Abstract
A fluid ejecting device with a body defining an array of nozzles. The nozzles are arranged in an array along an array axis. The array has a first portion in which the nozzles are spaced apart along the array axis by a first pitch, and a second portion in which the nozzles are spaced apart by a different second pitch. The array may have a third portion between the first and second portions with a third pitch different from the first and second pitch. An assembly may include two or more of such fluid ejection devices, and the second portion of one print head may be aligned with the first portion of the other print head. Printers incorporating the fluid ejection devices and printing methods are also disclosed.
