If other troubleshooting steps, such as power-cycling, updated firmware, and checking USB and wireless connections do not fix a printing problem with your Mac computer, the best step is to reset the Apple printing system. Resetting the printing system deletes all queues and jobs, resets all Mac OS printer settings to their default by deleting configuration files, and performas a permissions check on the /tmp directory. This allows you to start fresh. Printers and scanners will need to be added again after resetting the printing system.
