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.
