A printing system includes an information processing apparatus, an image forming apparatus, and a printer driver storage device. The variable resistance memory device includes a semiconductor substrate and a string selection switch formed on the semiconductor substrate. Gate width and gate length of the transistor and gate width and gate length of the transistor are adjusted so that source-drain current flowing between the source and the drain of the transistor becomes equal to source-drain current flowing between the source and the drain of the transistor when the voltage applied to the input terminal is set to be preset trigger voltage. A plunger extends at least partially into the fluid chamber from the proximal end. , the feed forward filter and feedback filter, so that each filter spans the maximum anticipated length of the CIR.
