The printing of an image by a thermal ink jet printer is controlled based on an internal temperature of the printer adjacent the printhead and the density of the printed image. Prior to printing, the temperature of the printhead is estimated, and the density of the image is determined from stored print data. Based on the temperature and density, either a single-pass 100% coverage print mode or a double-pass checkerboard print mode is selected. Also based on the temperature and density, the printhead droplet ejection rate is set. Such control provides a printed image with high quality and prevents misfiring of the ink jets when temperatures and density are high.
