Well, this will work, but it doesn't really fix the problem, it just
patches the symptom.  The problem is in the code for lprm, he tries
to restart the printer and uses the variable containing the hostname
INSTEAD of the variable containing the printer name.  It's pretty
obvious when you look through the code.  The fix above DOES fix the
problem, though, and if you're not into patching code, and if it
doesn't cause any other problems, it'll do.

The REAL fix, is to /usr/src/usr.lib/lpr/rmjob.c as follows:
92c92
<       if (assasinated && !startdaemon(host))
---
>       if (assasinated && !startdaemon(printer))
