When you try printing this page in FireFox (and the same happens with Mozilla
1.7.3) you see a Preparing box and the action stops.

The XP task manager shows FireFox 1.0 eating up 99% CPU.

Need to kill it.

Same page prints with IE.

Same problem on several machines.

Thank you for any help and for your excellent work.

I'm the developer of XWiki.

I've reproduced this problem on my Firefox 1.0. 
To give some pointer, the pages of XWiki make quite a heavy usage of divs and css
I can help detecting the exact part of the page causing the issue by overrding
the templates and removing HTML/CSS one by one..

Attachment: Narrowing of the printing bug

This HTML file containing styles is currently the smallest file I could  do
that reproduces the problem.

Especially, it seems that to following elements are needed to reproduce it:

1/ the big amount of line breaks inside the div section
2/ the image tag in the footer (even without a valid image)
3/ the css directive that are in the head section

I get a similar hang with another div-heavy site.  Trying to print search
results from www.rightmove.co.uk leads to the same problem.

I cant reproduce this bug in 1.0.2. Maybe it is fixed ?

I don't have any printers installed, so I solicited help testing this on IRC. 
Gavin reports this WFM on both branch and trunk.  kbrosnan, by his comments
above, and another person also call this WFM.  Going to mark this resolved WFM.

Maybe a printer/driver-specific problem (I tested on hp LaserJet 1010)? Perhaps
a conflict with other software or extensions? If you narrow down the problem,
please comment here.

I confirm that this problem still happens using Firefox 1.0.2
It is still reported by some users. 
I'm testing using HP PhotoSmart. It was reported using an HP Color LaserJet

Please reopen the bug ! I can't do it !

Please reference comment #7 for an idea of what the problem may be, and some
things that need to be done before this will be re-opened.  Specifically, you
need to make sure there are no driver conflicts, extensions causing the problem,
and do something to attempt to narrow the problem down to something that is
easily reproducible, because several people have tested this, and it doesn't
appear to be a problem.  It also wouldn't be a bad idea to test this on
latest-trunk instead of using the most recent milestone build for your testing.

I also tested with hp psc 1350 on a different computer with Firefox 1.0, no hang.

Please don't be offended, there are a lot of printing bugs, including bugs
causing hangs, some are better reproducible than this. AIUI nobody's is actively
working on printing anyways.

To be sure it's a Firefox bug, please test with
* current trunk build from:
http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-trunk/
* clean profile
* latest printer drivers
Please also indicate whether you and other people test using the site linked or
the provided testcase. Thanks.
