Well, what I’m interested in is the part of the error_log that contains the messages of the test print.
Try to get the job number (job ID) of the test job and then execute
grep 'Job xxxx‘ error_log > job_log
where error_log is your 200K huge file and job_log the name of the excerpt file.
Post that as a text file.
