
     }
     // Inform the spooler that the document is ending.
     if( ! EndDocPrinter( hPrinter ) )
     {
       ClosePrinter( hPrinter );
       return FALSE;
     }
     // Tidy up the printer handle.
     ClosePrinter( hPrinter );
     // Check to see if correct number of bytes were written.
     if( dwBytesWritten != dwCount )
       return FALSE;
     return TRUE;
   }

Hope this helps!

Good luck!
