Is this also true of the Linux version of Putty? I've never used it but it's packaged in Debian. Also I wonder what it is you mean with "bidirectionally" here. Do you expect to read data from the printer and send it back? Another thing I found with a quick search is screen. While screen is a terminal multiplexer, it has a user controllable setting printcmd for printing: "printcmd [cmd] If cmd is not an empty string, screen will not use the terminal capabilities "po/pf" 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 a command 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." >From that description you should be able to set printcmd to for example cat > /dev/ttyUSB_whatever and the remote printing will go there.
