TWAIN is a software interface that was used between imaging hardware (scanners) and a computer operating system. As desktop publishing became the new more efficient way of document publishing and image scanning hardware became available a software interface needed to be developed to facilitate this. The resulting toolkit that was developed was named TWAIN because the developers could come up with a cool name, thus it got called Toolkit Without An Interesting Name (TWAIN). Imaging devices now have individual device drivers per operating system.
