Action Delegate between 2 applications

Question

Hi I'm creating a C# dll which is going to be called from another c# application. The dll task is to print documents. It will queue the requests & print the docs 1 after another. I would like the c# dll once it has printed a doc to notify the calling application. Then a message will be displayed on the user's screen. Trying to achieve this using Action Delegate but can't get it to work. What's the correct usage of Action Delegate in both the dll & main application in this example? Thanks
