I was thinking it'd be nice to have different characters than the typewriter-tastic letters that we have for default.
It would need a font selection gui, an empty set of decals, and a script or two (possibly an external non-Torque-based script)
It works like this:
Once the font is selected, the script would break the font file down into component characters. It would trace each character of the font and then dump each trace into a blank placeholder "image" so that the printer gun can use it.
Discuss, hate, rate, bash noobs, or carry on however you will.
