Asbestos cement board is one of the commonly used materials in the construction industry. It has the advantages of light weight, high strength, fireproof, waterproof, moisture-proof, sound insulation, heat insulation, heat preservation, corrosion resistance, insect bite resistance, impact resistance, easy processing, easy decoration, etc. Good feature, because asbestos cement board has different standard scales, it needs to be marked on its appearance. Hand-held inkjet printers, as a new product, have been recognized by business users since they were put on the market because of their environmental impact and the advantages of instant-on-use. The handheld inkjet printer can modify and transmit data through USB and computer transmission methods. In the outdoor environment, the handheld inkjet printer adopts a touch screen design, which can realize real-time modification and adjustment of the marking content on the spot according to the marking requirements of the asbestos cement board, which not only improves the marking efficiency, but also simplifies the operation process. The working principle of the handheld inkjet printer adopts the inkjet technology of ink supply on demand, no matter how complicated the surrounding environment is, it will not affect the normal use of the handheld inkjet printer. In terms of marking content, the handheld inkjet printer meets all the requirements of the asbestos cement board industry, whether it is graphics, patterns, logos, production date, product batch number, handheld inkjet printers can easily achieve. In terms of labeling cost control, handheld inkjet printers can accurately calculate labeling costs, and companies can perform labeling cost accounting, which provides great convenience. In addition to the application in the asbestos cement board industry, hand-held inkjet printers can also be applied to the surface of various materials such as cartons, wood, plastic, film, metal, and glass.
