An entry exists in this table for each document in each job, 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', 'scanner', o 'fax', etc. 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).
