lprm hangs printer

[Steve Hubert]

I presume that this is a well-known problem, but I have not
seen a fix or an explanation for it myself.  When the 4bsd (4.[23])
line printer spooler is printing a job and you lprm the active job
it will hang the printer queue as often as not.  Has anyone looked
into what is happening and perhaps come up with a fix or am I doing
something wrong that is causing the problem?

Also, when the system crashes while a job is actively printing the
queue will often be hung after reboot.
