The local press and publication administration has the obligation to guide the legal training of the printing industry. Of course, they may not care about specific training matters. Generally speaking, however, there may be some local training institutions responsible for similar legal affairs.
The relevant certificate of printing industry qualification is issued by the vocational and technical department, which mainly depends on whether the employees of the printing unit have the qualification, and it is personal.
For example, driving requires a driver's license. This license is a driver's license. The certificate of the training course of printing laws and regulations is issued by the administrative department of printing, usually the Press and Publication Bureau, the General Administration of Press, Publication, Culture, Radio, Film and Television or the Comprehensive Law Enforcement Bureau of Culture, which mainly proves that the enterprise has participated in the training of laws and regulations in the region, knows the law, and can abide by the law.
Simply put, some laws and regulations in the printing industry are relatively simple. As far as our conventional understanding is concerned, as long as illegal printed matter is not involved, the labor law is implemented normally and various taxes and fees are paid, this law and regulations are basically unnecessary. Law-abiding business will not touch these laws and regulations at all. Anyway, it's just an invisible shackle you can't see.
