screen: Printcmd

 
 20.15 Printcmd
 ==============
 
  -- Command: printcmd [CMD]
      (none)
      If CMD is not an empty string, screen will not use the terminal
      capabilities 'po/pf' for printing if it detects an ansi print
      sequence 'ESC [ 5 i', but pipe the output into CMD.  This should
      normally be a command like 'lpr' or 'cat > /tmp/scrprint'.
      'Printcmd' without an argument displays the current setting.  The
      ansi sequence 'ESC \' ends printing and closes the pipe.
 
      Warning: Be careful with this command!  If other user have write
      access to your terminal, they will be able to fire off print
      commands.
