Yes, the latest FF (90) release has a problem related to printing and scaling that truncates the page. This has been reported, but no update or time table for a fix has been posted.

Hi All, a patch has been developed for the scaled printing problem and is in testing in the Nightly version (future Firefox 92). Hopefully it will go into beta testing this week (in future Firefox 91). I don't know when it might be released as an interim update for Firefox 90, or whether that will happen.

Meanwhile, printing works normally if the page "fits" when you set Scale to 100%. In some cases, you can use Landscape as a workaround, but I know that will be less useful for many pages.

I did try the 100% scale and all it did was enlarge the part that was able to be printed and only that filled the page, but it did not restore the unprinted section.

I also attempted to save the document as a .pdf, but it saved just like it printed, with the 1/3 missing At the time, the only way to do it was to take a screenshot and adapt the size in photoshop.

I guess I will have to use a different browser until this issue gets resolved.

Thanks

Version 90.0.2 was released today to fix this printing problem. https://www.mozilla.org/firefox/90.0.2/releasenotes/
