On the client(user) of the Web application,there is a scanner which
is connected to the client machine and when the user puts a document (such as a paper containing text and images) on the surface of the scanner, he can click on a button on a form of the Web application and this click must trigger the scanning process and the file resulting of the scanning must be placed in a folder of the client machine (let's say this folder is D:\Images).
I don't know how I can implement this.
Please , how can I solve this problem?
Thanks you in advance for your answers.
