Hi,
it might be an already answered question but I couldn't find it. It is possible to use multiple twain devices at once. In other words is it possible to scan on two ore more scanners simultaneously?

Thanks in advance for your reply.

Hello,

You can use only one device per one GdPictureImaging object because you need to select/open the required device/source:
TwainOpenSource
TwainSelectSource
So I would say using multiple GdPictureImaging objects you can open more devices.
