My printer (Brother MFC-J895DW) worked with F35 using a dnssd URI. When i updated to F36, this didn’t work (printer offline). I reinstalled the printer, but the only URI shown was a lpd://BRW5C619963D0FE/BINARY_P1. This doesn’t work. I bought a USB printer cable. Plugging in the USB cable didn’t bring up a ‘add printer’ dialog nor does it show in system-config-printer or the CUPS web interface (localhost:631). It does, however, show in syslog (journalctl) and lsusb. So why can’t I add a USB printer? Or, a network printer that works?
