Harry,


I brought up this subject with Larry Masinter (who is the IETF HTTP Chair)
when I met him last week. He claims that the HTTP does not really care about
the port number and that hence it would be no point in using a different
number fore the printing protocol. Can somebody else, who is supplying Web
servers, verify this?
