The Margins fields in the Print / Page Setup dialogs are inaccurate, perhaps
because of hardcoded defaults which are added to the values entered here.  This
is no good.  Some print-enabled web applications require precise control over
margins and page layout.

Reproducible: Always

Steps to Reproduce:
1.  View the sample page
(http://windmillcycles.com/mozilla/mozilla_print_margins_bug.html).
2.  Set your margins to 0 and headers/footers to blank, then print the sample page.
3.  Take a ruler to the sample page.

Actual Results:  
The sample images are approximately .25in further right and lower than where
they should be.

Expected Results:  
The sample images should be located exactly where they were intended to.  That
is, if a user specifies a margin of 0 inches, give them 0 inches.  If a user
specifies .5 inches, give them .5 - not .75.

I believe this bug is really only an "issue" for those who wish to create very
strictly formated documents that are primarly for printing.  That is, documents
whose elements are positioned with absolute values in inches, millimeters, etc.
 While this is obviously not a majority, I think it should be supported.

The positons are off by 3/16in to the right and down. (+-1/16in)  Standards mode
didn't change anything.

I believe this bug report is about the hardcoded 1/4-inch margin built in to the
PS printing module, which is additive with the margins set from File->Page Setup
and File->Print->Properties. Differences on the order of 1/16in may be due to
adjustments performed by CUPS.

I have a patch ready for bug 175879 which incidentally removes this 1/4-inch
margin. I haven't submitted the patch yet because it'd likely bitrot before it
was reviewed. Stay tuned for further updates.
