maybe because the page wasn't requested by a browser but by your printer
version script, therefor HTTP_ACCEPT_LANGUAGE can't have the language
preferences defined in the visitors browser.
why don't you use different css settings for browser/printer version of
your pages? i guess the content of the page is the same; font size or
background images or table widths are the values you want to change.

pozdrawiam.

On my site I have a code based on $_SERVER['HTTP_ACCEPT_LANGUAGE'], to
selelect language variable:
if(!isset($_SESSION['lng'])) {
if(preg_match("/pl/i", $_SERVER['HTTP_ACCEPT_LANGUAGE'])) {
$_SESSION['lng'] = "pl";
}
elseif(preg_match("/en/i", $_SERVER['HTTP_ACCEPT_LANGUAGE'])) {
$_SESSION['lng'] = "en";
}
elseif(preg_match("/de/i", $_SERVER['HTTP_ACCEPT_LANGUAGE'])) {
$_SESSION['lng'] = "de";
}
else {
$_SESSION['lng'] = "en";
}
}

There is also "printer version" script which read the site like this:
$refpage = (phpversion() > "4.1.0") ? $_SERVER['HTTP_REFERER'] :
$HTTP_SERVER_VARS['HTTP_REFERER'];
$read = fopen($refpage, "rb");
while(!feof($read))
{
$value .= fread($read, 16000);
}
fclose($read);
....
print $value;

I have a problem, because site processed like that is loosing it's
language variable. Pice of code, which is selecting langage, doesn't
work, because variable $_SERVER['HTTP_ACCEPT_LANGUAGE'] is empty.
Maybe someone know why ?

My "printer version" script is cutting pieces of code between <!-- start
--> and <!-- stop --> markers from the input file, so I can decide which
pieces will be available for printing. Unfortunately it's loosing
language settings and that's my problem.

The web server is sending the request for the referer page, not the web
browser, and will only pass on a GET request, not all the other parts of a
HTTP request that a normal web browser would do.

Two ways to tackle this. If you have it available use curl to fetch fetch
the page. Otherwise, store all the browser information in a session
variable, then call the printer page.
