Book printer friendly pages has 'Add Comment' all over

I've tested this on a clean Drupal 7 install locally using the Devel patch #303143: Generate hierarchical books using the UI not drush to generate 500 nested book pages.

The comment links are not visible so guess this is d.o specific.

I'm not sure how I can help any further now.

A core hack works but I needed to find the real cause.

 function book_node_export($node, $children = '') {
   $build = node_view($node, 'print');
+  No need for comment links
+  unset($build['links']['comment']);
   unset($build['#theme']);
   // @todo Rendering should happen in the template using render().
   $node->rendered = drupal_render($build);

The title for the comment link is comment/comment.module: 'attributes' => array('title' => t('Share your thoughts and opinions related to this posting.')), which has some logic not respecting 'print' view mode

          if ($comment_form_location == COMMENT_FORM_SEPARATE_PAGE || (!empty($node->comment_count) && user_access('access comments'))) {

coming from #754760: "Add new comment" appears directly above comment form / "post comments" does not work without "access comments" permission.

Removed the misc/print.css

A quick fix would be to hide the inline links which are generated by the book module.

// misc/print.css
ul.inline {
    display: none;
}

Just tried https://drupal.org/book/export/html/2127611 to review #3

The patch done in #2141929: Comment link or form is added to print view mode. hides the the comment link when using the 'print' view mode.

I do thinks ALL links should be dropped when requesting a printer friendly page. Ie Facebook share or flag links should not be displayed either. Fortunately we do not have these or the modules do it right?

Below a snippet from the mentions export page above.

<ul class="links inline"><li class="comment-add first last"><a href="/comment/reply/2127611#comment-form" title="Share your thoughts and opinions related to this posting.">Add new comment</a></li>
</ul>

Please review #2141929: Comment link or form is added to print view mode.
