Only in IE3 <g>.

Per CSS-1, a pixel is to be scaled to 1/90" when the resolution of 
the output medium is "significantly" different from that of, well, a 
display with 90dpi physical resolution. This suggested value has 
apparently been amended since to 1/96" in committee, making 1px = 
.75pt for high-res output (e.g., print).

It's been a while since I checked, but I think NS4 had been scaling 
pixels to 1/120" for print. I know that MacIE5 does the right thing, 
scaling to 1/96".
