Print module doesn't work with Panelizer module. Why? I need to make print pdf module work on the panelizer node. But on page printpdf/node/nid, I see only the node title and panelizer field is not shown.
How to fix it?
The Print module uses hook_preprocess_node which is not used with panels_everywhere/panelizer. In a similar issue (with panels everywhere) I  used a patch 565856-panel_support_print-39.patch. 

Background discussion and the patch you can find here:

Hope this will help.
