To ascertain this, you will need to find a copy of the MIB
(Management Information Base) file from the vendor in question.
In that file, which if you're lucky will be in human-readable
ASN.1 (Abstract Syntax Notation One), you will find a list of
the OIDs (Object IDs) that the device supports. With those,
you can query the printer directly using the fully-qualified
numeric specification for the OID in question (this is faster
than querying by textual OID).
To find the MIB, I would start with the printer vendor or the
OEM supplier if you happen to know that. Another avenue would be
to use the NET-SNMP tools to "walk" the SNMP OID tree in the printer
and follow the tree as it descends downwards (to the right) after
the "enterprises" branch (i.e. if a walk yields something like
"enterprises.####.$$$$.%%%%" Google first for "enterprises ####",
swapping #### for actual number of course, and continue).
