I forgot to mention that the Installed Version of Package
"printer-driver-brlaser" is 3-5~ubuntu1
My initial hunch is that 3-5~ubuntu1 may not be up to date with the latest
developments that have incorporated drivers for Brother printers, such as the
Brother HL-L 2320D
While not familiar at all with how one is to update packages from Github, I
am looking at the source code as well as issues during development. For
example, at this page (https://github.com/pdewacht/brlaser/issues/37), the
Brother HL-L 2320D is mentioned as being able to "duplex print" as well as
use the "CUPS server". This was mentioned on May 1 of (presumably) this year.
I am also searching through my files for any file related to "brlaser", using
keywords like "brlaser", "printer-driver-brlaser", and "ppd" in the hopes
that I may find clues about this current version of "printer-driver-brlaser"
version 3-5~ubuntu1, and whether there is any information related to my
printer.
