Description

DETAILED DESCRIPTION OF THE INVENTION [Outline] A printer for repeatedly printing image data such as logo printing, comprising a storage means for storing initially loaded image data and an image data included in input print information. A printing speed can be increased by providing storage data management means for recognizing a print command and outputting the image data of the storage means, and printing the image data output by the storage data management means on a print medium.

[Industrial application field]

The present invention is, for example, a point of sale information management (Point Of Sales:
The present invention relates to a printer of a transaction processing device in a system or the like, and more particularly to a printer capable of increasing printing speed.

In recent years, with the spread of computer network systems, in department stores, supermarkets, specialty stores, etc.
POS systems have become widely adopted. Electronic registers are used as terminals of this system. The electronic register is operated by an operator such as a store clerk, the product presented by the customer is registered, and a receipt is issued by the printer. In addition to the transaction data, the receipt is printed with image data, which is usually called logo printing, such as store name, store name, and mark.

Therefore, the same image data is repeatedly printed every time a transaction is made, and a method of increasing the printing speed is desired.

[Conventional technology]

In FIG. 4, the electronic register 1 is composed of a display 2, a printer unit 3, a keyboard unit 4, a cash drawer 5, and a control unit 6, and a receipt issuing port 7 is provided at the center of the upper surface of the printer unit 3. There is.

Therefore, in the electronic register 1, when the operator inputs transaction data from the keyboard unit 4, the control unit 6
In addition to being stored in the transaction data memory, the product number, product name, unit price, and operation instruction to the operator are finally displayed on the display 2, and finally the necessary calculation processing is performed by the operation of the input end button to make the total amount. Etc. will be displayed and the payment will be settled.

With the progress of the input of transaction data, the printer unit 3 sequentially prints on the receipt 70 and the journal by dot printing, the total amount is printed, and the receipt 70 is issued from the receipt issuing port 7.

As shown in FIG. 5, the receipt 70 is printed with image data such as a store name, a store name, or a mark, that is, a logo print L. The logo print data is sent from the control unit 6 to the printer unit 3 for each transaction and printed on the receipt 70.

The logo print L may be printed on the upper area or the lower area of the receipt 70, and FIG. 5 shows the case of printing on the lower area.

When printed in the upper area, immediately after the transaction receipt 70 is cut, it is already printed when the transaction data is printed on the top of the receipt 70 of the next transaction,
When printed in the lower area, it is printed after the transaction data is printed.

[Problems to be solved by the invention]

According to the above conventional method, the transaction data and the logo print data are transmitted from the control unit of the electronic register and printed on the receipt every time the transaction is performed, and the logo print data is sent in the bitmap format, which requires a lot of transmission time and printing. It takes time. Therefore, when printing on the upper area of the receipt,
You cannot register the next transaction while printing the logo. If printed in the lower area, the receipt of the receipt will be delayed due to the logo printing after printing the transaction data. Therefore, there is a problem in that not only the transaction processing time is long, but also the customer is made to wait, resulting in deterioration of processing efficiency and service.

[Means for solving problems]

 FIG. 1 shows a block diagram of the principle of the present invention.

In the figure, reference numeral 35 is a storage means for storing image data in a bitmap format for a plurality of print characters to be loaded at a predetermined time, and 36 is a storage means 35 for recognizing a print command of image data included in input print information. Is a storage data management means for outputting the image data of.

Therefore, the image data output by the storage data management means 36 is configured to be printed on the print medium.

[Action]

Image data in bitmap format for a plurality of print characters is stored in the storage means 35 by initial loading, and the storage data management means 36 recognizes the print command of the image data included in the input print information and recognizes it. Based on storage means 35
By printing the image data of the above and printing it on the print medium, the image data can be printed without transferring each time, so it is possible to increase the printing speed, improve the efficiency of transaction processing, and improve the service. You can

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 2 and 3. The same reference numerals denote the same objects throughout the drawings.
In FIG. 2, the ones corresponding to those in FIG. 1 are shown surrounded by a one-dot chain line.

In FIG. 2, the control unit 6a of the electronic register 1a includes an initial load data memory 60 for storing logo print data, a logo command unit 61 for instructing logo print, and a transaction data memory 62.
It is equipped with an initial load data memory when the power is turned on at the start of work.
The logo print data stored in 60 is initially loaded into the printer unit 3a, and the logo command unit 61 has a function of instructing the logo print at a timing when the logo print is required. Others are the electronic registers described in the conventional example. It has the same function as the control unit 6 of No. 1.

In the printer unit 3a, the logo print data memory 35a is
The storage means stores the initially loaded logo print data.

The logo command recognition unit 36a recognizes the logo printing command sent from the logo command unit 61 and recognizes the logo printing data control unit 36b.
It has a function to send a command to.

The logo print data control unit 36b uses the logo print data memory 35 based on the command sent from the logo command recognition unit 36a.
It has a function to read the corresponding logo print data from a.

Further, 30 is a main control unit, 31 is an interface circuit, 32 is a space control unit, 33 is a line feed control unit, 34 is a print control unit, 3b is a print head, and M ₁ and M ₂ are motors.

With this configuration and function, the case of logo printing in the lower area of the receipt will be described with reference to the flow chart of FIG. 3. First, the logo print data is initially loaded in the logo print data memory 35a at the start of work.

When print information is input to the interface circuit 31 by registering transaction data, space data, line feed data,
And print data are respectively the space control unit 32, the line feed control unit 33,
Then, the print head 3b prints the receipt paper sent to the print control unit 34.

After printing the transaction data, logo command section 61a
Sends a logo print command to the interface circuit 31, and the logo command recognition unit 36a recognizes the logo print command.

Then, the corresponding logo print data is read from the logo print data memory 35a by the logo print data control unit 36b and sent to the space control unit 32, the line feed control unit 33, and the print control unit 34, respectively, to print the receipt paper. Printing is performed and a receipt 70 is issued.

In this way, by transmitting the logo print command from the control unit 6a, the logo print data memory 35a of the printer unit 3a outputs and prints, so that the transmission speed does not take time, and therefore the print speed is increased. It is possible to improve the efficiency of transaction processing and improve services.

The above example explained the case of the receipt printing of the electronic register used in the POS system, but it can be generally applied to the printer in which the graphic printing of the same logo is repeatedly printed, and the same effect can be obtained. To be

As described above, according to the present invention, the graphic data such as the logo print data is initially loaded and stored in the storage unit of the printer unit so that the data when the print request is made can be stored. Since the transfer time is greatly reduced, the printing speed is increased, and the transaction processing efficiency and service can be improved.
