> Drive-by: do I understand correctly that this corresponds to the _actual printer_'s unprintable area? If so, is this not a major fingerprinting vector? Or is this somehow not able to be exfiltrated? If I understand correctly, this env variable would only be usefully exposed *at the time that the user chooses to print* (and selects a printer in their print UI, and the browser lays out the document using the selected page size etc. for that printer). It wouldn't just generally be exposed (or it would be exposed as `0`) for web pages viewed in a browser window. So: it does technically add some fingerprinting surface, but only for content that *is printed* (and I think there's already quite a bit of fingerprintable surface that's exposed at that point). -- GitHub Notification of comment by dholbert Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/11395#issuecomment-3001539818 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
