What is the variable for the human readable name of the node type?
You can use the node_type_load() function to load up the node type object, and then extract the name:

$type_obj = node_type_load($type);
$name = $type_obj-&gt;name;


You can integrate with your current code like so:

&lt;?php
  $type_obj = node_type_load($type);
  $human_readable_type = $type_obj-&gt;name;
?&gt;

&lt;?php if ($display_submitted): ?&gt;
  &lt;div class="submitted"&gt;
    &lt;div class="submitted-type submitted-item"&gt;
      &lt;?php print $human_readable_type; ?&gt;
    &lt;/div&gt;
  &lt;div class="submitted-author submitted-item"&gt;
    &lt;?php print $name; ?&gt;
  &lt;/div&gt;
  &lt;div class="submitted-date submitted-item"&gt;
    &lt;?php print $date; ?&gt;
  &lt;/div&gt;
  &lt;div class="submitted-comments submitted-item"&gt;
    &lt;?php print $comment_count; ?&gt;
  &lt;/div&gt;
&lt;/div&gt;
&lt;?php endif; ?&gt;
