Abstract

Printhead 10 (Fig. 1) comprises a metal plate 12 having a line A of printdots 14 extending along plate 12 adjacent its top edge. Alternate ones of printdots 14 are connected by inner layer conductive lands 16 (Figs. 2 and 3) with contact or connector pads 18, and the other alternate printdots 14 are connected by means of outer layer conductive lands 20 with contact pads 22. The lands 16 and 20 have a half-width offset, and the same is true of the contact pads 18 and 22, staggering lands 16 and 20 and staggering pads 18 and 22, so that sufficient electric current conducting and contact areas are provided for dots 14 even though the printdot spacings are very close along line A.
