minified/concatenated CSS is forced with media="screen"

[aurmil]

when using this module, the CSS is included with "media" attribute set to "screen"
this is done in Minify_View_Helper_HeadLink:

$this->prependStylesheet($this->view->url(array('key' => $key), 'minify_css', null, false, false)):
...
$this->prependStylesheet($this->view->url(array('key' => $key), 'concat_css', null, false, false));

so "@media print" styles in the CSS file are useless as they are not considered when printing
you should not assume what the user / dev wants to do and leave the choice or add a way to automatically determine the media type to set (eg: loop on every CSS included and set the less specific type you find)
