Marking products is an important part of production. Key information such as production date, shelf life, expiration date, product batch, and trademark name is printed on the product packaging or label through an inkjet printer, which plays a role in product traceability and product identification., product quality and other aspects.

Inkjet printers are used in many industries such as food, beverage, building materials, wire and cable, medicine, chemicals, and electronics. They are generally divided into small character inkjet printers, large character inkjet printers, high-resolution inkjet printers, laser inkjet printers, handheld inkjet printers, thermal transfer inkjet printers, etc. Qiyang proposes a handheld inkjet printer solution based on ARM embedded hardware.

The handheld inkjet printer, also known as a portable inkjet printer, supports portable inkjet printing. Because it is equipped with a large-capacity battery, it can achieve long-term standby without being affected by power supply and venue; it supports the printing of Chinese, English, numbers, symbols, QR codes, barcodes, pictures, variable data, etc., and can be sprayed on the outer packaging of food, beverage and other products, as well as various steel pipes, woven bags, gypsum board, glass and other surfaces. It is especially suitable for coding large items that are not easy to move, so that mobile goods can not be moved. It also has advantages in e-commerce warehouse complement, spray printing of agricultural products, etc.

Working principle of handheld inkjet printer

The general nozzle of handheld smart inkjet printers uses hot bubble inkjet technology, and the nozzle uses semiconductor thin film technology. The nozzle has many high-density spray holes. Thin film resistors are used to heat the ink, and local ink is heated to form bubbles that expand. The ink is sprayed out to form a character pattern. The handheld inkjet printer consists of a touch screen, nozzle, battery, controller, ink cartridge and other parts. The touch screen and high-performance embedded ARM chip form an integrated information input and processing control system for the inkjet printer, which together with the built-in synchronizer encoder form a stable spray printing system.

Handheld inkjet printer hardware solution

The handheld inkjet printer system can adopt Qiyang i.MX8M mini as the core control platform. Compared with traditional platforms with single-chip computers, FPGAs, and DSP as the core, it improves system integration, greatly saves system area, reduces costs, and enhances system stability.

Printer hardware solutions

The i.MX8M mini processor based on the ARM Cortex-A53 quad-core processor is used as the core of the inkjet printer information input system. It is an industrial-grade CPU with a frequency of up to 1.8GHz. It supports running the Linux/Android smart operating system, making the inkjet printing software system operation more stable and smooth; the core board can be configured with 2GB DDR and 8GB eMMC large-capacity memory, which can store a large amount of inkjet character and pattern information for a long time; the processor supports the MIPI display interface and is connected to a high-definition touch screen. Through the inkjet printer's own touch screen, operators can easily adjust the printing content, character size, font, spacing and other contents to achieve good human-computer interaction. i.MX8M mini has rich interface resources, which can lead out multiple USB, RS232 serial ports, etc., connect to the printer print engine, and provide interfaces for external devices of the printer.

Among them, the processor can lead out a USB interface, which serves as the main communication interface of the handheld inkjet printer. It supports the insertion of a USB flash drive, externally imports pictures and printing, leads out an optical interface, connects to the photoelectric sensor, and cooperates with the assembly line to realize assembly line inkjet printing., improve work efficiency, and achieve dual-use handheld online use.

Qiyang industrial-grade high-performance hardware can also be used in automated online printing equipment. The industrial-grade CPU cooperates with FPGA computing and ASIC high-resolution chips to form a printer host system, which controls the actions of external equipment of the printer and processes input signals. Processing, processing character data required for printing, achieving high-speed graphics processing, high-definition decoding, high-speed flash memory and efficient code coding.
