Comment 7 for bug 55293

Of course, fixing bug 284925 would make the margins set automatically, but the display of measurement units (this bug) is a separate issue.

What's strange, I've determined that the "Gap from edge
of paper to margin" setting only allows values from 0 to 0.5, and in my case changing it doesn't affect the printout visibly.

Is this setting changing anything at all? What is its relationship to margin settings in Page Setup? http://kb.mozillazine.org/PostScript_Module seems to imply that the gaps are only for headers and footers.

Bug 130075 sheds some light on the issue, but it doesn't dispel all the confusion.
