If you're really determined to keep using it, you'll find it easier to write
a filter programme than hacking the printer's ROM. In fact you may well find
almost anything is easier.
Modifying the founts isn't quite so bad - if you write youself a small
screen editor, you can step through the existing ones and modify where
needed. I did this once with a Brother 1109 (or was it 1209?) - it wasn't
much fun finding the base. Try searching for 7 0x00 bytes contiguously,
if you're lucky there'll only be a few, and one will be the start of the
space character bitmap.

Good luck, you'll need it!
