Reports in the Use Case Diagram

I have completed a couple of projects in the last two years using UML and I was wondering if readers could clarify the following?

When one has a number of reports in a system such as a management report and an anomily report (say). Does one specify a single Use Case in the Use Case Diagram called ‘Print Report’ or does one specify two: ‘Print Management Report’ and ‘Print Anomily Report’?

Further to the above, how does one break the Use Case down into an activity diagram (or scenario) for printing a report? It is a very straight forward thing that perhaps doesn’t warrent being a Use Case at all. If someone could point me to any useful examples I would be grateful.
