PrinterFriendly in v6.34

Okay, here goes, if there is a long post, and the  "Printer Friendly" link is clicked, the post cuts out the top and bottom of the post keeping the post headers in tact.  The normal post display contains the complete post, but the truncation occurs every time in the "PF" version. I have looked around and around but perhaps I am just blind. Where are the settings to address this issue?? or the code lines?

  Thanks
