[2002.03.21] Debbie Sontag contributed a solution if the page that you are trying to get printer-friendly is password protected using HTTP authentication: 

REPLACE THIS LINE:
$request = "GET $document  HTTP/1.0\r\n\r\n";

WITH THIS:
$request="GET $document HTTP/1.0\r\n";
$request.="Authorization: basic  ".base64_encode("username:password")."
\r\n\r\n";
Thanks Debbie!
