Abstract

PURPOSE:To print different codes on every row at the time of ordinary registration processings, to continue the same printing code when the power service interruption is recovered, and to identify redelivered data, by installing the first and second additional printing code data memories in which additional printing code data of different conditions are set. CONSTITUTION:When operating goods registration, division codes and price data from a keyboard 1 are inputted in a CPU9, and these data are displayed in an indicator 11 by the control of the CPU9 and, at the same time, total price of each division is registered in a division memory 16 of on RAM13 corresponding to the division code after adding. Then, the printing data are edited in one row and stored in a print buffer memory 21, and then, the condition of a symbol flag 18 is discriminated. The additional code data of the first and the second additional printing code data memories 19 and 20 are added to the data in the memory 21 in accordance with the condition of the flag 18, and sent to a printer controlling circuit 15. When ordinary processings are made, different codes are printed for each row, and, when a power service interruption is recovered, the same print code is continuously printed, and thus redelivered data are discriminated.
