A simple typing and copying shop only needs one printer and one copier. If the printer can be used as name labels, cards and recipes in an advertising store, you can buy a photo machine, or you can go to your peers for processing and painting. Of course, you can also deal with it directly with your peers. Now the price of painting is relatively low. If you don't have a lot of business, you don't need to buy machine business cards and leaflets. These things can be processed directly in the printing factory and delivered to your door at a good price. Of course, we need two computers or one computer and invite another person.
