we have a web application running and in that web application there is a page that should be printed on paper, after upgrading to version 69 our users have problem with printed page and some of printed elements on printed page or pdf are mixed up, besides there is another confusing point that if i print the same page multiple times i dont get same output each time and some times i get the correct one and some times i get mixed up one ,i have attached two images, including the correct one and mixed up one. any help will be appreciated.

The inconsistency makes it difficult to imagine what is going on.

Is the page fully rendered before Firefox prints? The reason I ask that is there was already a bug reported related to using window.print() in a newly generated document since Firefox 67 -- Firefox was capturing the appearance for printing before all the CSS was applied. But you surely would have noticed that before.

Do you think there could be a problem with how Firefox is handling the font(s) in the document? Do the same characters sometimes get lost or mushed together when you print similar text from a different page -- or only on your web app?

thanks for your answer , the problem was with the fonts, i had some custom fonts and the way i declared them in my css file was not standard enough, although it worked fine before firefox v 69.
