Brother printer refuses to print.

I've tried everything: restarting, unplugging, switching from WiFi to direct cable, restarting my computers, deleting files, restarting spooling, nothing works. It worked perfectly for about 3 months, then stopped working.

Brother MFC-J6555DW printer. Working on multiple computers, Windows 10 Home, Version 10.0.19041, Build 19041.
