How to set margins 0 on print preview?

Question

Where am i doing wrong?

This is the normal print preview:

Answer 1

I'm prevented from upgrading a computer from Windows XP to something more recent, so basically I'm stuck with IE8.

I found that on IE8, page margins will always be a minimum of 6.01mm left and right, and 5mm top and bottom. No matter what I do, even using @top-left right and centre rules inside the @page rule, it will still default to the values above.

It may be easier to create the stylesheet to take into consideration this limitation on the print size.

It may also help to put the IE hack \9 in front of the CSS class property value, duplicating the property may also help in some cases, (but won't affect the margins of the page), such as:

.aDiv {
    margin: 10mm;
    margin: 15mm\9;     //this \9 hack will set that value only on IE8.
}

I know there are other hacks similar to this, such as \0 but I admit don't fully understand them. \9 works for me in IE8 in some situations.
