Description

14 years ago
User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6) Gecko/20040206 Firefox/0.8
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6) Gecko/20040206 Firefox/0.8

When a page is printed with extreme scaled values the printout is not as
expected (clipped or missing data). (refer attachment)

Also the scale input fields in 'Print Preview' and 'Page Setup' are not
synchronized. (refer attachment)

Reproducible: Always
Steps to Reproduce:
1.On the print preview page, select the custom scaling option on the top center 
of the menu bar. Select the custom option and enter any value above 500. Now 
visit the page setup option on the top left corner of the menu bar and check for
the scale input field.(make sure that shrink to fit page is unchecked)
*You will notice that the two values are different. 

2. Set the scale size to 500% from the page setup option and send the page(s) to 
print. 
*The resulting printout will be incomplete.
	
3. Set then scale size to 10% from the page setup option and sent the page(s) to 
print. 
*The resulting printout will miss out certain content.
	
This misbehavior can be observed even if the ‘Print background’ option is
checked or unchecked.


Actual Results:  
1. The scale values from the custom option on print preview is different from
the one that is stored in the page setup option. However if the scale value is
changed from the page setup option then the value in the custom option in the
print preview is the same. (refer attachment)
	
2. The resulting printout misses a lot of content, rather only left most area of
the web page that can fit on a single page is printed page by page. The
remaining is just simply left out.
	
3. The resulting printout misses a lot of detail and data.


Expected Results:  
1. The two scale input fields should have the same value irrespective from where
they are set. 

2. The scaled page should be printed as expected (presumably spanned across a
few pages).

3. The scaled page should be printed with the content in the right location
(presumably very small), but not missing.

Follow up tests:
----------------
1. Replicated the same bug for small pages and pages with lesser content,
however the problem persisted.

2. Replicating the same steps on I.E. did not reproduce the bug. I.E. allows the
print preview to range from 10% to 500% but the resulting printout is well
within and as per the margins specified. (In a way I.E. imposes constraints on
the way a page can be printed to avoid such issues).


Importance of the bug
----------------------
1. Since Firefox is not an image editor, one would not expect it to fulfill the
requirements and expectations that an image editor would have. However being
able to manipulate printouts (scaling factor) by changing the scale and then
receiving unexpected output by being able to print the change (no constraints
like I.E.) leaves Firefox in the middle of providing an additional feature but
not being able to fulfill the expectation from that feature.

Unsync. Scale Input Fields

This is an example of the synchronization of values between the two scale input
fields that is discussed in the bug report.

Example of when the scale factor is 500%

This snapshot shows that the scaled (500%) page prints out exactly what is
shown on the print preview and just forgets (leaves off) the rest of the page.

Missing Data/Content example when scale factor is 10%

This snapshot shows that the webpage that gets printed has missing data
(exactly as shown in the print preview).

This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
Thank you for your help in this matter.
