A queue manages the print jobs that shall be passed to a printing system.
Transfer is based on FIFO principal (First In - First Out); however, the order of the print jobs can also be altered manually. Using queues, management of print jobs and efficiency of printing systems can be controlled optimally.
In addition for many printing systems queues can help to automate processes, e.g. grouping of jobs according to specific criteria etc.
Every queue controls one printing system. To rip and print on several printers at the same time, it is necessary to have the required number of queues.
