Thanks to everyone who responded. (,
Chris.Drake@Corp.Sun.COM, oconnor!,
and as always, It turns out that the problem
was exactly what no one suspected. My copy of /usr/lib/lpd was

I grabbed a copy of it over from another system and everything has
been working beautifully since then. Seems pretty strange that
lpd was only corrupted a *little bit*. That is, everything worked
ok except the part where it was supposed to rename the tf files
to cf. It turns out that yes, there was a disk problem that day,
but it happened after the problem with lpd.
