Gecko-based browsers show the Print stylesheet

Why does it do this for my site, but not alistapart, or other sites?

[Llama]

My site shows the print stylesheet, rather than the screen or projection stylesheet (I use the same stylesheet for both) when using either

<style type="text/css">
@media "print" { @import "http://www.mysite.com/print.css"; }</style>

or

<link rel="stylesheet" type="text/css" media="print" href="http://www.mysite.com/print.css" />

I'm using the 2nd method for both Screen and Projection.

Thanks for any help.

Should be :
<link rel="alternate stylesheet" media="print"...

or :
@import url("foo.css") print;

or:
@media print {
...
}
