Businesses involved in manufacturing and packaging can use a handheld inkjet printer to add production and expiry information to products. The 12.7mm printing format allows operators to create visible codes while maintaining a portable workflow. This type of machine can be useful for printing dates on cartons, boxes, pouches, bottles, containers, and other compatible packaging materials. It can also support batch identification and basic product labeling requirements. The handheld design allows coding to be performed at different locations instead of requiring every product to pass through one fixed printer. This makes the equipment suitable for flexible production environments and smaller operations.
