Abstract
An ink-jet printhead is designed with different sets of firing chamber configurations on the same printhead. One set of firing chambers provides for relatively large-volume drops and rapid refill times to facilitate draft-mode printing. A second set of firing chambers provides smaller drop volumes and more controlled refill rates that are optimized for high-quality printing.
