Is it necessary for an image acquisition software/device to be TWAIN-compliant?
A. No, it is not at all necessary for an image acquisition software/device to be TWAIN-compliant, but it is RECOMMENDED as almost all image acquisition hardware and software follow the TWAIN specifications today. If an image acquisition software/device does not follow this standard you would have to scan an image with one application, save it and import the image into another application. But, if the image acquisition software/device is TWAIN compliant then the software can call up the scanner’s user interface without importing or opening other programs.
