FUJITSU TWAIN 32 Scanner Driver

2. TWAIN

2.1. TWAIN

TWAIN is the specification that defines the standard software protocol and application programming interface (API) for data exchange between a software application program and an image input device such as the image scanner.

[TWAIN development background]

In the past, development of a new scanner inevitably required the development of a compatible driver and a sample (demonstration) program exclusively designed for the new scanner. As the scanner is upgraded, the driver may need to be upgraded as well to maintain its compatibility with the upgraded scanner. Therefore, the use is most likely to be restricted to one specific scanner model to avoid the complication of learning new operation methods and replacing the peripheral driver, etc., involved in scanner replacement.

In view of the incompatibility among different scanners and peripheral equipment and the accompanying inconvenience, there was a demand for standardization of the related hardware and software, and TWAIN was established as a result.

The user may now choose among all the input devices and software (driver or application programs) conforming to the TWAIN standard, and configure a most suitable system for himself, without being restricted to the products of a certain series or a certain manufacturer.
