The process is simple:
First, set the start and end print tags in asp.net page. To ensure that the tags are not displayed during web browsing, we use" < ! -- HTML notes > ". Such as: < !--startprint-- > and < !--endprint-- > .
Then write the relevant JavaScript code, see the code below.
If you do not want the print button to be printed, note that the print button is included in the < !--startprint-- > and < !--endprint-- > Outside.

Observe the code above you can see, print, window. document. body. innerHTML assignment was to be a need to print the web part of the code (this is prnhtml), and then by recursively call setChildNodesByCurrentNode (artibody size) change the style of the related child nodes, all change the font size and style in order to achieve the purpose.
