High resolution inkjet printer system based on embedded linux

Abstract

The invention relates to a high-resolution inkjet printer system based on embedded Linux. The high-resolution inkjet printer system comprises an upper computer unit and a lower computer unit, whereinthe upper computer unit takes an ARM processor as a core, carries the embedded Linux operating system, and comprises an upper computer spray printing control module, a data editing module, a parametersetting module, a system tool module and a state display module; and the lower computer unit takes an FPGA as a core, and comprises an SPI control module, a data processing module, an SDRAM control module, a lower computer spray printing control module and an exception processing module. According to the high-resolution inkjet printer system based on the embedded Linux, the information of texts,patterns, variable two-dimensional barcodes, variable counters and the like is printed, the printing speed of variable data is improved by adopting the method of updating the variable data by a fixedaddress, and the printing quality and recognition rate of QR codes are improved through the QR code generation algorithm.

Description

technical field [0001] The invention relates to a high-resolution inkjet printer system based on embedded Linux. Background technique [0002] With the development of society, people have higher quality requirements for consumer goods in daily life, and pay more and more attention to the production date, expiration date and other information of products. information. At the same time, in order to realize product traceability, prevent products from being counterfeited, improve warehouse management efficiency, use two-dimensional barcodes for precise marketing, and increase product popularity, companies also need to identify their products. The application of the inkjet marking industry is becoming more and more extensive, and the market demand for inkjet printers is increasing day by day. [0003] Therefore, with the development of barcode technology and the popularization of mobile terminal identification systems, anti-counterfeiting, traceability, and marketing systems ba...

Problems solved by technology

In recent years, the demand for domestic inkjet coding equipment has been increasing, and a number of inkjet printer manufacturers have emerged, but most of these manufacturers have imitated foreign products or jointly developed them with foreign companies. Most of the domestic self-developed inkjet printers are controlled by single-chip computers. , there are shortcomings such as low printing efficiency, complex structure and single function, which cannot meet the increasingly high quality requirements of modern enterprises
