Print "raw" data using Print Spooler API

Question

I'm using windows spooler API in order to print a simple picture. In "TEXT" mode, my printer prints the picture as a text like it converts its data to char. So I've to use the "RAW" mode but nothing append in this case.
Here is the code :

void camgl::printShoot() {
HANDLE print_handle;
DOC_INFO_1 docinfo1;
DWORD bytes_written;

docinfo1.pDocName = (LPTSTR)L"Shot.jpg";
docinfo1.pOutputFile = NULL;
docinfo1.pDatatype = (LPTSTR)L"RAW";

BOOL bool1, bool2, bool3, bool4;

bool1 = OpenPrinter((LPTSTR)L"Canon MG6300 series Printer", &print_handle, NULL);
bool2 = StartDocPrinter(print_handle, 1, (LPBYTE)&docinfo1);

bool3 = StartPagePrinter(print_handle);
bool4 = WritePrinter(print_handle, (LPVOID)image->imageData, (DWORD)image->imageSize, &bytes_written);
EndPagePrinter(print_handle);
EndDocPrinter(print_handle);

ClosePrinter(print_handle); 
}

The variable "image" is defined like this :

• IplImage *image;

where IplImage is an OpenCV type of image.

I've tried to send a form-feed character to the printer but with no success:

int iFF = 0x0c;
WritePrinter(print_handle, (LPVOID)&iFF, (DWORD)sizeof(iFF), &bytes_written);

In both cases, the print queue displays a job that correspond to the printShoot() method, then the queue is cleared with no error and nothing is print by the printer.

WritePrinter only supports GDI printing.

Printing JPEG image requires more code. IF it is urgent, you can try to call Command line MS Paint to print the JPEG image

C:\Windows\System32\mspaint.exe C:\image.jpg /p
