A handheld inkjet printer can provide convenient on-demand printing of barcodes and QR codes for product identification, tracking, inventory management, and packaging. Operators can print codes directly onto suitable cartons, packages, components, or products, helping businesses label items without relying exclusively on pre-printed stickers. The portable design makes it practical for warehouses, production floors, dispatch departments, and small manufacturing facilities. In addition to codes, users may print product names, serial numbers, batch information, and dates where supported. Clear, consistent printing can assist scanning and identification processes. It is a useful option for businesses seeking flexible coding and traceability solutions.
