Hi Roxana. You haven't shared access to that doc so I can't access it. Can you at least share it with @mozilla.com accounts?

I've not tested Windows yet, but on Mac it seems like the page itself is intercepting the cmd-P key press, resulting in nothing happening. If I focus the location bar instead of the page and then hit cmd-P then printing works, albeit with a popup showing the following warning:

  The page at resource://pdf.js says:
  Warning: The PDF is not fully loaded for printing.

I could not reproduce this.  I tried Nightly on Windows, macOS, and Linux.  On all platforms, when pressing Ctrl+P (or Cmd+P), I get a PDF download of the slide.  Is that the expected behaviour, or should the Google Slides app be intercepting that to show a print preview in the app (like it does when I select "File > Print Settings and Preview" in the app)?

If I focus the address bar and press Ctrl+P, then I can successfully print the view of the Google Slides app.

Hello,

What happens in my case is that it takes a longer time than usual (5-10+ seconds) until the Print pop-up gets displayed, depending on the system (slower on some Windows machines, apparently irrelevant to the performance of the hardware).
Other than this, I can confirm the exact same reproduction as Cameron's in comment 4. I can't reproduce the issue (pop-up not appearing) on neither of the builds (latest Nightly or from the day of the report) or OSes (Mac OS X 10.13.6 or Windows 10 x64).

Jonathan's comment 3 seems to be the closest to reproducing the original issue in the first part of his comment. The second part seems unrelated as a similar error appears if the user does not wait for the content to be loaded completely before attempting to print. 

I could help (if requested) by providing information about the OS or hardware of the machine on which the loading of the pop-up takes a longer time. If there are other ways I can help, please NI me.

Thanks!

On the following specs:

Version 	64.0a1
Build ID 	20181017101626
User Agent 	Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:64.0) Gecko/20100101 Firefox/64.0

I am getting the same issue as Comment 3, but I'm not sure if this is intended behavior.
