SUMMARY OF THE INVENTION The present invention aims to solve the problems of the prior art and provides a label printer that changes the printing position of data printed on a label without changing the program.

(Means for Solving the Problems) The label printer of the present invention is configured as follows. That is, the print position and print area size of each of the multiple items to be printed on the label are formed as address data with a leading address attached, and the address data command is stored in memory as an address data table, and the print command is means including a CPU that combines the data stored in the address data table in response to configure label information in a predetermined format and stores it in a print memory; A label printer is configured with a thermal bed drive circuit that prints each item on a label in the same format.

(Function) The present invention develops the position of label 1- of the item to be printed on the label and the size of the print area in a dot pattern in memory, and configures the address data from the first address as an address data table. , the label format desired by the user can be arbitrarily set from the information stored in the address data table.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. The present invention develops the data items to be printed on the label, the position of the label, etc. in the memory of the label printer in a dot pattern, and addresses (
By changing the address data, a label format can be created according to the user's wishes. 1st
The figure is a schematic configuration diagram of a first embodiment of the label printer of the present invention. In the figure, A is a main CPU, B is a thermal head driving CPU, C is a memory in which a format address table is formed, D is a printing memory, E is a thermal head driving circuit, and F is a thermal head.

The thermal printer of the present invention operates as follows.

(2) The main CPU forms address data regarding the label format as shown in FIG. On this occasion,
If a CRT is installed, a label is displayed on the screen of the CRT, and the printing items and their positions are indicated by the starting addresses a, b, and c of each item.

... Input h and set and store the label format developed in a dot pattern in the RAM. That is, an area for each item to be printed is secured in the memory by setting the start address. In addition, if there is no CRT, RO
Fixedly store the label format in M. Main CPU
The data regarding the label format formed is transferred to the thermal drive CPU.

(2) The thermal drive CPU stores the address data transferred from the main CPU in a format address table. FIG. 2 shows an example of a format address table stored in ROM or RAM of memory.

(2) When label printing data is transferred from the main CPU to the thermal head driving CPU, a label format desired by the user is formed on the printing memory (see FIG. 2) according to the thermal head address. This printing memory has a storage capacity of printing information for one label.

(2) Once the data for one label is formed, the data is loaded in order from the print memory and transferred to the thermal head drive circuit.

■The thermal head drive circuit drives the thermal head and prints on the label.

FIG. 4 is a flowchart showing the processing procedure of the first embodiment of the present invention. Next, this flowchart will be explained.

■When it is confirmed that the main CPU is in the processing label format setting mode (step P1), the label format data is transferred to the thermal head driving CPU (step P2).
). If you are not in label format setting mode, check whether a label print command has occurred (
Step P5). The timing at which this label printing command is generated is when the printing switch is turned on in the case of manual printing, and when the printed label is peeled off from the mount in the case of automatic printing. If a label printing command is generated, the label printing command signal is sent to the thermal head driving CP.
Transfer to U (step P4).

TI, processing main CPU for thermal head drive CPU
When data or signals from U are input (step P1+), check whether it is label format data (step P12); if it is label format data, store the data in the format address table (step P+3); issue a label printing command; If so (step P14), the format address table is loaded (step P15). If it is neither label format data nor a label printing command, the process returns to step pH.

Next, step PI is performed to form a label format in the printing memory according to the format address table.
6) Load data in order from the print memory and transfer it to the thermal head drive circuit (step PI7).

Next, the thermal head is driven by the thermal head drive circuit to print on the label (step P18).

FIG. 5 is a block diagram of a second embodiment of the invention.

In this embodiment, the main CPU and thermal head driving CPU of the first embodiment are configured in a single CPUG, and the other components are a format address table as in the first embodiment. A C1 printing memory D, a thermal head circuit E, and a thermal head F are provided.

FIG. 6 is a flowchart showing the processing procedure of the second embodiment of the present invention. Next, this flowchart will be explained.

Start the CPU program and confirm that it is in label format setting mode (Stella 7'S,
), and stores the set label format data in the format address table (step 32). Next, if a label printing command has occurred (step S
3) Load the format address table (step S4), and form a label format in the print memory according to the format address table (step S5). Next, data is sequentially loaded from the print memory and transferred to the thermal head drive circuit (step S6), and the thermal head is driven by the thermal head drive circuit to print on the label (step S?).

The above explanation is an example in which the positions of the items to be printed on the label can be freely set, but it is also possible to select whether to print each item or not.

(Effects of the Invention) As explained below, in the present invention, the printing pattern for one label is developed and stored in the memory RAM as dots, so when printing, the data for that one label is stored. Label printing is easy because all you have to do is read out the information and send it to the thermal printer. Furthermore, since the printing positions of product names, bar codes, etc. are stored as addresses, the printing format can be easily set or changed without modifying the program.
