PROC PRINTTO will write the the log file, as long as the PROC PRINTTO itself executes.
Is it possible there was an error in your code before the PROC PRINTTO step? That could make SAS enter syntaxcheck mode and may not execute the PROC PRINTTO step. It might be easier to start by avoiding PROC PRINTTO, and focus on the log files created automatically. Most schedulers will basically batch submit the SAS jobs, and there will be a logfile written somewhere that the administrators have set up. If you don't know where your log files are being written, you may want to ask your admins or other colleagues.
Also note, depending on how you have set the logic in your flow, if Job #1 errors, Job #2 may never start. The scheduler should allow you to determine whether execution of Job #2 is dependent on successful execution of Job #1 or not.
