Hi Mike,

I like this "printer-finisher" proposal for exposing the Finisher MIB info.

A few comments:

(1) TYPO - Section 6.15.3 in title and second example says
"printer-input-tray"

(2) TECHNICAL - Section 16.5 should also reference finDeviceAttributeTable
and later sections should reference a (flattened) "finisher-detail" member
that
is a simple key/value mapping for all defined finisher-specific attributes,
e.g.,

- general: deviceModel, finReferenceEdge, numberOfPositions, etc.
- subunit types: stitching (staple,stitch,saddle,dual), folding, binding,
etc.
- subunit details for stitching and punching

WDYT?

Cheers,
- Ira
