Multi-function DataGrid print class (WinForm C #)

The print function as shown above can be implemented.

· All fonts, margins, Header are high, high travel, can be customized.

· Supports automatic calculation of the number of rows per page and fixed lines per page.

· Support footage display page number.

Because you use it with your own, you are set to be public, be careful when you value.
