My apologies to Tom Silver for delay in forwarding this request.

Below is a request for new IANA Printer MIB registrations from

[Tom's reply on 27 September]

Hi Ira,

Thank you very much for the quick response!

FYI, the maximum capacity for ink stick depends upon the channel hardware
capacity of the machine. Some Xerox machines support a maximum of 4 ink
sticks per color channel and some machines support a maximum of 6 ink stick
per color channel as shown within the previously enclosed screen shot. I
supposed the ‘hundredthsOfInkSticks(20)’ could be made more generic to
something like ‘hundredthsOfItems(20)’ instead. Just a thought…

BTW, I had a feeling that the toner type request may be met w/ some
skepticism. No worries though, just something that needs to be considered…

Hi Michael,

I am interested in your thoughts on these two enum proposals when you get a

Thank you for taking the time to consider these proposals…

Hi Tom,

Mike Sweet (Apple, IPP WG Secretary) and I are the current IETF
Designated Experts for IPP Registry and Printer/Finisher MIBs.

Mike - would you please read and think about these enum requests.

Tom - the process is that we put new IANA Printer MIB enum requests
on the WIMS WG list for review for at least two weeks - then we consider
(as a WG) the comments, if any.  Then we (as a WG) decide to accept
the requests (hopefully) and Mike or I send them to Amanda at IANA.


My immediate thoughts are:

(1) What is the MaxCapacity for ink sticks (a bunch of ink sticks)?

(2) I see your point about standard versus matte toner, but I'm very
nervous about these synonyms for 'toner' as a marker supplies
type - e.g., nobody will use 'standardToner' for quite awhile and,
when they do, Apple and Microsoft and tools like HP WJA will have
to fold them back together - hmm...

- Ira
