Printer defines an interface for outputting information about status of resources. Different implementations allow output formats tailored to different use cases.
type Printer interface {
// Print tells the printer to start outputting data. The stop parameter
// is a channel that the caller will use to signal to the printer that it
// needs to stop and shut down. The channel returned can be used by the
// printer implementation to signal that it has outputted all the data it
// needs to, and that it has completed shutting down. The latter is important
// to make sure the printer has a chance to output all data before the
// program terminates.
