How is the printing industry now? Do you make money by opening a printing house?

I'm a salesman in a printing factory. First of all, if you firmly believe that you must be engaged in the printing industry, you must understand that you said to work in the printing factory first, which is good. I suggest you start at the grass-roots level in the workshop, because only in this way can you learn something real. There are many links in printing, such as typesetting, printing and binding ... If you start your own factory, you can start with one link, such as just typesetting, and then gradually expand the scale. It will be very hard. So as far as business is concerned, it will be very difficult to expand at first. Take books alone, it involves copyright, piracy and other issues, and the small factory that just got up is not easy to recognize. And printing is a manufacturing industry, and there will be a shortage of labor.
