I think I managed to trick this thing to work. Steps
1) Try to print something, it'll fail
2) Detach and re-attach the USB end of the printer cable (do NOT reboot the printer)
3) Now printing magically works
If I now reboot the printer, it'll stop working (at least I think it did so. It is almost 2 am and I'm not at my sharpest) and I need to re-do the cable re-attach.
