We discovered that many printers can't distinguish between NICs in terms of
ifIndex. AT least one printer can. Should we try to characterize this?

For instance, for the majority of the implementations, does this imply that
services are the same on both NICs? Or, does this imply that, when you walk
the Channel table, you only "see" services appropriate for the NIC "through
which" you are accessing the printer at that time?

I can see how the "one NIC table" could be a practical approach if you think
in terms of "there's a printer... tell me what I can do with it... at THIS
IP address". But, if there were not 100% overlap in services per NIC, and
a query through one NIC shows all the services but all seem indexed to "NIC
1", I can see trouble.

I wasn't sure, by some of the comments, whether or not we have this situation.
