A printer 5 having a line thermal head for printing sales information such as product name 9, unit price 10 and total on null paper,
It is connected to a keyboard 15 for a store clerk to instruct and input total calculation and the like.

As shown in FIG. 1, the memory unit 3 has a PRI.
CE LOOK UP memory area (hereinafter referred to as PLU memory area) 6 and print buffer area 7,
The PLU memory area 6 stores, for each product code 8, a product name 9, a unit price 10, and a type code 11 representing the type of each product such as fresh fish and vegetables. In the print buffer area 7, the type buffer 14 is divided for each type code 11, and the same number as the type code 11, for example, "1" for vegetables, is provided for each type buffer 14. It is attached. Then, by reading the product code 8, PL
Product name 9 and unit price 10 retrieved from U memory area 6
However, each type of buffer 14 is divided by type code 11
Stored in.

The central processing unit 2 fetches the commodity code 8 read from the scanner 4, refers to the PLU memory area 6, writes information to the print buffer area 7, and issues a print command.

Next, the printing of sales information on the receipt 12 will be described with reference to FIGS. 1, 2 and 3 according to the flowchart of FIG. FIG. 4 is a flow chart showing the printing procedure of one embodiment.
It is a chart. When the clerk reads the bar code attached to the product with the scanner 4 in step S1, the central processing unit 2 refers to the PLU memory area 6 in step S2 and corresponds to the read product code 8. The product name 9, unit price 10, and type code 11 to be searched are searched. At this time, for example, when the product name 9 is "tomato" and the unit price 10 is "100 yen" and the type code 11 is "1", the central processing unit 2 determines that the type code 11 is "1" in step S3. Since the type code 11 inside the print buffer area 7 is "1", the product name 9 "tomato" and the unit price 10
"100 yen" is stored.

In step S4, the central processing unit 2 proceeds to step S5 if the reading of the scanner 4 is completed and the clerk presses the total key (not shown) of the key board 15, and if not, proceeds to step S5. Returning to step S1, the operations from step S1 to step S3 are repeated until there are no more products to read.

In step S5, the central processing unit 2 calculates change when the amount of deposit from the customer is input from a key (not shown) by the clerk, informs the clerk of the amount of change, and deposits from the clerk. The input of the amount of money becomes a print command, and in response to this print command, the central processing unit 2 receives the product type in the type buffer 14 storing the product name 9, the product name 9 stored in the type buffer 14, and the unit price. 10 is output to the printer 5 in order to collectively print 10 and 10 in the order of the determined type buffer 14. Then, the printer 5 prints the product type, the sales information, the subtotal of each product type, the deposit amount and the change amount on the receipt 12 shown in FIG. 3 and the journal paper not shown by the line thermal head. To do. By using a line thermal head in which the heating elements are arranged so as to intersect the paper feeding direction, printing speed can be increased, so printing is completed while the clerk takes out the change from the cash tray, and the customer is informed. The receipt 12 is handed over with the goods and the change.

The printed receipt 12 is printed for each product type regardless of the order in which it is read by the scanner 4, so at a glance it can be seen what and how much was bought for each product type.
