Colin, it's working again, here's what I did.
1)Blew out connector on both ends of USB cable and on printer.
2)Plugged into front port on PC, still got 'Waiting for printer to be
available'.
3)Turned off printer, plugged into 7 Port USB Hub, turned printer on. It
initialized immediately. Brought up CUPS web interface, printed a test
page with no problem. Waited an hour or so and printed another. Just to
be sure I printed another this morning. 

So far it seems to be working fine again. I really won't know until I
have to reboot for some reason or another I guess to see if it's picked
up again. I'm back to running the latest 3.13 kernel again as it's
possible that when I was asked to run the 3.19 version that something
may have gotten borked though it did print when I had it running.

Guess now I can print off the 'kernel bisection' information and get to
work on that though the latest seven 'lockups' no longer mention the
'kernel: [ 8248.820016] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck
timer elapsed... render ring idle' issue.

Thanks for all the assistance Colin, hopefully the system will be stable
for awhile.
