The 12.7mm handheld inkjet printer is designed for businesses that need to add batch and serial identification to their products. Its portable design allows operators to code individual items, boxes, or packages conveniently. Fast-dry ink supports efficient production by reducing the possibility of fresh markings being smeared during handling. Applications include manufacturing, packaging, electronics, hardware, food processing, logistics, and warehousing. The machine can be used for batch codes, serial numbers, production dates, expiry dates, product references, and other traceability information.
