S/W Structure and Descriptions 4 4. S/W Structure and Descriptions 4.1 Architecture The belt CRUM interface board is a transmission belt CRUM interface board of the photoelectric Dry Color Laser Printer, mounted on the printer body, making it possible to physically combine the body and the belt CRUM board. Printer Driver Language Monitor Status Monitor Printer F/W Network Card F/W 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. Service Manual Samsung Electronics 4-1 S/W Structure and Descriptions 4.4 Network Interface User ID + Job ID + Printer Data Printer Driver Printer Data Language Monitor Printer Server (Kernel / NPC) Printer Name Port Name User ID Job ID Printer Server IP Addr SNMP Request Printer Status Printer Status Printer Server (Kernel / NPC) Job ID Status Monitor Request Job Status Job Table 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.
