/etc/qconfig spooler configuration file
The /etc/qconfig file describes all of the queues defined to the base operating system.
A queue is a named, ordered list of requests for a specific device. A device is something (either hardware or software) than can handle those requests one at a time. The queue provides serial access to the device. Each queue must be serviced by at least one device; often it can be handled by more than one device.
