Is this a problem with a current (1.6a trunk) build? I believe this was fixed a short time back...

No - it's version 1.4 like specified. When it's fixed now it's fine!

even when i zero all borders, i still see a 15-20mm margin all around in 1.6a

I too have noticed issues with the left and right hand margins, particularly the right. If I have a page FULL of text (i.e. 100% width on a table), the right margin of the text is cutoff. I try using CSS to change the padding and/or margins, but that only cuts off more text. If I set my margins to 0 in the Page setup, then I'll get all my text, but the printed page now has smaller margins than what is really necessary and barely a margin at all. Furthermore,a 0 margin should mean 0, period, when it's really more like .5" on all sides (printed that is).

What this looks like to me is the preview and output is adding 0.25" to all sides. If you enter a margin of 0.5" in the you'll end up with 0.75" margins. It appears that the preview window is accurately showing what the printer prints. We just have in accurate numbers in the dialog box.

Now I'm using Gecko/20070914 Firefox/2.0.0.7. The problem still persists but has become a little bit better. With margins of 10, 40, and 0 the margins to the edges are always 5-7 mm to large (left: 7, right 6, top and bottom 5; 4-5 mm are outside the printable area). When I specify a margin of 20 mm I expect to have 20 mm, not 20 mm plus the width of the unprintable area. (In print preview, the margins left, right, and top are even 3 mm more than on paper - 3 mm are calculated with respect to the real paper width of 210 mm.)

Unfortunately this is somewhat difficult to test as a real printer (unwritable margin) is needed. I did test the following: - The pdf from bug 1448395. PDF.js sets @page margins to 0 so now this printout lines up perfectly with output from Acrobat. - A modified example from bug 963557. I set the page margins to various inch widths and and measured everything on real paper. One thing we may want to change is the various references in the windows printing code to printable(Width|Height)InInches. This would now be more accurate if it were something like physicalWidthInInches or pageWidthInInches. I'll defer to the reviewer if we should change this.

sorry I'm taking so long to get to this review. The changes look complex, need to find some time to dig through this. If you're3 pressed to get this landed please ping me, I'll try to find someone else to do the review.
