The below VB script can be used to restart print spooler service at regular intervals with Windows task scheduler.

'======================================
'This script serves as a workaround to poorly written printer drivers
'                   
'It checks the spooler folder to see if there are any active jobs.
'If it is empty it will restart the spooler service.
'It works best as a regularly scheduled task.
