Firefox printing

[steven at bsd-q1.nospam.homeip.net]

With FreeBSD 8.2R and Firefox 3.6.13:

When printing postscript to file (or PDF, and actual printers too), the
font and spacing of text is incorrect and does not look good.
When I do the same on Firefox 3.6.13 on Ubuntu 10.04, I get clear output.

 have included test-bad.ps to illustrate the difference,
n the archive test-ps.tgz.  I also converted test-bad.ps to jpg for quick
view.  Test-good.ps is about 150k larger, and too big to include on this list.  
I have included  the jpg version test-good.jpg.
(The example is just a printout of blank CUPS jobs, in which CUPS has
 nothing to do with problem)

I took a look at https://bugzilla.mozilla.org/show_bug.cgi?id=490475
which may or may not be related to this problem,
but I still don't understand why the same firefox build delivers different
results (unless ubuntu added patches?).

Thanks for any leads,

Steven
