摘要： The printing operation of an ink jet printer is controlled based on the density of the image to be printed. Using the density, a required drying time for each swath of printed matter is determined based on the image density. Also using the density, a maximum print frequency of firing the ink jets is determined. The density is determined by filtering stored print data by dividing the print data into blocks and determining a maximum number of ON pixels in a block. Such filtering enables clusters of ON pixels to be detected thus providing a more accurate determination of the density.
