Font installing procedure

I am trying to "force" a font into my site. The effect is to have a system display a font even if it is not installed on their computer. I have done this on http://elizabethrosecorsets.com,an html/css site to get the Papyrus font to show even if not on client side.

The code:
@font-face {
font-family: Papyrus;
src: url("Papyrus.eot") /* EOT file for IE */
}
@font-face {
font-family: Papyrus;
src: url("Papyrus.ttf") /* TTF file for CSS3 browsers */
}
in the css file, with the noted files in the same directory works just fine for the effect the client wanted. Now she wants the same effect in an Atahualpa site.

I have tried putting the code in the style.css file and putting the noted files in the same directory, to no avail. Any ideas, or is this just not feasible?
