May I know how can I do internet printing through ASP.Net ?

Essentially the situation is this. There is a printer which is connected to a machine where internet printing protocol is installed and configured. I need to upload a document to a server. This I could do. Then I need to make the document print using the above printer. I need to somehow trigger a printing action on the printer where internet printing protocol is installed. But I don't know how.

Could anybody please suggest some ASP.Net code / URL ?

What is your internet printing protocol? Do you just want to send some text to a printer cross the internet? Please give more infomation.
