Yes.  Check out Ghostscript in /usr/ports/print.  Just a couple of
days ago, I configured a Canon BJ200e to emulate a Postscript
printer.  This is just a guess, but I wouldn't be surprised if the
BJ-240 is backwardly compatible with the BJ200.  In any case,
Ghostscript supports most common printers.

Here's an example of how you could invoke Ghostscript.

#!/bin/sh
#
# pstobj200if - Print Ghostscript simulated PostScript on a Cannon BJ-200
#

exec /usr/local/bin/gs -dSAFER -dNOPAUSE -dQUIET -sDEVICE=bj200 \
        -sPAPERSIZE=letter -sOutputFile=/dev/fd/3 - 3>&1 1>&2 2> /dev/null


You can change the paper size to A4 if you wish.  Also, the juggling
of file descriptors is necessary to keep error messages separate
from the actual printer output.  (-dQUIET unfortunately isn't
enough.)

If you haven't done so already, you may want to read section 7 of
the FreeBSD Handbook which explains printing.

Have fun,
Aaron
