Portable handheld inkjet printer can help logistics and shipping teams add identification information directly to packages and containers. Users can print shipment references, product codes, batch numbers, handling information, serial numbers, and other supported markings. The handheld format makes it convenient for warehouses and dispatch areas where packages vary in size and shape. Instead of relying entirely on pre-printed packaging, operators can add variable information when needed. The printer is useful for e-commerce fulfillment, distribution centers, courier operations, manufacturers, wholesalers, and retailers. Its portability supports flexible package marking throughout receiving, storage, picking, packing, and dispatch processes.
