    Hi, Sunday (17 July 2005)

    Based on feedback from the Printer Port Monitor Interop event last week,
    below is a brief sketch of a revised PPM MIB with three object groups:

    (1) General - scalars - language tag and counters
        - add ppmGeneralNumberOfPrinters (entry count for ppmPrinterTable)
        - keep ppmGeneralNumberOfPorts (entry count for ppmPortTable)
        - remove ppmGeneralPreferredPortIndex (add to ppmPrinterTable)

    (2) Printer - table - list of printers on system
        - keep Printer-specific elements from previous ppmPortTable
            (for ENA or Network Spooler)
        - maps one-to-one to Printers in Host Resources MIB and Printer MIB
            (via ppmPrinterHrDeviceIndex, if non-zero)
        - rename ppmPortSnmpStatusQueryEnabled to ppmPrinterSnmpQueryEnabled
            (to stay within 31 characters for portability across compilers)

    (3) Port - table - list of logical ports on each printer
        - indexed by ppmPrinterIndex and ppmPortIndex
        - keeps Port-specific elements from previous ppmPortTable

    All tables were reordered to follow Printer MIB and PWG Semantic Model
    conventions - state, name, description, type, other stuff - see below.

    I plan to post clean ASN.1 for this revision by Monday evening.

    Comments?

    Cheers,
    - Ira
