Putting printer URIs in WSDL files will be a maintenance nightmare, and
it seems a clear case of conflating interface and implementation to me.
Even the alternative I was talking about earlier, of having the URIs
identify "software", or simply a logical grouping of interfaces, would
have similar maintenance problems I think.

IMO, the simplest way to address this is to permit multiple interfaces
per service.
