Problems sending raw data to a printer

C++

Hey guys,

im am trying do send a pdf file to a multi-functional kyocera network printer (kyocera taskalfa 400ci) in my company. The printer is not shared over the network, but it is included as a local printer (kyocera printer driver, protocoll is raw, gdi enable) for security reasons. I can print files without any problems on my own.

Now I want to print automatically generated pdf files. I tried different solution for example like printing via adopbe reader but i dont want to use other software.

I found this example to send data directly to a gdi printer:

I used this code:

BOOL RawDataToPrinter(_WSTRING szPrinterName, LPBYTE lpData, DWORD dwCount) { 
    BOOL       bStatus = FALSE;
    HANDLE     hPrinter = NULL;
    DOC_INFO_1 DocInfo;
    DWORD      dwJob = 0L;
    DWORD      dwBytesWritten = 0L;

    // Open a handle to the printer. 
    bStatus = OpenPrinter( &szPrinterName[0], &hPrinter, NULL );
    if (bStatus) {
        // Fill in the structure with info about this "document." 
        DocInfo.pDocName = (LPTSTR)_T("test");
        DocInfo.pOutputFile = NULL;
        DocInfo.pDatatype = (LPTSTR)_T("RAW");

        // Inform the spooler the document is beginning. 
        dwJob = StartDocPrinter( hPrinter, 1, (LPBYTE)&DocInfo );
        if (dwJob > 0) {
            // Start a page. 
            bStatus = StartPagePrinter( hPrinter );
            if (bStatus) {
                // Send the data to the printer. 
                bStatus = WritePrinter( hPrinter, lpData, dwCount, &dwBytesWritten);
                EndPagePrinter (hPrinter);
            }
            // Inform the spooler that the document is ending. 
            EndDocPrinter( hPrinter );
        }
        // Close the printer handle. 
        ClosePrinter( hPrinter );
    }
    
	// Check to see if correct number of bytes were written. 
    if (!bStatus || (dwBytesWritten != dwCount)) {
        bStatus = FALSE;
    } else {
        bStatus = TRUE;
    }

    return bStatus;
}

long getFileSize(FILE *file) {
	long lCurPos, lEndPos;
	lCurPos = ftell(file);
	fseek(file, 0, 2);
	lEndPos = ftell(file);
	fseek(file, lCurPos, 0);
	return lEndPos;
}


bool sendFile(_WSTRING szFileName, _WSTRING szPrinterName) {
	BYTE *fileBuf;          // Pointer to our buffered data
	FILE *file = NULL;      // File pointer
	 
	// Open the file in binary mode using the "rb" format string
	// This also checks if the file exists and/or can be opened for reading correctly
	if ((file = _wfopen(szFileName.c_str(), L"rb")) == NULL)
		printf("Could not open specified file \n");
	else
		printf("File opened successfully \n");

	// Get the size of the file in bytes
	long fileSize = getFileSize(file);
 
	// Allocate space in the buffer for the whole file
	fileBuf = new BYTE[fileSize];

	// Read the file in to the buffer
	fread(fileBuf, fileSize, 1, file);
 
	if(RawDataToPrinter(szPrinterName, fileBuf, fileSize)) {
		wprintf(L"print successfull [%s] \n", szFileName.c_str());	
	} else {
		printf("print not successfull \n");	
	};
	 
	delete[]fileBuf;
	fclose(file);   
    return 0;
}

After every print job i get "print successfull". The printer seems to be find and it can also send data ( bStatus && (dwBytesWritten == dwCount --> TRUE), but nothing will be printed.

Any ideas where i should find the error?


Thanks for your help
