Setting Which TWAIN Specification Version to Use

LEADTOOLS Twain toolkits support both the TWAIN 1.9 and the TWAIN 2.x specifications. By default LEADTOOLS Twain starts TWAIN 2.x. If that fails it will try to start TWAIN 1.9. It is also possible to specify which version to use. To do so, call the TwainSession.SetVersion method and pass "Version1" to use version 1.9, and "Version2" to use version 2.x. More information about the different specifications follows.
