<P>PROBLEM TO BE SOLVED: To provide a highly efficient thermal inkjet print head and a printer system using such a thermal inkjet print head and a method of ejecting a liquid droplet using the print head. Ž<P>SOLUTION: The thermal inkjet print head is provided with a plurality of nozzles 3 and one or more heater elements 10 corresponding to each nozzle. Each heater element 10 is configured to heat a bubble forming liquid in the print head to a temperature above its boiling point to form gas bubbles 12 therein. The generation of the gas bubbles 12 causes the ejection of a liquid droplet 16 of an ejectable liquid (such as ink) through the respective corresponding nozzle 3. Each heater element 10 is formed of solid material, more than 90% of which, by atomic proportion, is constituted by at least one element, from the periodic table of elements, having an atomic number below 50.
