Ok, got the siuation now.

My interpretation of the 'lsusb -v' output is that this printer does not
understand the IPP-over-USB protocol. Driverless printing with it is not
possible.

You have installed the free printer-driver-brlaser. According to

  https://github.com/pdewacht/brlaser

the Brother HL-L2320D series is supported by this driver. You should read
the open and closed issues and decide whether you wish to raise your own
issue.

An alternative is to delete the existing print queue and set one up with
the non-free Brother drivers.

Cheers,

Brian.
