User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_1) AppleWebKit/534.48.3 (KHTML, like Gecko) Version/5.1 Safari/534.48.3 Steps to reproduce: Using Mac OS X 10.7.1, and Firefox 8.0.1 or Nightly 11.0a1 (2011-12-08): opened a page which contained an iFrame whose window.onload contained a function telling that iFrame to print. Example: http://jsfiddle.net/WZh3V/ Actual results: Print dialog box appears, however clicking "print" results in no action; clicking "PDF > Save As PDF…" produces a zero-byte PDF file. Expected results: Print dialog box should appear and clicking "Print" should result in document being sent to the print spooler. Click "PDF > Save as PDF…" should save the PDF, not produce a zero-byte file. Correct behavior is seen on Mac OS X 10.5 and Mac OS X 10.6. Correct behavior is seen under Mac OS X 10.7 using Safari or Chrome.

Also, using Firefox 8.0.1, clicking the "Print" link in the demo results in a modal dialog box "Printer Not Available". Same thing happens when right clicking and choosing "This Frame > Print frame". *This* behavior is not reproducible in Nightly, only in 8.0.1. Attaching screenshot of this issue.

This is Firefox 8.0.1 -- This *works* in Nightly

It would be good for tracking, but otherwise 8 is 2 versions ago and won't get any patches.

I am able to reproduce the bug in version in 9.0.1 if that's what you're asking Paul...
