Abstract
A method of one embodiment of the invention is disclosed that determines the temperature and/or firing resistance of a thermal fluid-ejection nozzle as the fluid-ejection nozzle is fired. The method determines whether the fluid-ejection nozzle ejected fluid upon firing based on the temperature and/or firing resistance of the fluid-ejection nozzle.
