    Hi,

    The actual order of a few of the fields will be slightly different.
    I was tired when I wrote that note below. But content the same.

    I'll send out some new diagrams soon too, but for each use model:

    (1) Network Spooler
        - 1 ppmPrinterTable entry for each downstream network printer
        - 1 ppmPortTable entry for each supported protocol type

    (2) External Network Adapter
        - 1 ppmPrinterTable entry for each downstream hardware interface
        - 1 ppmPortTable entry for each supported protocol type

    (3) Network Printer (or Internal Network Adapter [INA])
        - EXACTLY ONE ppmPrinterTable entry (and one hrDeviceIndex)
        - 1 ppmPortTable entry for each supported protocol type

    Cheers,
    - Ira

    > 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.
