Here are two little sed filters I use for turning nroff-style
backspacing and underlining to Epson equivalents. Before running
substitute a real escape character (ASCII 27) for <ESC> and a real
backspace character (ASCII 8) for <BS>.
--snip--
# eps_ul - change from char backspace underline underlining to epson
# escape sequences
sed \
    -e '/_<BS>\(.\)/s//<ESC>-1\1<ESC>-0/g' \
    -e '/<ESC>-0<ESC>-1/s///g' \
$*
--snip--
#
# epsbold
#
# Filter to turn nroff-style bolding (i.e. by backspacing and
# overstriking) into the escape sequences required for an Epson
# printer. See also nobold, which strips out the bolding, and
# no_ul and eps_ul which do the same for this method of
# underlining.

sed \
    -e '/\(.\)<BS>\1<BS>\1/s//\1<BS>\1/g' \
    -e '/\(.\)<BS>\1<BS>\1/s//\1<BS>\1/g' \
    -e '/\(.\)<BS>\1/s//<ESC>E\1<ESC>F/g' \
    -e '/<ESC>F\( *\)<ESC>E/s//\1/g' \

You can extend this in various ways as required.

If you find a way of doing the ^L, I'd be interested.
