Description

[Detailed description of the invention] Technical field of invention The present invention relates to a label printer.

Technical Background of the Invention and Problems Therein Generally, in a label printer, as shown in FIG.

), barcode (5), etc. are printed on it and issued. For such printing, each item is individually set with a PLU code as a call number, and by inputting the PLU code, the item name data, unit price data, etc. corresponding to that item are recalled from the PLU memory area and printed. It is something. Here, the standard number of PLUs is 350, but 1

line). Therefore, the PLU memory area requires 96 bytes x 350 = 33,600 bytes.

In particular, in the past, rP as shown in Figure 1(a)
It used to be enough to print one or two lines of product name information, such as OUND CAKEJ, but these days, this is no longer sufficient for special products, and as shown in Figure 1 (b), rPOUN

OBJECT OF THE INVENTION The present invention has been made in view of the above points, and it is an object of the present invention to provide a label printer that can meet requests for printing auxiliary product names such as materials in addition to normal product name printing while saving memory. With the goal.

SUMMARY OF THE INVENTION The present invention relates to product name information, which is divided into normal product name data and auxiliary product name data such as materials, stored separately in a main memory area and an auxiliary memory area, and a combination of the two is used to print data on a label. By creating and printing the information, the amount of auxiliary product name data such as materials is generally required to be reduced, so the necessary printing can be performed while greatly reducing the overall memory requirement.

Embodiment of the Invention An embodiment of the present invention will be described with reference to FIGS. 1, 3, and 4. Basically, for product name information as shown in Figure 1(b), there is a main memory area for normal product name data such as "rPOUND CAKE", and r5UGE.
It is divided into an auxiliary metric area for auxiliary product name data such as ``R, FLOUR, ...''. Here, the main memory area has three PLUs as before.
50 pieces are required, and the configuration of the IPLU memory is the third one.
As shown in the figure. That is, the IPLU memory consists of 98 bytes, and the p1 main memory area is 98 bytes x 35
0=consists of 34,300 bytes. Here, the difference from the conventional example shown in Fig. 2 is that a 2-byte print table chain is added (therefore, 98
(It is a part-time job). This print table chain is a part that stores data for specifying the name of the auxiliary product, and the data in buildings 1 to 100 specifies the print table Nα in the auxiliary memory area shown in Figure 4. is not specified if is 00. On the other hand, in the auxiliary memory area shown in FIG. 4, one memory consists of 144 bytes (36 characters x 4 lines), which is 100 characters. The tC1 auxiliary memory area consists of 144 bytes x 100 = 14,400 bytes. The reason why the number of memories in the auxiliary memory area can be reduced to 100 for the number of PLUs of 350 is that unlike the case of normal product names, the content of auxiliary product names such as materials and additives remains the same even if the product changes. This is because there are things that can be shared, things that are unnecessary from the beginning, etc., and the number is about 100.

Therefore, looking at the total memory, the main memory area is 34,300 bytes and the auxiliary memory area is 14,400 bytes, resulting in a memory capacity of 48,700 bytes.
Compared to the conventional 84,000-pi)K, the memory capacity is approximately 60% smaller.

Incidentally, the printing operation is performed using any combination of the main memory area and the auxiliary memory area.

When a PLU code is input, first, the main memory area in which the PLU code, product name data, unit price data, etc. are stored is searched for the designated PLU code. Therefore, if there is a corresponding PLU, data for that IPLU (98 bytes) is transferred to a predetermined working area (not shown). Next, check the contents of the print table chain. If the data is 0, the PLU call is terminated, but
If the data is between 1 and 100, it is transferred from the auxiliary memory area where the auxiliary product name data is stored to a predetermined working area (not shown) containing 144 bytes of the auxiliary product name data corresponding to the print table, and then PLU of
Terminate the call. After calling the PLU, the item is placed on a scale, its weight is measured, and the price is calculated based on calculations with the unit price.Print data is created accordingly, and labels are printed and issued. In other words, if the content of the print table chain is 0, it will be printed as shown in Figure 1 (a), and if it is between 1 and 100, it will be printed as shown in Figure 1 (b).
You can perform any necessary printing such as . For example, in the case of regular meat at a butcher's shop, only 2 lines of #:l: are printed for the product name, and for processed meats such as ham and sausages, 6 lines of product name information including the ingredients are printed. can do.

In addition, in this example, the target of the auxiliary product name was explained using the materials of the product, additives, etc.
It also includes information such as.

Effects of the Invention As described above, the present invention stores normal product name data and auxiliary product name data such as materials in the main memory area and auxiliary memory area, respectively, and combines them to create print data. As a result, necessary printing can be performed while greatly reducing the memory capacity as a whole.

Claims (1)

[Claims] In a label printer that weighs an item and prints the item's name, unit price, weight, price, date, code number, etc. on the label, a PLU code is set as an individual call number for each item, and a PLU code is assigned to each item. In addition to normal product name data, we have a main memory area that stores data for specifying auxiliary product names along with unit price data, etc., and an auxiliary memory area that stores auxiliary product name data such as product materials and additives. A label printer characterized in that print data on a sillage is created by any combination of a main memory area and an auxiliary memory area.
