An entry exists in this table for each job in the (logical)
device, no matter what the state of the job is. Each device is
represented as a separate device entry in the Host Resources
MIB device table as a device of type 'printer', 'scanner',
'fax', etc.
The management station references each job using
the xcmJobIdentifierOnSystem assigned by this (logical) device
that accepted the job submission (by some other protocol).
This table augments the Job General Basic
table in this MIB.
