First off, I can include log files (and I will) but they're not going to
help out at all; the problem that I am having does not log.

I can configure USB printing just fine via the web interface.  However,
once the printer is setup, it does not print.  It kicks off the
Ghostscript process, and kicks off the USB back-end, and does nothing. 
The USB backend then becomes idle and will not die on signals 9 or 15, and
I find that I have to send it a signal 11 to actually kill it.

This on FreeBSD 6.2, CUPS 1.2.7, ESP Ghostscript 8.15.3.

The printer /almost/ works using the “file” backend, but it is
unreliable and needs a lot of hand-holding.  If a print job is cancelled,
the printer does not print subsequent jobs correctly, and I have to
restart the printer.  When I turn the printer off, its USB device node
disappears and CUPS appears to bail out.  So, when I cancel a job, in
reality I have to cancel a job, power-cycle the printer, and then restart
CUPS.

If you need anything I will try to provide it.  I don't know why the USB
back-end isn't working—I can cat files to the printer just fine (PCL
files; it's a PCL printer that speaks PCL 5 and PCL/XL).
