Hi Walter,

Youi should only return one or more ".../ipp/print" URIs for Print service
and one or more ".../ipp/faxout" URIs for FaxOut service.

Only the *future* IPP System Service (that Mike and I are writing) will
show in "configured-printers" a list of all services with service type,
URI, UUID, etc.

Cheers,
- Ira
