printing -- Manjaro ARM KDE plasma

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 have a similar printer.  It seems to work better via wireless with just the "Generic" printer type, and either ipp or lp as the connection type.  Then it's just the ip address for the URI (at least for me).  Printing works fine on mine once you get it set up.
