I am not sure what value ppmPrinterEnabled adds to the MIB. This appears to be analogous to
On Line/Off Line. If I want to create a driver for the printer I don't care what the current
state is. That information is only necessary when I am ready to print and then this MIB is
I believe that Bert has a valid point in using ppmPortProtocolType. It is not a major effort
to add unknown(2) to the IANA registrations.
Otherwise, the changes are inline with our discussions following the test.

Won't work, because this port is not limited to Internet Suite
protocols. The 'service:' URI in ppmPortServiceNameOrURI may
also be for non-Internet suites (AppleTalk, NetWare, etc.).
I'll correct the DESCRIPTION in the MIB and make clear that
(as with the Printer MIB) ports/channels may be from multiple

Won't work. PrtChannelTypeTC currently only defines 'other(1)'
and (foolishly) does NOT define 'unknown(2)' (unlike every other
textual convention in the Printer MIB). Because the Printer MIB
v2 still doesn't define DEFVAL clauses for most objects, this
oversight has not surfaced before. We could register 'unknown(2)'
with IANA, but _not_ fast enough (because this MIB's going into OS
and printer vendor products right now).

Agreed. My mistake from the old Printer MIB (RFC 1759).
I'll correct the references in the MIB.
