Beschreibung
Zusammenfassung:	A thermal ink jet printhead including a substrate (411), a resistor layer (415) on the substrate having ink drop firing resistors (111,211,311) and energy controlling resistors (214,314) defined therein, a metallization layer (417) adjacent the resistor layer and having metallic interconnections formed therein for providing serial energy controlling connections between predetermined ones of the ink drop firing resistors and predetermined ones of the energy controlling resistors, a plurality of ink containing chambers (423) respectively formed over the metallization layer (417) adjacent respective ones of the ink drop firing resistors (416), and an orifice plate (429) secured over the chambers and containing a plurality of nozzles (431) respectively associated with the chambers.
