Alternate option for printing HTML docs

Hallo,

I made a HTML page with the following lines:

<LINK REL="stylesheet" media=screen type="text/css"
href="/css/formulier.css">
<LINK REL="ALTERNATE"  media=print
href="http://imecwww/~tcit/en/formulieren/pp.ps"
TYPE="application/postscript
">

I use netscape 4.06 UNIX. When I print the html document
it does not print the Postscript file. 
The output (fonts are different) is different when I print the
postscript file
directly (lp pp.ps -d....).

What is the reason?
