Printing the contents of a pdf
.js iframe fails
This is not to be confused with https://bugzilla.mozilla.org/show_bug.cgi?id=792816 which is about permissions on the PDF file. Not about security within the browser. To reproduce, try http://storage.michaelaquilina.com/ff-print/ (click on "Print the PDF") and notice the "[13:34:55.653] Error: Permission denied to access property 'print' @ http://storage.michaelaquilina.com/ff-print/:10" console message. This means that the second example on https://developer.mozilla.org/en-US/docs/Printing is broken if the URL you load in the iframe is a PDF file. This used to work on Firefox 12 (the oldest I had available) but isn't working in 21, 23 or 24. (haven't tested Beta). It also works in Chrome.

I tried with FF8, clicking on "Print the PDF" doesn't do anything.
This works fine for me with Adobe Reader on Windows 7 w/FF21, but not pdf.js When loading with Adobe Reader, the iframe loads a PluginDocument which creates an Adobe Reader object. PluginDocument has a hook for forwarding print calls to the plugin, so Reader's print function is called. pdf.js appears to load as a chrome document, which the content page cannot reach into. It either needs to provide a similar print hook or run its top-level document as content.

Open the Web Console and you'll see the permission error.
Priority: -- → P3
Summary: Printing the contents of an iframe that loads a PDF is no longer possible → Printing the contents of a pdf.js iframe fails
Relevant comment from https://github.com/mozilla/pdf.js/issues/5397#issuecomment-100372486: > I think I know the reason for this, at least in Firefox. In a simple example such as the above, > if you use the Firefox DevTools to examine document.domain in both the main page and in the > iframe, I found that document.domain is pdf.js for the PDF.js renderer—so the browser's cross-origin > restrictions are kicking in. Similarly, I don't think this is directly a PDF.js bug, though I've no idea if there is a good fix. > Additionally, if I built PDF.js from source, and set my iframe to web/viewer.html?file=, then calling > telling the iframe to print (as in the OP), it worked fine.
