Hi As we recently updated Mozila Firefox, we discoverd a new issue with the software. Whenever we tried to print out a PDF, it came out blank. We went to your trouble shooting guide to solve this problem: https://support.mozilla.org/sv/kb/fix-printing-problems-firefox. But after removing the printer from Firefox, we discovered that even the preview of the page we're trying to print is now blank, and therefore won't even print a blank page. We can assure you that the printer is not the problem, as it works perfectly fine any other time. I've attached an image below of how the preview looks like for us.
