Don't use an output filter.  LPD will start an output filter to print
the header page.  It then sends the magic sequence \031\001 and will
wait for the output filter to suspend itself, which ttcp or the script
that's calling it will never do.

Instead, just use an input filter *only*.

/etc/printcap:

lp0|lp||rlp|lw|ps|postscript|PostScript|lp1|lw1|postscript1|PostScript1:\
        :lp=/dev/null:\
        :mx#0:\
        :if=/usr/local/bin/printe:\
        :sd=/var/spool/printe:

/usr/local/bin/printe:

#!/bin/sh
exec /usr/local/bin/infilter | /usr/local/bin/ttcp -D -t -p 10001 10.0.0.64

Finally, ttcp is really hefty for this, but it should work.  About 10
lines of perl in the handbook under `Printing' should also do the job.
