I don't know much about LW and it might as well be a line (ttyd) problem
as you point out but when debugging Postscript printer problems
I often found it useful to do a 

cat -u /dev/ttyd1 >/var/log/PS-log (e.g. in /etc/rc.local)

and later do a

tail -f /var/log/PS-log

while sending jobs to the printer to see any anomalies. Might it have to
do something with ^D being required for the LW at the end of a file or not?
