TWAIN is a high-level specification for an interface to
scanners (or similar devices). Therefore the specific appearance
to the user may vary between different twain scanners. The
standard just describes the way of calling this interface from
programs and how to get at the scan results (from a program).

The TWAIN specification is freely available on the web (Warning:
it is more than 400 pages!). This however, does not help us
towards using DOS scanners, as the TWAIN standard defines the
needed API calls only for Windows and Macintosh. So, before we
will ever see DOS TWAIN Scanners, the TWAIN committee first has
to specify a DOS API at all!

(When I had to interface to TWAIN scanners from our DOS products,
I wrote a little windows program [controlled by a command file
from the DOS box] which uses the standard Win-API for TWAIN.
So, it can be done from DOS already now, but currently only in
the DOS box of Win3.x/9x/NT and not in a pure DOS environment.)

Actually, the original meaning was "Technology without an
important name".

The reason is historical: When the TWAIN committee started its
work, several companies attempted to get their already existing
proprietory scanner interfaces into the emerging standard - or at
least its name. To avoid wasting time with "name wars", the
committee members decided that they first wanted to produce the
specification and then give it a name. To express this clearly,
they used the placeholder "technology without an important name"
and as a joke abbreviated it "TWAIN".

However, when the specification finally was complete, everybody
had gotten so used to "TWAIN" that they did not want to change it
anymore!

But, of course, they could not leave "technology without an
important name" as the official title for an established industry
standard. So, formally, the TWAIN home page states in its FAQ
that currently there is no official "long form" for TWAIN. But
the above story is how it all came about ...
