Briefly describe how Common UNIX Printing System (CUPS) works.
What will be an ideal response?
Each time CUPS receives a print job, it determines the correct filters, printer drivers, and port monitors to handle device- and channel-specific data and back-ends that send data to the printer (such as USB and serial ports). The print job is then placed in a print queue for printing. Print queues point to printer devices and monitor the printer status and print jobs assigned to them. After a job has finished printing, it's removed from the queue so that the next one can be processed.
