It's possible to do but you cannot do it using only javscript in the browser. Code running in the browser has no access to anything on the client. No access to the file system, display, scanners, ... nothing. All it can do external to the browser is talk to web servers. But, there is no restriction on where that web server has to be running.

You have to write a service application to be installed on the client. This service has two sides to it, the first being an interface to the scanner, doing all of the work of controlling the scanner and managing the resulting files on the client machine.

The other side of the service is a web server, exposing a controlling interface that can be used from the javascript code in your web page. This interface would be a WebAPI or similar. The functions you expose would have to be everything the javascript code is going to need to control the scanner, through the service.
