Remove paper size options on node add forms Node add forms show some paper size options no matter who the user is, even regular authenticated users. It seems to be part of the Printer, email and PDF versions module. 

I added the following code to my helper (let's call it my_helper) module, as suggested here:

/**
 * Implements hook_form_alter().
 */
function my_helper_form_alter(&amp;$form, &amp;$form_state, $form_id) {
  // Hiding the print fields that print.module puts into the node form.
  if (strpos($form_id, '_node_form') !== FALSE &amp;&amp; !empty($form['print']['print_pdf'])) {
    foreach ($form['print']['print_pdf'] as &amp;$print_field) {
      $print_field['#access'] = FALSE;
    }
  }
}


I am also using the Simplify module to hide certain form elements but this isn't coming up as an option there.



Edit: I looked at the system table in MySQL to see that the weight of the module was 0, so I added a .install file to change the weight to 10. But still not seeing an affect.

   function my_helper_update_7100() {
        db_update('system')
        -&gt;fields(array('weight' =&gt; 10))
        -&gt;condition('name', 'my_helper', '=')
        -&gt;execute();
    }

  I just fixed this on my works web site. The form alter code needs to be added in an #after_build callback as the paper size and orientation fields don't exist yet in the form array in using hook_form_alter. Here is a complete example.


/**
 * Implements hook_form_alter().
 */
function my_module_form_alter(&amp;$form, &amp;$form_state, $form_id) {

  // Hiding the print fields that print.module puts into the node form.
  if (strpos($form_id, '_node_form') !== FALSE) {
    $form['#after_build'][] = 'mhfa_pdf_form_alter_after_build_remove_print';
  }
}

/**
 * Remove pdf print controls.
 */
function my_module_form_alter_after_build_remove_print($form, &amp;$form_state) {
  unset($form['print']);
  return $form;
}
