Printing images and text at wrong size

I'm using the latest version of Firefox on Mac OS X 10.14.6.

Whenever I go to print PDFs from Firefox, usually through Gmail, if there are any images in the PDFs they are blown up way past their margins and rendered unreadable. This isn't a huge issue but it is affecting some text as well, meaning I can't print the documents directly from Firefox. I can download the documents and print them from Preview just fine, so it isn't an issue with the printer.

I'm attaching a screenshot of my print settings and an example of what Firefox is outputting (converted to JPEG so I can upload it).

Sorry, yes, Firefox 103 for Mac has a bug with PDFs that contain embedded images or which consist of one huge image. The image is not scaled correctly, so this happens:

  • Embedded images: the image is enlarged within its original boundaries and much of it gets lost
  • Entire PDF is an image: the image flows off the page regardless of what kind of scaling you try

There is a bug on file for this, and hopefully there will be a fix in Firefox 105. For now, I'm not aware of any workaround to make it work in Firefox. You can open PDFs in Preview or Acrobat for printing. If you want to change the way Firefox handles PDFs by default because this is a frequent problem, here's a link to the support article: https://support.mozilla.org/kb/view-pdf-files-firefox-or-choose-another-viewer

Thanks for letting me know about this. Knowing that it's an ongoing bug I'm happy to just save and open PDFs in Preview.
