Problem in automatic job scheduling Report

Dear Expert,

I want to run a report Using the job scheduler to print a report automatically at either shutdown or at a particular time. I setup the job scheduler and ran the scheduler by clicking on Administration->IT Administration-> Job scheduler-> Job Scheduler Overview->Functions->RUN NOW and the report started to print. The result was successful and I picked up the printed report from the printer.

Now the problem is when I schedule it to print automatically at a specific time and when that time is up nothing happened. It does not print. Can anyone help me with this problem. I want the report to run and print at either shutting down of the computer or at specified time.

Any idea please.
