The reliability of an ink jet printer has been found substantially improved, when the pressure in the inks in the printhead nozzles is kept within a pre-determined range of gauge pressures. This range of pressures is between + 0.5 and -10 inches of H20, preferably between 0.0 and -5 inches of H20. In a specific case, this improvement was achieved with a thermal ink jet printer by various means, including:
