Did you try searching for CUPS packages with Pamac?
Launcher > System > Add/Remove Software

Thank you for the suggestion. Pamac lists cups package successfully installed, nothing missing.
Several forum members have pointed me toward Airprint as an all purpose generic driver. I can't find where to employ it. CUPS wants a ppd file. I have downloaded two ppd files from openprinting.org (thanks to a suggestion) that are supposed to work with Brother HL-L2340DW, but the print job hangs up with "filter failed" message.
The Bonjour (modern) method of connecting requires a printer URI which I can get with the lprint command. But, that command has a dsnsd parameter which I don't seem to have.
My printer has wifi capability, but I have been trying to connect through USB. It should work either way. The printer connection instructions in Debian and Arch forums are clear and simple. Is puzzle.

i recently installed brlaser or brlaser-git using yay for my HL-L2330, connected via SUB. The driver installed was 2300 or something equivalent to 2330.
