My system is to print the record number of, but the record is the number of click on the print button, preview also calculate, if you want to record the real print the number of times, it is difficult to achieve 2 is meaningless, printer paper, ribbon is bad print is not clear, and so on the reason how to calculate? Print half power? Integrated these factors, can't get real results, so, just click on the word
