Labels printing too big for space

I've been printing Poshmark shipping labels via Firefox from my Mac laptop for years. Suddenly, the font size of the label is so enlarged that only a portion of the label prints. If I download the label onto my laptop and then print, it prints in the correct size. I can also print that same label from my old Mac computer and it works correctly. Why is it suddenly not working to print directly from the website (or Gmail)?

Sorry, yes, Firefox 103-104 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 the PDFs in Preview or Acrobat for printing. Here's how to do it on a one-by-one basis:

  • For PDFs that show an https:// address, use the download button on the viewer toolbar to save it.
  • For PDFs that show a file:/// address, click the Downloads button on the toolbar, right-click (Ctrl+click) the item, and open in Preview/Acrobat/System Viewer (the display may vary).

If this is a frequent problem, you can change the way Firefox handles PDFs by default to either ask how you want to open the PDF or just automatically open it in Preview or Acrobat. This support article has the details: https://support.mozilla.org/kb/view-pdf-files-firefox-or-choose-another-viewer
