Alistair, can you do the following test:
Deactivate blacklisting and also do no force uni-directional mode.
Cancel all jobs and power-cycle the printer.
Run the following commands in a terminal window:
lpstat -v
sudo /usr/lib/cups/backend/usb
sudo /usr/lib/cups/backend/usb
(it is correct that I ask you for the same command twice) and post the
output here. Is the output of the last two commands the same (should
be)? Does the URI ("usb:/...") match the the one of the first command?
power-cycle the printer again. Do the following sequence of actions:
1. sudo /usr/lib/cups/backend/usb
2. Print a job
Repeat until the job hangs (should be the second time).
Now cancel the job (but DO NOT power-cycle the printer) and run another
sudo /usr/lib/cups/backend/usb
Post the output of all commands here
Cancel all jobs and power-cycle the printer again. Repeat the two tests,
but running
lsusb
before each
sudo /usr/lib/cups/backend/usb
and post all command output again.
Also attach the error_log files of all these tests.
