Ok, good.

I used a trick where you count the entries in /proc/scsi/scsi and the
entry number of your device is your sg number.

Now, it looks like I'm getting a SCSI error when I try sending a job.
I've been able to send jobs to non-scsi postscript hp lj8000 via
jetdirect from this system in raw and foomatic configurations, so my
base setup is working to some degree.

I changed my logging from info to debug2, but it didn't give more info
on the scsi error produced.  Is there anything I can do to help you
diagnose the problem?

Thanks,

Mike
