A versatile handheld inkjet printer can be used for coding and identification across a wide range of compatible surfaces. With suitable ink, businesses may mark cardboard, paper, plastic, metal, glass, wood, leather, and other materials. Its portable construction allows the operator to bring the printer directly to the product instead of moving products to a fixed machine. It can print dates, numbers, text, batch information, symbols, barcodes, QR codes, and other supported content. This makes it valuable for manufacturing, packaging, warehousing, logistics, workshops, and retail businesses. The ability to work across different materials makes one portable printer suitable for multiple product categories.
