Printer Driver --- Is there a way I can know if "Print to file" is been checked or not?

Hi all,

In my Windows XP/2k printer driver(user mode), I need to check if "Print to
file" is been checked or not.
I did some test that checking
DrvDocumentEvent->DOCUMENTEVENT_STARTDOCPRE->pDocInfo->lpszDocName,
but I can not get the inf. about "Print to file".

If "Print to file" is been checked, I must send data to my printer only.
If "Print to file" is not been checked, I need read some inf from my
printer, then send data to it.

Is there a way I can know if "Print to file" is been checked or not?

Thanks a lot!

Sorry for my wrong explanation.

If "Print to file" is been checked, the data is been sent to the file.
If "Print to file" is not been checked, I need read some inf from my
printer, then send data to it.

Thanks a lot.

I found the way to confirm Is there a way I can know if "Print to file" is
been checked or not?
Checking DrvDocumentEvent->DOCUMENTEVENT_STARTDOCPRE->pDocInfo->lpszOutput

If "Print to file" is been checked, lpszOutput is the file name.
If "Print to file" is not been checked, lpszOutput is PortName(example:
LPT1)

Thanks
