(Below is the response I gave you in our private conversation.)
I don't know the answers. The definitions for finDeviceMaxCapacity and finDeviceCurrentCapacity in RFC 3806 aren't clear at all on what a maximum capacity or current capacity means in the context of a finisher. Ira, can you provide any clarifications on these?
It also seems a bit too wide open to let the printer choose the unit type.
Your example also raises an interesting question about stackers. The Finishing MIB defines 'stacker' as a finisher type. But IPP "finishings-col" doesn't have a representation for stackers - it considers a stacker to be an "output-tray".
Mike, what do you think we ought to do about the FinDeviceTypeTC types in the Finishing MIB that don't have IPP equivalents in finishings-col?
