ABSTRACT:
A thermal print head with a plurality of spaced-apart electrical conductors carried by a support with a surface area provided at an end portion of each conductor. A common electrical conductor is provided having a thin portion for each surface area which is spaced from and essentially parallel to the surface area with resistive material disposed between the common electrical conductor and each of the surface areas. The print head provides a path for current flow and thermal flow through the resistive material in a direction essentially perpendicular to the surface areas.
