Send by email will only send full view of node, not teaser or settings in 'print' view_mode

I'm trying to send node 'teaser' or custom content from node ( by addind 'print' view_mode for content type) by mail but it will always send 'full page' of node.

It seems that in print_controller() the _print_generate_path() method will always be called (!) and thus the full node view will be rederd in mail body.
As a test i replaced the '_print_generate_path()' method with '_print_generate_node()' method and supplied the nid as param, but in this case the mail was empty.

I just use the Send by mail link button provided by the module (which opens page: /printmail/), fill in the form, and send; other than that only basic configuration (i use the SMTP Authentication Support module )

Thank you.
