Jaewoo,

The spool file's format varies depending on the app and the driver that are being used. You cannot count on spool files being in EMF, as they could also be RAW or XPS. That's not something you can control.

I'm not sure I understand your scenario, but I think you are adding a watermark to a print job using some service that is local on the machine and modifies the spool files before they are sent to the printer driver. This is not a scenario we support. You could build a solution where you do watermarking in the printer driver, though.

If you are still stuck, I'd recommend talking to Microsoft Support. http://support.microsoft.com.

Justin,

Thanks for your reply. I understand your means..

My scenario example :

Print Job -> Insert image watermark(JPEG) -> Print

But the WDK sample source have the only text base watermark..

Can I make the using WDK sample image watermark?

Thanks
