Make a print in winform (no textbox)

Recently, a winform printing function is provided. I don't know much about this because I made it for the first time. So I found a lot of information online. Finally, sort out the source code as follows:

Using system;
Using system. Collections. Generic;
Using system. componentmodel;
Using system. Data;

Using system. text;

Because of the time, many codes do not know the specific meaning. However, this printing function is always implemented. I am posting code here today, hoping that the passing experts will give you some advice on the lack of code. Thank you ~~~
