JobImpressionsCompleted is an integer valued printing attribute
class that specifies the number of impressions completed for the job so far.
For printing devices, the impressions completed includes interpreting,
marking, and stacking the output.
JobImpressionsCompleted attribute describes the progress of the
job. This attribute is intended to be a counter. That is, the
JobImpressionsCompleted value for a job that has not started
processing must be 0. When the job's
JobImpressionsCompleted value is intended to increase as the job is
processed; it indicates the amount of the job that has been processed at the
time the Print Job's attribute set is queried or at the time a print job
event is reported. When the job enters the
ABORTED states, the
JobImpressionsCompleted value is the final value for the job.
IPP Compatibility: The integer value gives the IPP integer value. The
category name returned by
getName() gives the IPP attribute name.
