This handheld inkjet printer provides a practical method of identifying products throughout manufacturing and distribution processes. Its portable design allows operators to print directly onto products, boxes, components, and packaging wherever marking is required. Businesses can use it for serial numbers, batch codes, dates, product names, identification numbers, and other important information. The system reduces the need to transport every item to a dedicated printing station. Fast-drying ink can provide readable markings and support efficient handling. It is applicable in light manufacturing, engineering workshops, warehouses, packaging facilities, construction-material production, agricultural processing, and other industries requiring convenient product identification and traceability.
