@ray326Jan 03.2008 — #Courier is a "clean" monospaced font but you can look around the web for free fonts that look like a "real" (aka "banged up") typewriter if you'd prefer "dirty."
@ray326Jan 06.2008 — #What you have there is a scan, not the output from font. There is no font or non-custom renderer that will randomize the character damage like that. If that is literally what you need then it's time to whip out your favorite programming language and do a little image processing code.
