Print Links in $content variable

Hi Drupalers,

I have the print module in my site. Print links are rendered into the $content variable.
But, I can't find the print links in $content in mytheme_preprocess_node().

My goal is to place the print links anywhere I like in the template file, but print links are included in the $content variable in theme level.
How can I separate the print links from the $content ?
Any idea ?
