I have seen this happen (by similar accident) on a phototypesetter at
high resolution, generating maybe fifty pages of program listing in
Courier at 2540 dots per inch, instead of the one page of nice graphic
output.  I think it might have been a result of some font-proofing
software I was writing in which I forgot the initial %!  That's the
kind of thing you forget only once.

Actually, I vaguely remember TranScript getting an option added to it
to deal with things like typesetters where you NEVER want the program
listed in Courier.  Maybe it was the $PSTEXT environment variable, so
you could at least do the null filtering operation rather than convert
it to text for listing.

Gee, this has really become a tangent, hasn't it?  I like it when that
happens....
