Does web page printing always need to clean the browser cache in order to be normal?

A small system written by PHP in the intranet, which has a printing function. The print page is opened in a new window, and the style is always lost in the occasional print preview. It is normal in the browser window, that is, the loss of styles occurs during print preview. CSS style rules have been made for printing, and this happens several times a day.
at this time, after emptying the browser cache, you can print normally again.
how to solve this problem?
