No, no error, there is no address for the lp service.  The address
used is that of the listener service.  The remote system asks the
listener for a connection to the lp service.  The listener has a "well
know address" that other systems will use to connect to the local
system, then request a local service; in this case lp.

If you look a little further in the SAG, you'll see the entry for
accepting connections from systems using the lpr/lpd service.  Lpd
expects to connect to a specific address, so the -A option is used to
provide the address that lpd wants.
