Abstract: According to an example, a method for TIJ printing may include applying, by a processor, F electrical firing pulses to a resistor of a TIJ printhead for a duration of about 0.50 to 1.00 μs to jet a latex ink or a dispersed polymer particle ink from a nozzle. According to another example, a TIJ printing apparatus may include a TIJ printhead including a firing chamber to jet a latex ink or a dispersed polymer particle ink from a nozzle, and a resistor to heat the latex ink or the dispersed polymer particle ink to jet from the nozzle. The TIJ printing apparatus may further include a memory storing machine readable instructions to apply F electrical firing pulses to the resistor for a duration of about 0.50 to 1.00 μs to jet the latex ink or the dispersed polymer particle ink, and a processor to implement the machine readable instructions.
