I suspect that may have been the case here, but this is a mere Epson C82, 
whose memory buffer probably can't hold more that one sweep of the head 
out & back.  It actually surprised me that it could print ascii text!

It may be that I'm approaching the end of this old warhorse C82, I've had 
it crash and require a pull the plug powerdown 3 times in the last couple 
of months, more often since I installed FC6 TBE.

But this exact scenario, where the whole system has had to be rebooted 
after cleaning up the job files to actually stop the printer is something 
I've railed about from the gitgo years ago.  It seems to me that there 
should be (this IS a packet protocol printer) a way to force a software 
reset and buffer flush so it stops in its tracks, spitting out the 
unfinished current sheet just to clear the paper path and return then to 
the idle state.

Can this not be done as part & parcel of the job kill?

And its typically doing the crash when a powerdown from the front panel is 
attempted while its busy.  That was the case in this instance also.  At 
times I'd kill for a genuine power switch.  Finding its power cable on 
the strip to unplug it is a PITA.  You wouldn't believe my power 
distribution here, its all from one wall plug, but I haven't had a modem 
or anything else destroyed by a lightning strike in the years since I did 
it.

I have a C88 also, but it has had paper feed issues (crooked sheets bend 
the bottom corners over, even in 40-60 lb photo papers) since it came out 
of the box, and the color is horrible compared to the well tuned state 
the C82 drivers are in.
