The Bugbug bot thinks this bug should belong to the 'Core::Graphics' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Are you certain that Acrobat Reader DC runs in the browser or does it open as a separate application; I am not sure this is actually a Firefox issue?

The document displayed and printed incorrectly in a separate tab in Firefox with no involvement from Acrobat Reader DC using
"file:///c:/Users/Gary/Desktop/Sample-BERN_PCT522-1.pdf"

Acrobat Reader DC ran as a separate application and displayed and printed the document correctly. (I don't even known how to run Acrobat Reader "in the browser".)

Oh I am sorry, I misread your first comment. You are saying that Acrobat Reader DC printed correctly, whereas Firefox shows a white background around the SAMPLE text, it makes sense to me now.

[BugBot [:suhaib / :marco/ :calixte]]

The bug has a release status flag that shows some version of Firefox is affected, thus it will be considered confirmed.

Moving this from Core Graphics to Firefox PDF viewer component. I've reset the severity to ensure it is triaged again since the meaning of severity might differ between components.

I can repro this on Windows 11 with Firefox 107, so I assume it's independent of Windows version and I did mozregression which found it was broken at least as far back as Firefox 95.

The console shows a lot of warnings:

Warning: getPathGenerator - ignoring character: "Error: Requesting object that isn't resolved yet Helvetica_path_D.". pdf.js:456:13

The rendering is correct in setting the pref pdfjs.disableFontFace to true.
