Today, I don’t know what’s going on. Our company’s uv printer can’t use it anymore. So I called professional maintenance personnel. After they saw it, they started to repair it. After a while, they finished it. Now we can use it more quickly. Usually everyone’s work is very tense, so there are many. Documents are also very time-consuming, now since the uv printer, we have also reduced a lot of trouble, can print out the desired effect faster, so that they can save a lot of time to do their own work, every day is happy, to enjoy their better life. The present society.
