A unique value for each job set in this MIB. The jmJobTable and jmAttributeTable tables have this same index as their primary index. The value(s) of the jmGeneralJobSetIndex SHALL be persistent across power cycles, so that clients that have retained jmGeneralJobSetIndex values will access the same job sets upon subsequent power-up. An implementation that has only one job set, such as a printer with a single queue, SHALL hard code this object with the value 1. See Section 2 entitled 'Terminology and Job Model' for the definition of a job set. Corresponds to the first index in jmJobTable and jmAttributeTable.
