After going through the white paper again, it occurred to me that the current printer-xxx-temperature-current and printer-fan-speed-current attributes are reporting a subset of what we would normally get from 2D printer subunits. For example, the printer-input-tray attribute provides all of the Printer MIB's prtInputTray properties encoded in a string instead of a single roll-up status value.
What do people think of extending those attributes a bit, e.g.:
printer-chamber (1setOf octetString)
Values are strings like 'status=N;temperature=N'. Status is a bitfield providing detailed status and temperature is the current temperature in degrees Celsius.
printer-chamber-description (1setOf text)
Values are strings like 'Acme heated chamber'.
*If* these values ever got exposed via SNMP (not sure that would be useful), then we'd be able to map things cleanly from these attributes to SNMP properties.
