<html> I wrote the sentences that you are asking about.  I tried to pick words that would be unambiguous. The intention is that IPP software must be able to listen on port 631 and may be able to listen on other ports. If such software allows an administrator to configure the ports, then such an adminstrator may be able to have IPP software listen other ports, such as port 80 and might make it be the only port that the IPP server listens on.  The customer has the right to do what he wants, even if we don't think it is the wisest choice.

I think we need some clarification in the wording here, because I think it's ambiguous as it stands.  Here's another quote:  "IPP server implementations MUST offer IPP services using HTTP over the IANA assigned Well Known Port 631 (the IPP default port). IPP server implementations may support other ports, in addition to this port." > >So you read "suport" and "offer IPP services" to mean "can be configured to listen on" rather than "is required to listen on"? > >    -Carl > >> >> >> "Carl Kugler" <kugler%us.ibm.com@interlock.lexmark.com> on 07/16/98 >> 12:18:26 PM >> >> To:   ipp%pwg.org@interlock.lexmark.com >> cc:    (bcc: Don Wright) >> bcc:  Don Wright >> Subject:  RE: IPP> Re: New IPP Scheme >> >> >> >> >> ... >> > Sorry Larry, but my printer isn't on the default IPP port of 631.  Mine >> is >> > on 80 so my URL is exactly right.  Not all implementations MUST be on >> 631. >> ... >> That's not how I read <a href="ftp://ftp.pwg.org/pub/pwg/ipp/new_PRO/ipp-pro-980630" eudora="autourl">ftp://ftp.pwg.org/pub/pwg/ipp/new_PRO/ipp-pro-980630</a> >> >> It says "It is REQUIRED that a printer implementation support HTTP over the >> IANA assigned Well Known Port 631...".  Therefore, a conforming >> implementation MUST be on 631, although it might also be on some other port >> simultaneously. >> >> ----- >> Original Message: <a href="http://www.findmail.com/list/ipp/?start=4106" eudora="autourl">http://www.findmail.com/list/ipp/?start=4106</a> >> Start a FREE email list at <a href="http://www.findmail.com/" eudora="autourl">http://www.FindMail.com/</a> >> >> >> >> >> >> > > > >----- >Original Message: <a href="http://www.findmail.com/list/ipp/?start=4138" eudora="autourl">http://www.findmail.com/list/ipp/?start=4138</a> >Start a FREE email list at <a href="http://www.findmail.com/" eudora="autourl">http://www.FindMail.com/</a> > </html>
