A print command is received and a short, single, electrical precursor pulse is generated to preheat the ink components near the surface of the heating element. The precursor pulse returns precipitated ink components near the resistor to solution. For best results, the precursor pulse occurs approximately 1.50 microseconds prior to the main drive pulse even though other times, such as 1.00 microsecond, can produce adequate results. The main drive pulse then occurs to print the required information.
