PURPOSE:To uniformize the use frequency between dot printing parts such as wire pins by providing a counting processing part counting the respective operations of a plurality of dot printing parts constituting a printing head one at a time and integrating the number of times of the respective operations to apply the integrated data. CONSTITUTION:When the one dot row data of a line buffer are latched tree times by one dot by a dot row data latch 4, a printer control CPU 1 supplies printing data to 24 pin corresponding impact counters 7 of a printing head impact number-of-time measuring part 6 while divides the same into three bites. At this time, each pin corresponding impact number-of-time counter 7 renews its own count value by +1 when printing data are printing execution data. By this method, the printing head impact number-of-time measuring port 6 executes the above mentioned processing from one dot row immediately before a printing head 5 starts printing to one dot row immediately before the finish of printing. |
