Portable Handheld Inkjet Printer, Compact Design — Variable Expiry Date / QR / Bar / Batch Code, 5 Inch Touch Screen

Compact handheld inkjet printer designed for on‑the‑spot coding of expiry dates, QR codes, barcodes and batch numbers. The unit features a 5 Inch LED industrial touch screen with high sensitivity to make operation identification more accurate; the display responds reliably even when used with gloves or wet hands to suit demanding production environments. Cost-efficient printing is achieved through an embedded powerful ink drop consumption algorithm that provides real-time control of ink usage, reducing consumable consumption by 15% compared with similar products. Durable construction uses an ABS + UV industrial spraying body combined with high-end hardware and software components to strengthen anti-interference capability and improve longevity. To prevent nozzle clogging and extend nozzle life, the system adopts the industry "Alternate Printing" model: the left and right rows of ink cartridge nozzles alternate work cycles, avoiding continuous use of a single nozzle row.
