PURPOSE:To avoid duplicated output of a print data by comparing year/month/ day/hour data stored in a nonvolatile memory with a data received newly and outputting a print data only when the new data is large. CONSTITUTION:In receiving a command data through an interface circuit, a CPU 5 discriminates whether or not it is a command of year/month/day/hour/ minute/second and when the data is the command, the year/month/day/hour/ minute/second data of a coupon outputted from a RAM 7 at last is read. Then the quantity of the readout data and the data inputted this time is compared and when the data inputted this time is larger than the data /read from the RAM 7, the data inputted this time is stored in a prescribed address of the RAM 7 and outputted as the print data for the print in a coupon print area. |
