Printing logging information from a scheduled function screws up the current display of (running jobs).
Also, the display of the tick marks doesn't work on all platforms.

Isn't it better to simply print two lines (instead of the tick marked layout):
"Scheduled [job name]"
"Finished [job name] with status [...]"

Any logging info would come between those lines.
