Spooler Components
Figure 12-1. How Spooler Components Interact
1. The application sends its output to the collector process.
2. The collector writes data to the disk and informs the supervisor that it has accepted a job.
3. The supervisor informs the print process where the job can be found on the disk.
4. The print process reads the job from disk and writes the job to the printer.
5. Peruse obtains the job information from the supervisor or lets you examine data on the disk.
6. Spoolcom permits system operators to modify the status of spooler components.
