RFC 1179 states that LPD connections should originate from ports 721-731. I know of only one LPD, MVS TCP/IP Print Services, that enforces this. I think it's fine to have an LPD option or options that allows print to come from non-standard ports, e.g. < 1024 or any port, however should LPR/LPD conform to the standard? Having said that, all UNIX systems I've worked on, except for AIX, do not completely adhere to the RFC, hence printing from non-conforming systems would definitely break.
