Job Request
A Job Request returns status information about the most recently
processed print job. You can send a job request after an ENQ or
batch.
You can send two levels of Job Requests:
◆
Numeric Error Codes Only (0, 1, or 2)
◆
Verbose (3 or 4)

The job response may not be immediate. If the printer has an
error (out of supplies, ribbon problem, etc.), or has insufficient
memory, correct the problem and then resend the job request. If
the problem is not corrected, no response is returned. If a
formatting error has occurred, the job request will return the
status. The printer must first interpret the format and batch data
before returning the response.
An ENQ can clear errors numbered less than 500. Once the error
is corrected, a job request can be sent. The printer cannot accept
another job request until the error is resolved.
