As shown in FIG. 2, the two-color printing unit 4 has a receipt 29 handed to a customer, a journal 28 for recording and storing sales, and a take-up spool 25 for winding the journal 28.
And the thermal head 21 for printing the receipt 29
And the thermal head 22 for printing the journal 28
And a thermistor 30 and a thermistor 31 for measuring the temperatures of the thermal head 21 and the thermal head 22, respectively.
The applied energy table 27 is supplied with the print data and the print color designation data from the control unit 2, and the temperature information of the thermal head 21 and the thermal head 22 is supplied from the thermistor 30 and the thermistor 31. 27, a printer control unit 26 that determines the applied pulse width to the thermal head 21 and the thermal head 22 and controls the printing of the printer.

As the journal 28 and the receipt 29, a two-color color thermosensitive recording paper used for two-color printing of black and red is used. This two-color thermosensitive recording paper has different thermal energies required for color development between black color development and red color development.
When printing with 2, the thermal energy required according to the print color designation data from the controller 2 and the temperatures of the thermal head 21 and the thermal head 22 is selected from the applied energy table 27 and printing is performed.

FIG. 3 is a data storage diagram of the applied energy table 27. The applied energy table 27 shows, as shown in FIG. 3, the temperature of the thermal head and the corresponding time to energize the thermal head in the case of red printing and the time to energize the thermal head in the case of black printing. The black pulse width shown is stored.

Next, the operation of the POS terminal device of this embodiment will be described.

When the sales product identifier (usually reading a bar code by a bar code reader) and the quantity are input from the input unit 1, the control unit 2 reads the product name and unit price input from the storage unit 3 and reads the quantity as the unit price. Multiply by and calculate the price, display these on the display unit 5, and instruct the two-color printing unit 4 of these print data and print color designation data (in this case, normal data, black print designation). .

When the printer controller 26 is supplied with the print data and the black print designation data from the controller 2, the black pulse width corresponding to the temperature information supplied from the thermistor 30 and the thermistor 31 is applied to the applied energy table 27.
