Hello,

I am trying to perform Twain scanning using the twain_32.dll, but no luck. Whatever solutions I have got call the dll GUI.

I want to perform scanning by passing custom settings to the scanner for every scan. For eg. In duplex I want to scan the Front side in color & Back side in Grayscale.
OR
Scan every Alternate page as Color and B/W

The combination can be anything. I've tried & and succeeded using WIA but it limited me to a certain extent.
Can anyone help me with how to proceed using TWAIN and without displaying the GUI.
I am open to options where a communication to Twain Connection Manager is established & commands are passed.

Thank you in advance
