There is also provided a method for printing information at a given power supply capacity level, comprising the steps of: examining the a group of rows of dots to be printed; calculating the maximum dot utilization value for the group; selecting a print speed based on the maximum dot utilization value; printing the first row of the group of rows; and repeating above steps until the information is printed.
