Hi Gabe – sorry, missing background: My customer is using a Canon (I expect a DR-series) that has an onboard blank-page-discard. So when he runs it in duplex with blank-page-discard, it tosses out the blank backs of pages. Evidently this is not what customer wants… he wants to discard pages whose sides are both blank, and so we got wondering if there was a TWAIN way to do this, instead of just handling the blank-page-discard in software.
I think the concept is that if the application sees
Anyway – that’s what got me into this. I guess I’ll add some extinfo support to EZTwain and my other tools, and see if the Canon DR-series makes anything useful available.
