The answer to what? Help with what? You would have to have some sort of a question or problem first.

The answer to the question "how to access parallel port?". With .NET; WCF and ASP.NET is of course irrelevant, but, frankly, this time, this is a real question. I even answered.

Okay... so the answer to the only question you actually asked is, yes it is possible. Possible for you? We would have no idea.

my problem is i need to control thru web.

It makes no special problem. What's the difference how you control it? Well, HTTP request gives you some request which requires the server site to do something with those ports. Server side looks at the request data and finds out what to do with the ports. This is no different from usual ASP.NET chores. If something here is unclear, you need to learn ASP.NET, maybe even starting from learning how Web works: HTTP servers, clients, HTTP protocols and other protocols. Most important thing here: embrace separation of concerns. Address each of concerns separately. If you have questions on ASP.NET, ask them; not need to related them to the ports.
