Specified by:

foundPrinter in interface DiscoveryHandler

Parameters:

printer - a discovered Link-OS™ printer.

discoveryFinished

public void discoveryFinished()

This method is invoked when discovery is finished.

Specified by:

discoveryFinished in interface DiscoveryHandler

discoveryError

public void discoveryError(String message)
