Integrate document scanner with web application

I have a portable document scanner, which is Eloam's product. It has its own driver software which could do many things such as -Scan the image, -Convert it into PDF, create multiple PSD and also it has a capability to OCR.

So by the way, in short now my requirement is to scan, convert and save the image in web application. Is there any API? or another way to do it?
