What is the significance of the TWAIN interface standard?
1. Non-Windows applications use the TWAIN interface standard to emulate a Windows interface.
2. >>Scanner hardware device drives must be written to the TWAIN interface standard.
3. The TWAIN interface standard is responsible for optical character recognition (OCR).
4. The TWAIN interface standard enables applications to directly control a scanner.
Explanation : The TWAIN interface standard enables imaging applications to directly control a scanner and scan images into the application. The term comes from the phrase "never the twain shall meet" and is designed to make it easier to use scanners and other imaging devices.
The TWAIN interface standard is not a hardware device driver standard. Most, but not all, scanners support the TWAIN interface standard. Many manufacturers include interface software that supports more advanced features than those supported by the TWAIN interface standard.
The TWAIN interface standard is not related to OCR applications except as a way of importing images directly into an application at supports OCR functionality. OCR software is able to recognize and extract character data from a scanned image.
The TWAIN interface standard is not related to Windows interface emulation. It is related specifically to imaging applications.
Objective: Printers and Scanners
