[plt-scheme] Slightly OT--How to print from DrScheme using CUPS

Could anybody tell me what print command or symbolic link trickery I
can use to get DrScheme to print using CUPS?

Right now, we print to a file, open the file in Evince, and then
print. I've thought about allowing direct printing for a while, but
every time I look it up, I run out of time before I can find an
answer.

Thanks,
Todd
