If 'On' PostScript received over this channel is
processed as pure binary data.
If 'Off' PostScript is interpretted as ASCII or TBCP data.
The value 'other' shall mean not specified.
Devices should NOT implement this object, should instead
implement the equivalent object xcmPrtChannelBinaryPostScript.
This xcmPrtChannelBinaryPostScriptZ object appears for
backward compatibility support only, since some few devices
implemented the object at this OID. Clients/managers wishing
to support those devices should try to access both objects
(which generally can be done with a single SNMP message packet
combining requests for both object OIDs) and use whichever
object is present in the device.
