4.2 Language Monitor

Language Monitor is a part of the Printer Driver and the Windows Spool System. The main roll of the Language

Monitor is that sends a job start message to the Status Monitor. Therefore the Status Monitor

can start polling to get the printer status.

The second roll is that sends the job information such as User ID and Job ID to the Status Monitor and the Printer

F/W. Hence the Status Monitor can stop polling because the Printer F/W informs the Status Monitor that printing

job is complete.

4.3 Status Monitor

Status Monitor has no user interface. It shows only HTML help when any error occurs during printing jobs.

Status Monitor Data Flow

After polling is started, Status Monitor has to know when it stops the polling. For this reason, the Network

Printer Server should inform of completing job when the printing job is finished.

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.
