For the Job Monitoring MIB: two objects are used to represent
a full 62-bit value. The sign bit of each half is not used.
This object is generalized for use with input devices as well.
ISO DPA: Octets-completed [high 31 bits]
This attribute indicates the number of octets of the job that
the printer(s) [devices(s)] have completed printing
[processing]. The server shall not
reset its value during the processing of multiple copies of
documents or the job. Since this attribute is intended to
measure the progress of a job, the value shall include repeated
pages due to multiple copies.
The accuracy of this value is implementation-dependent. It may
be approximated by the number of octets conveyed to the
printer [device]. This attribute may not be supported for all
printers and all page description languages.
The value of this attribute shall be 0 if the device has not
started this job.
