1643529 - Platform support for toggling of 'Print selection only' in print preview

Status: RESOLVED WORKSFORME

(Core :: Printing: Setup, task, P2)

Description

[Jonathan Watt [:jwatt]]

The way that we currently implement the 'Print selection only' option in the print dialog is to strip the non-selected content out of the document prior to printing. That's fine when the print is done via a dialog where this happens after the user interaction stage, but if we're to support this option in print preview we will also need a way to revert this stripping (since the user will be able to un-check 'Print selection only'. I'm guessing we may need to be able to juggle two documents; an original and a stripped document...

I discovered the new printing dialog today, looks very nice,,,,,, unfortunately
I found that I am unable to use Option: Print Selection Only.

In my mind this is a Major Bug/Problem/Issue. I don't know who would even Print something from a website without using Print Selection Only. It doesn't even make sense to me.

Websites today are so Garbage ridden that simply Printing the entire page is, idk, ill-advised for so many reasons I cannot even comprehend it.

I will try clipping selection to Evernote, but I hate the Invasion of Privacy associated with it, or maybe roll back Firefox until this is fixed or at least we are allowed to configure Firefox to turn off the new feature.

Please let me know if this item is even being considered for short term resolution so that I can plan accordingly.

For the first release this feature will be missing from the new UI unfortunately, but you should still be able to click on "Print using system dialog..." link in the UI to get the system dialog which still has this option. Actually, currently that's broken (see bug 1661975), but that should be fixed soon.

FWIW, rather than switching the pref, note that the new UI can also be disabled in Firefox's preferences/options in the "Nightly Experiments" section (on the left). It's the "Print Preview Redesign" option.

This was essentially fixed by bug 1653340. (See bug 140718 comment 18.)

Bug 140718 will cover the work to expose the functionality in the new printing user interface.
