The 12.7mm portable inkjet printer is suitable for industrial environments where products require clear and identifiable date coding. Its handheld design makes it convenient for small production lines, workshops, warehouses, and mobile marking tasks. Fast-dry ink helps markings dry rapidly after application, minimizing unwanted smearing. It can be used to print manufacturing dates, expiry dates, batch numbers, serial numbers, and other information on cartons, plastic, metal, glass, wood, and suitable coated surfaces. The portable design provides flexibility without requiring a permanent installation.
