Abstract
A microcontact printhead device having a frame and an array of at least two printing elements unitarily formed with the frame. Each of the printing elements may include a printing tip, a printing fluid reservoir associated with the printing tip, and one or more flexible support members that attach the printing tip to the frame. Also, a method of fabricating the microcontact printhead device using micromachining and a method of using the microcontact printhead device for printing an array of spots.
