498787 - Printing Background Colors still prints even when option is unchecked

Status: RESOLVED WORKSFORME

(Core :: Printing: Output, defect)

Description

[Tony Chung [:tchung]]

It seems that unchecking "Print Background Colors" will still print the page with background colors.   Tested at the URL.

Repro:
1) load any 1.9.1nightly or Firefox 3.5 rc1 build
2) go to url, or any site with a background color other than white
3) File > Print, uncheck "Print Background Colors"
4) Click Preview to verify no background colors are shown (its white)
5) Print the page
6) Verify background colors continue to print out.  (blue-gray)

Tested on Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.1) Gecko/20090612 Firefox/3.5

Adding [FFT3.5] in whiteboard.  Came across this issue during RC1 testing

Tony, can you check whether you see the bug on this simple testcase?

Comment 3

[Daniel Holbert [:dholbert]]

Also, if you haven't already, can you double-check that you see this in a fresh profile as well?  (It's feasible that this could be caused by odd/stale configuration in about:config)

FWIW, I can't reproduce this on Linux mozilla-central.  Likely to be Mac-only.

Yep, it was on a fresh profile.

1) Test print with "print background" UN-checked:  
Result: No background color printed.

2) Test print with "print background" checked:  
Result: Light gray background color printed.

Ok, thanks -- that sounds like this testcase shows expected behavior (no bug).  There must be more factors involved, then...

Comment 7

[K Chayka]

I see this in Windows XP, too. Seamonkey 2.1b2pre nightly build 20101130

More factors: In Preferences->Appearance->Colors, set a non-white background color. Mine is an off-white grayish color and printed pages have a background color regardless of the "print background" setting. Change the background color pref to white and the print preview page background once again becomes transparent/white.

tchung, is this your problem, too?

Comment 8

[Cody 'codeman38' Boisclair]

I'm experiencing the issue that's mentioned in Comment 7. I prefer to use a non-white background color by default, and everything prints with that background color rather than the more obvious white.

Firefox 4.0b8, Mac OS X 10.6.5.

Comment 9

[Álvaro González]

I'm having the same problem since I upgraded to Firefox 4 in the two computers I use (Windows XP and Windows Vista). The background colour is the one I've set as default page background in Preferences.

I'm assuming the answer to this is "no", based this in comment 4:
> "Yep, it was on a fresh profile.")
and also this from comment 0:
> go to url, or any site with a background color other than white

(The color set in the preferences should only come into play for sites that don't specify a background color themselves.  tchung's site, http://sportsillustrated.cnn.com/ , *does* set a background color, so he was experiencing something different.)

Resolving this as WORKSFORME, per comment 5 / comment 6.  tchung, please reopen if you can still reproduce.

I'm filing a new bug on Comment 7,8,9. (the issue with a user-specified custom background color)

(And if you can reproduce, it'd be great if you could try to reduce a testcase from http://sportsillustrated.cnn.com/ , since the straightforward reduced testcase (just a page with a background-color) that I created didn't seem to work)
