Abstract

PROBLEM TO BE SOLVED: To heighten the printing speed by drastically cutting back the transfer time which has been prolonged due to inputting a large amount of data at the time of the initial load or the data renewal so as to accelerate the transaction processing and improve the service. SOLUTION: At an external part 1, image data such as a stamp logo are compressed with any compressing means and transferred to a printer 2 with an image data transfer command. The image data transferred and received by the printer 2 are stored in a memory means 3. When the image data transfer command is recognized by a memory data administrating means 4 and the data are compressed, a thawing command is sent to a compressed data administrating means 5. The compressed data administrating means 5 recognizes the defrosting command so that the image data compressed and stored in the memory means 3 are defrosted and restored in the memory means 3 so as to serve as the image data to be printed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a printer, and more particularly to a printer to which a large amount of data such as image data is inputted from outside. More specifically, for example, P
As represented by a printer of an electronic register used as a terminal device of an OS (Point of Sale) system,
The present invention relates to a printer that prints a stamp logo such as a store name, a store name, and a mark.

[0002]

2. Description of the Related Art In a conventional printer of this type, a control method for increasing a printing speed has been proposed in Japanese Patent Application Laid-Open No. 63-172662. FIG. 3 is a principle block diagram.
The image data is stored in the storage means 35 by the initial load, and the storage data management means 36 recognizes the print command of the image data included in the input print information, and stores the image data in the storage means 35 based on the print command. And print it on the printing paper. In this way, when printing a stamp logo in the electronic register, if the stamp logo printing data is initially loaded into the storage means of the electronic register, the stamp logo printing data is transferred from the outside to the electronic register every time the stamp logo is printed. No longer needed
Printing speed can be increased.

[0003]

The above-mentioned conventional printer has a problem that it takes a long time to transfer a large amount of data such as image data to the printer.

[0004] It is an object of the present invention to provide a printer in which a large amount of data, such as image data, is transferred to a printer, thereby reducing the data transfer time.

[0005]

The printer of the present invention decompresses compressed data input from the outside, restores it as print data, and stores it.

A printer according to the present invention includes a storage unit for storing data input from the outside, a storage data management unit for issuing a decompression instruction when the input data is compressed, and a storage unit for storing the data. And a compressed data management means for recognizing the instruction to decompress the compressed data and decompressing the compressed data stored in the storage means and storing it again in the storage means.

In the printer according to the present invention, the stamp logo print data may be compressed and inputted at the time of initial loading or data update, and the inputted stamp logo print data may be decompressed and stored in the storage means. .

[0008]

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. Referring to FIG. 1, an external device 1 mainly indicates a higher-level device, and is generally a POS (point-of-sale information) system main unit or a higher-level host computer.

The printer 2 includes a storage unit 3, a storage data management unit 4, and a compressed data management unit 5.

The storage means 3 stores data input from the external device 1 to the printer 2.

The storage data management means 4 recognizes a data transfer command, a print command, and a normal processing command. In the case of a transfer command of image data or the like and the data is compressed, the storage data management means 4 instructs the compressed data management means 5 to decompress.

The compressed data management means 5 recognizes the decompression instruction from the storage data management means 4, decompresses the compressed image data and the like stored in the storage means 3, restores it to the storage means 3, and prints again. Image data that can be used.

Next, the operation will be described.

FIG. 2 is a flowchart showing the operation.
The external device 1 compresses image data such as a stamp logo by some compression means at the time of initial loading or data update (step 11), and transfers the image data to the printer 2 with an image data transfer command added thereto (step 12).

The image data transferred and received by the printer 2 is stored in the storage means 3 (step 13).

The storage data management means 4 recognizes the image data transfer command (step 14), and if the data is compressed, instructs the compressed data management means 5 to decompress (step 15).

The compressed data management means 5 recognizes the decompression instruction, decompresses the compressed image data stored in the storage means 3 and restores it again in the storage means 3 to obtain image data to be printed (step 16).

If it is determined in step 14 that the command is not an image data transfer command but a print command, normal printing is performed (step 17).

According to this method, the data transfer time from the external device 1 to the printer 2 can be greatly reduced, and the printing speed can be increased.

[0021]

As described above, according to the present invention, when a large amount of data such as image data is transferred from an external device to a printer, the data is compressed and transferred and decompressed by the printer. The transfer time required for inputting a large amount of data at the time of updating the data can be greatly reduced, and the printing speed can be increased, the transaction processing can be speeded up, and the service can be improved.
