CURRENT_MEETING_REPORT_ Reported by Glenn Trewitt/DEC NPP Minutes Agenda o Walk through LPR/LPD Protocol draft. o Walk through Printer Access Protocol draft. There was a lot to go through on both drafts. Either could have occupied the entire meeting. Because there were very few attendees interested in PAP, compared to LPR/LPD, we dealt only with that in the meeting. PAP was covered outside the meeting (actually, only Jim Jones, the author, and I showed up). This meeting was well-attended, and most of the people had read the draft before the meeting. Early preparation does pay off! LPR/LPD Protocol Draft We finally decided to make a clean break between the existing protocol and this specification, so it would be absolutely clear what was ``in'' the old and new. We paid full attention to old vs. new interoperability issues. Specifically: 1. The ``new'' features were removed from the ``old'' commands: o Zero-length for data files with EOF indicated by connection close. o Data file vs. control file ordering. 2. To provide these (very needed) features, we added two new opcodes: o Receive Data File With Unknown Length - receive a data file, terminated by connection close. o Receive Control File First - receive a control file before its associated data files. For the new commands, we defined explicit rules for how a client should employ them, to achieve interoperability with both old and new LPD daemons. The new draft will have a very solid line between ``old'' and ``new'' LPD features. A new draft will be available in September. 1 Printer Access Protocol Most of the work here was aimed at getting everything in the document that was appropriate for a protocol RFC -- full information so that the protocol is implementable from the document, and removing implementation-specific verbiage. There is still significant work to do on this document.
