Um, is the scanner on the client or the server? You can't run code
(beyond JavaScript etc) on the client.

If you have reasonable knowledge about the clients (i.e. a corporate
LAN), then you can do this using a client-side OCX hosted on the page
(OBJECT tag) that talks to the scanner (it would also need to talk
directly to the server over HTTP - not the HTML page). I've use
ImageMan TWAIN to do this in the past (for a document management
system), but any similar (including perhaps WIA) would suffice.

This will only work in IE, and would require the OCX to either be
signed, or to be pre-installed on the client (the latter is easier);
and (in either event) marked safe-for-activation, safe-for-scripting.
(or whatever the keywords are; it has been about 5 years since I did
this...).

If I was doing this today, I would perhaps write a smart-client (exe)
that hosts a WebBrowser to show the existing app, and perhaps makes
scanning available via the "external" object(ObjectForScripting or
some-such).

I've use ImageMan TWAIN to do this in the past
To clarfy - I wrote an OCX (using VB6 at the time) that *internally*
used ImageMan TWAIN and provided a UI etc; I didn't host ImageMan
TWAIN on the page itself.
