Oliver,
Thanks for your response. This is consistently reproducible and the printer
will get to ~20% down the first page before stopping. Just when or after it
stops printing, I observed the system time jump to 61% [2], then some
polling/logging going on, until I turn the printer off or disconnect the cable. This
can be seen again in the logs [1], but we do not observe your additional
debugging. I enabled the additional USB debugging also.
