Printer load balancing is a feature used when several print jobs are sent to a group of printers. Load balancing will distribute the print jobs to other printers in a round robin fashion. Printer pooling does not work this way. Instead it sends print jobs to a primary printer in a non-round robin fashion. If the primary printer is busy, it will then route to secondary printers. When the primary printer becomes available again, print jobs will resume on the primary print device.
