When Status Monitor requests a job status, the Printer Server returns the job table that contains user id, job id, and job status (printing or complete or canceled). 4.5 Printer Driver Status Monitor The Printer Driver and the Status Monitor can set/get some data to the system registry to share the Status Monitor information such as the polling interval. When the user wants to set the option of the Status Monitor manually, he or she can set it using the Printer Driver User Interface. So, if the user set option that the Status Monitor is disabled, the Status Monitor can's show HTML Help to the user although the error has occurred while printing.
