So... yeah, I guess we're saying that your printer was 5 years old at the
moment you bought it.  Or at least, that it was a 5-year-old *design*,
even if that particular printer had been assembled more recently.


The Brother HL-L2320D seems to have come on the market in early
2016. I haven't any idea when Staples decided to stock it.


Now, personally I don't consider a 7-year-old product to be an antique,
but maybe Brian does.  I certainly can't speak for him on this topic.


I do not consider a 7-year-old product to be an antique. The
significance of 2016 is that it is four years after the
IPP-over-USB standard was ratified.

Network printers from 2016 almost certainly (always in my
experience) do ship with IPP-over-USB. For some reason USB-only
devices generally do not provide it; it's very hit-and-miss.

I do not know why all vendors (not just Brother) have taken that
decision. It's a real pain as it effectively makes the printer
a legacy model and very much limits how it fits into the Debian
printing ecosystem.
The big scanner/printer has an ip address, but its a lot slower when using ipv4 to operate it, I wiresharked it back about jessie, and found why, the cups driver for IPP was sending a bad crc the first 6 times it tried to wake it up before it decided to send a good crc, so there was a 1 minute time killer just to wake it up. Then it was about a 5 kilobaud circuit, about a minute a text page. Its at least 5x faster on a usb2 circuit. A ping works in 0.5 milliseconds, but that doesn't wake it up. Its much faster on a usb circuit.
I made some noise about it at the time, but was ignored. I don't know if dfu could update its firmware, or if its too old for that. 

Cheers, Gene Heskett.
