Remarks
This is a convenience method that can be used as an alternative to the other discovery methods (e.g. multicast).
This method will invoke the FoundPrinter(DiscoveredPrinter) method for each printer that is found during discovery. DiscoveryFinished will be invoked when the discovery is finished and DiscoveryError(String) will be invoked when any errors are encountered during discovery. When DiscoveryError(String) is invoked, the discovery will be canceled and DiscoveryFinished will not be invoked.
If a printer responds to the discovery request more than once, the FoundPrinter(DiscoveredPrinter) method will only be invoked on the first occurrence.
