The OnPrintPage method allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
When a derived class calls the OnPrintPage method, it raises the PrintPage event by invoking the event handler through a delegate. For more information, see Handling and Raising Events.
When overriding OnPrintPage(PrintPageEventArgs) in a derived class, be sure to call the base class's OnPrintPage(PrintPageEventArgs) method so that registered delegates receive the event.
