In TAC,you can go back the logs for any particular job and see the data that was printed to stdout/console for any run of the job. That is visible when you
highlight a job in Job Conductor
select the "logs" tab
select a particular run from the list in the "logs" tab
click on the "download it" button labelled "Job execution log:" in the information tab
I usually find the Execution Logs folder in the TAC server. Access it on /data/talend631/executionLogs, there you can see which tasks that are listed per folder.
