Comment 5 for bug 219922

I've noticed that Firefox doesn't print exactly Letter when you select A4. It seems in my case that it simply prints the contents too close to the top edge of the sheet, so a large white margin at the bottom appears, and so it looks like a Letter output.

Maybe is it a problem of content not being correctly centered?

I'm attaching a photo of the output I obtain with both Letter and A4 settings.
