Indicates what printer sub-systems are currently
processing this print job. The last OID field for this
dynamic object contains the job ID.
cSourceSubsystem - some of the job is in the printer
I/O subsystem.
cProcessingSubsystem - some of the job is in the
printer imaging processing subsystem.
cDestinationSubsystem - some of the job is being
printed.
Additional information:
For LaserJet 4500 cSourceSubsystem and
cProcessingSubsystem will always be set and cleared together.
They are set when the beginning of the job is detected and they
are cleared when the end of the job is parsed.
A non-printing job will never set cDestinationSubsystem.
When a page is ready to be printed (the intermediate has
been built and the page is closed by the personality),
cDestinationSubsystem will be set even if a page of a
previous job is currently being printed.
cDestinationSubsystem remains set until the last page
of the job has reached an output bin.
If a page requires extensive processing and allows all the
previous pages of a job to complete printing,
cDestinationSubsystem will remain set
until the last page of the job has finished printing.
There will be between 0 and 16 instances of this object in the printer at any given time since the
printer keeps track of up to 16 jobs.
