You can get also faulty results with printing as follows:
Go to http://www.largeformatphotography.info/qtluong/sequoias.big.jpeg by example.
click on the picture, so that the pictures isn't sized to the size of your screen.
Now choose print preview and choose scale Stretch to fit.
The image isnt stretched to the page.

Is this still happening with a current nightly build from
http://ftp.mozilla.org/pub/mozilla.org/firebird/nightly/latest-trunk and a fresh
profile?

Attachment: Results from test image

Luke Nowak - 25 February 2004

Using the latest trunk of Firefox 0.8+ for Windows XP Pro, I was able to obtain
these results. The two pages printed are not the same as was displayed under
print preview. In print preview Firefox showed two pages with the first page
cutting off the bottom of the image and the second page showing the bottom of
the image that was cut off. The first page of the results has the image scaled
in height to fit the full height. The second page has a squashed portion of the
image in the correct area of the page.

Conformation of bug with alternate steps of replication.

Successfully able to replicate the bug on Windows XP Professional, with
"Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv: 1.6) Gecko/20040206
Firefox/0.8"

Steps for replication:

Step1. Open a browser window and open the following URL
http://www.largeformatphotography.info/qtluong/sequoias.big.jpeg

Step2. Go to “File” menu and select the “Print Preview” menu item. This will
display the image preview.

Step3. Without clicking on the image, change the “Scale” size to 100% and click
“Print”.

Step4. Close the print preview window and reopen it using the step2.

Step5. Now select the “Scale” size to be 100% again and simply click once on the
image in the preview window. Click print and compare the results.

Results:
The first printout is smaller than the second printout. (The deviation from
first printout to the second is alarmingly large)


Follow up tests:
1.We replicated the same steps in I.E. and both the printouts came out to be
exactly same.

2.We replicated the same steps in Opera and both the printouts came out to be
exactly the same.

3.We replicated the same steps but now instead of having “Scale” as 100% we
chose “Shrink to fit page”, and then exactly followed the procedure listed
above. The resulting pages again showed inconsistency as they had without
selecting the “Shrink to fit page” option.


Importance of the bug:
1.Since the contemporary browsers depict a consistent printout behavior
irrespective of the circumstances depicted above, hence users might easily opt
to work with other browsers.

2.Since the “Print Preview” and “Print” are the vital functions of any browser,
any deviation from expected (user’s expectation) behavior can easily lead the
user to rethink about using the browser. This definitely serves harmful to the
browser integrity.

I recommend using pdfcreator to test this bug.
This way you wont need any paper to test this bug. 
You can find pdfcreator on:

Ok, we have multiple confirmations. Confirming for now. Moving to Browser-Print
Preview, since our code is the same.

this WFM, _if_ the bug is preview is not same as printed page.

http://www.largeformatphotography.info/qtluong/sequoias.big.jpeg using same margin size, 100% scale, image at full size - printed page identical to print preview

hp4650 printer
same results for FF 2.0.0.9 and trunk - Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9b2pre) Gecko/2007112605 Minefield/3.0b2pre

a second issue, is only the first page is printed - picture ends at bottom and right margins, with no additional pages

The bug as originally reported is not happening anymore,
but now i get other wrong results for large images:

using Mozilla/5.0 (Windows; U; Windows NT 5.1; nl; rv:1.8.1.10) Gecko/20071115 Firefox/2.0.0.10:

1. First set in print preview: fit to paperformat
2. Go to http://www.largeformatphotography.info/qtluong/sequoias.big.jpeg by
example.
3. click on the picture, so that the pictures isn't sized to the size of your
screen.
4. Now choose print preview and choose scale 100 percent.

Bug 1: the print preview doesn't get updated, to 100 percent; first i have to change it to something different (ex. 50%) and then to 100%
Bug 2: fit to paperformat doesn't nicely fit the page to the paperformat
