A printing apparatus is capable of printing images by ejecting ink droplets from nozzles. The printing apparatus includes: a drive signal generation unit which generates ejectable drive pulses for ejecting ink droplets based on image data indicating the number of ink droplets for each pixel, and outputs the ejectable drive pulses to the nozzles; and a temperature measuring unit which measures the temperature of the ink. The drive signal generation unit also outputs non-ejectable drive pulses to the nozzle when the ink temperature is lower than a predetermined temperature. The non-ejectable drive pulses are generated and output in order that even when the nozzle is driven by the non-ejectable drive pulses, no ink droplet is ejected. It is therefore possible to provide, without substantially increasing the production cost, the printing apparatus which can elevate the ink temperature irrespective of the print coverage when the ink temperature is low.
