Abstract: A printhead, particularly a light emitting diode (LED) printhead, which has improved apparatus for distributing signals to individual printing elements, i.e. LEDs, that are used in the printhead. Specifically, this printhead contains a number of print element arrays, typically arrays of light emitting diodes, and a corresponding number of drive circuits all of which are mounted to a common member, this member illustratively being a metallic stiffener plate. Each of the drive circuits is connected to a corresponding one of the print element arrays. All the print element arrays are typically situated in a co-linear orientation transversely along the member with the drive circuits co-linearly arranged along a side of the arrays.
