PURPOSE:To easily decide whether the data transmitted to a printer is correct or not by adding the marks to unauthorized codes in the received data and printing these codes in the order of reception. CONSTITUTION:The data sent to a printer are analyzed after reception and the normal codes are identified from the unauthorized codes. In case of the received data dump, the received data undergoes the hexadecimal number conversion. Then an underline is added to the converted data as a mark in case of the unauthorized codes. The printed data is edited in a data editing process and the data are successively received until the data equivalent to one line are edited. Then the data are printed at the time point when the data equivalent to one line are edited. Thus it is possible to know the unauthorized codes by checking only the data on the mark added to the print result of the received data dump. In such a way, the correctness of the received data can be easily decided. |
