Yes, there are many printing houses in every university. Don't underestimate these small print shops, the surface is dirty and the inside is messy. They earn more money in a day than a college student can imagine. For a person who comes to print something, what he sees is to plug the USB flash drive into the computer, open what he wants to print, and then print. Yes, everyone can print simply, but you may not know the specific operation. For example, if you need to print 8 sheets of paper on both sides, what should you do? You won't. You can only ask the owner of the printing shop for help. But if you work in a printing shop, the boss will give you some specific printing methods to use when the printing shop is busy. These methods will benefit you for life.
