Referencing Unix and LPR/LPD in the Channels Group discussions

I would like to make a couple of comments regarding some of text in
the just-posted minutes of the PMP project meeting in San Diego.


In the "Channels Group" section of the minutes:


  "For UNIX TCP/IP it would be a port number.  For other protocols it
   might be something else."


I believe the phrase "LPD/LPR" should replace "UNIX TCP/IP" here.


Unfortunately, too many people seem to believe that LPR/LPD is a
Unix-only thing.  While it is true that LPR/LPD was developed in
the Unix environment, it has since grown to become widely supported
in non-Unix environments, including DOS/Windows, Macintosh, VAX/VMS
and other environments.


It also seems that some people tend to refer to LPR/LPD as simply
"TCP/IP" when discussing this topic.  We must be careful to not
propagate this incorrect reference, as many other printing protocols
utilize TCP/IP, including HP's port 9100 technique, IEEE TIPSI, and
many others.


Let's try to consistently use the phrase "LPR/LPD" (or simply "LPD")
when talking about this protocol environment during the subsequent
discussion of the Channels Group.  (If someone has a better term
than "LPR/LPD" or just "LPD", that's great, so long as the term
distinctly describes the LPR/LPD protocol environment.)
