Did you upgrade to 4.0 or 4.0.1? If only 4.0, the serial ports are broken,
very broken. (If 4.0.1, they're only mostly broken -- a big improvement). 

What you're seeing is when the printer port is closed the last block is
being zapped instead of flushed to the printer. You can get around it by
putting something like this in your rc.local:

    sleep 10000000 > /dev/ttyb

What this does is keep the port open so it doesn't prematurely close and
delete that last block. Better would be to get the serial port patches from
Sun (some are on 4.0.1, but that's not a complete set) and get them
installed. Perhaps by now *all* of the serial port bugs are fixed.
