How does a print job move through the spooler once it is submitted with the lp command?
- Print requests are submitted with the "lp" command.
- The lp command communicates with the scheduler (lpsched, also known as the spooler daemon).
- lpsched obtains the configuration information for the printer, creates the necessary files for the print job, and queues the print job.
- The print job waits in the proper print queue behind any other jobs until the other jobs are finished.
- When it moves to the front of the print queue, the print job is filtered by the interface program for the printer queue and sent to the printer.
