ABSTRACT:
A process and apparatus for generating and displaying the number of printed sheets of paper and the print ratio occupied by black pixels on the print paper in a page printing apparatus. The apparatus stores print data corresponding to one page in a page memory upon initiation of a print mode, calculates a print ratio of black pixels with respect to an overall area of a print paper, updates the number of printed sheets of paper and the print ratio of black pixels thereto, and accumulatively stores the updated number of printed sheets of paper and the print ratio in a statistic memory. A current time is checked upon initiation of a timer interrupt mode, the daily-average number of printed sheets of paper and the daily-average print ratio are updated on the basis of the current number of printed sheets of paper and the current print ratio stored in the statistic memory at the end of each day, and the updated daily-average number of printed sheets of paper and the updated daily-average print ratio of black pixels are stored in the statistic memory. The monthly-average number of printed sheets of paper and the monthly-average print ratio are updated on the basis of the daily-average number of printed sheets of paper and the daily print ratio stored in the statistic memory at the end of each month, and the monthly-average number of printed sheets of paper and the monthly-average print ratio, the daily-average number of printed sheets of paper and the daily-average print ratio, and the current number of printed sheets of paper and the current print ratio stored in the statistic memory may be displayed upon selection of an output mode by a user.
