The universal printer manufacturers are mainly distributed in the Pearl River Delta region. Dongguan, Guangzhou and Shenzhen have many homes and large scales. There are not many R&D and production capacity. When purchasing a universal printer, in addition to selecting a good quality, suitable model, we must also choose a manufacturer with a good service awareness and professional after-sales service technical team. Although the universal printer is a high-tech digital device, it has no professional operation and maintenance, and its service life will decrease. In order to ensure that the machine has a problem, we can get timely after-sales service in the first time, be sure to inquire, and evaluate the strength and reputation of the manufacturer through multiple channels!
