An entry exists in this table for each job in the device,
no matter what the state of the job is. Each printer is
represented as a separate device entry in the Host Resources
MIB device table as a device of type 'printer'.
The management station references each job using
the xcmJobIdentifierOnSystem assigned by this (logical
for spooling or physical for non-spooling) device that
accepted the job submission (by some other protocol).
The management station accesses each document in the job using
the xcmDocSequenceNumber from the xcmDocGenBasicTable.
This table extends (for print jobs only) the
Document General Basic table in this MIB.
