How to Automatically Trigger PDF Printing in Firefox?

more options

In previous versions of Firefox (up to version 133), it was possible to automatically trigger printing of a PDF file by loading it into an iframe from a sandboxed iframe and call print. However, starting with version 134, this no longer works.

Is there any other way to automatically trigger the print dialog for a PDF file in Firefox, similar to how it can be done in Chrome/Edge (e.g., by opening the PDF in a new window and directly triggering the print dialog without additional button clicks)?

Could you test today's release of Firefox 134.0.2? It fixed some cross-frame logic that might be relevant to your problem, depending on how you trigger printing.
