Since dumps don't like being written out to a partition on a RAID1 set, this is about the only kind of trace I could obtain: http://www.puresimplicity.net/~hemi/Pics/Misc/trace.jpg For what it's worth, I moved the printer to another machine and removed the USB-to-parallel adapter that was the catalyst of the problem. If anyone cares to work on this problem I'll be more than happy to send the cable on a one-way trip to any interested party in order to help get the problem resolved. If anyone's interested in the cable for testing, etc. just let me know.
