I have this page made in Xara, which is 950px wide and 2500+px tall.
It centers when the window is wider than 950px.
The problem is that when printing this page, from Opera, Chrome or whatever browser I use, it does not print well unless the windows width is scaled so that the page fits exactly inside it. Otherwise a wide left margin is added, with the same width as the margin on screen, and the right side may be clipped.
I would really like this to print left-aligned, with no margin at all, except for a narrow printer/paper margin.
How can I achieve that in Xara (Designer Pro X11)?

And how could I create a web page that is left aligned - and not centered automatically?
