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.
