Thanks Till! I removed the blacklist and loaded the module.
Now I see the printer, but there's no printing at all when sending the test page (it says it's printing, the job gets into the queue, disappears from there, and I even get a notification that the job was printed), but no printing at all.
Attached here are all the normal info (seeing the permissions in /dev stuff, I even tried relaxing the permission in the devices, but the behaviour is the same).
