Have a look at this: Another DataGridView Printer[^]

It''s recent, seems to work, and you can contact the author directly by using the "New Message" at the bottom of the page if you have problems.

通过代码查找您已发布，PrintDGV似乎为空.或Print_DataGridView方法内的内容为空.

Going by the code you have posted, PrintDGV seems to be null. Or something inside Print_DataGridView method is null.
