Bluetooth printer picture processing and storing system

Abstract

The invention discloses a Bluetooth printer picture processing and storing system, and relates to a printer internal file processing and storing system. The method comprises the following steps: performing format scanning and classification on picture files; rejecting the pictures which cannot be identified by the printer from being stored; compressing the picture file; writing the picture addressoffset and the initial address of the storage database file into a memory according to the attribute of the picture file; calling the currently processed and stored picture into the corresponding storage area, wherein the storage address of the currently processed and stored picture is the sum of the initial address of the storage database file and the address offset of the picture file; and storing the corresponding file into the corresponding storage space. Files transmitted to a printer can be automatically managed and compressed, the occupied memory space can be reduced, and the receivingand sending speed of photo files is reduced; and the memory space position can be saved, the storage and file transceiving accuracy is improved, the file transceiving speed is increased, and the fileprocessing efficiency is improved.

Description

technical field [0001] The invention relates to a file processing and storage system inside a printer, in particular to a picture processing and storage system of a bluetooth printer.

Problems solved by technology

This type of portable bluetooth printer is welcomed by the majority of users. With the upgrading of electronic products, the clarity and pixels of various photos are getting higher and higher, and the file space occupied by a single photo file is also increasing. For the bluetooth printer itself The photo storage and photo file management requirements are getting higher and higher, and the file processing system that comes with the printer itself is difficult to meet people's file needs.

[0004] Under operations such as long-term storage and deletion of a large number of large-capacity photo files, it is easy to cause a large workload of image file processing
