Total newbie here. After the latest updates, my printer doesn't work anymore. I tried all sorts of debugging and troubleshooting, reinstalled CUPS, up to the point I ended up like: https://i.imgur.com/nnu84s2.png
But even after fixing that, the printer doesn't work. Brother printer support told me it's none of their business and it's an OS problem. This is the error msg, when I try to clean heads: {'cups_connection_failure': False} printer doesn't work - Debian User Forums and none of the fixes from there helped (considering I did them right).
If someone is available to do a Team Viewer session and help, I would appreciate it, cause at this point the only thing remaining is to bang my head on the wall.
