I have a Brother Printer (HLL2935dw) that will not print, which I expected to happen after adding the printer and driver through CUPS.
Release is Ubuntu 20.04.1 LTS
Package is cups: 2.3.1-9ubuntu1.1
Instead of printing, the process hangs until the I cancel the print job.
Output of the CUPS error log. Debugging has been turned on.
Error log output:
