    Hello,
    I’ve read Twain v 2.2 specification and I’m unable to find a way of detecting if device supports flatbed scanner. I understand that I can detect if it has feeder by checking if CapFeederEnabled capability is supported and can be set, but I need to check if device has also flatbed. Can this be done with Twain?
    Best regards

    Ok, now I know, so I’ll share – CapFeederEnabled IsSupported does not indicate that device has Feeder. Device can support this capability but only allow to set False value.
    You have to check possible values for this capability. Feeder is present/can be selected only if possible values contains True.
