Well, this blog post convinced me that upgrading from bullseye to bookworm didn't have to be nearly as complex as the official Debian documentation made it out to be, so I followed those instructions and completed without error. Initially, I neglected to edit /etc/apt/sources.list.d/armbian.list before executing full-upgrade, but it seems to have worked as a two-step full-upgrade.
Welcome to Armbian 23.8.3 Bookworm with Linux 6.1.53-current-sunxi and xradio wifi is working 😀

use armbian-config to freeze firmware packages. Then they will not be upgraded on regular apt upgrade.

Yeah, just noticed this myself.
 
I was pleased that Armbian 23.05 started up just fine on my Orange Pi Zero (H3 LTS), seeing as other discussions had said that Allwinner 32bit was not working.
 
Wireless is definitely not working OOTB, however. I updated firmware in armbian-config, but the Networking options don't show a wifi option. Neither ifconfig nor nmtui-connect list a wireless interface. No messages from xradio in dmesg.
 
I think maybe I saw a mention in an old forum post that the xradio driver doesn't work with kernel 6.x, so maybe that's it? Or maybe it's just not set up quite right? Or maybe there's something that users need to do in order to get it working?
 
In spite of the terrible reputation of the xradio driver, it was working adequately for me in Armbian bullseye. Very much hope that I can get it working in latest Armbian!

I described my connection poorly; I'm actually not using the wifi on the OPi. It has an ethernet connection to my router, and the router connects to the printer over wifi. So as far as the OPi is concerned, it's an ethernet connection.
 
Anyhoo! Yes, printing over USB works . I can't readily connect the OPi directly to the printer via ethernet, since OPi's ethernet is how it connects to the local network. But I did try connecting the printer to the router on ethernet (rather than wifi), and it works . And then when I took the printer off ethernet and back on wifi, leaving CUPS with the same configuration, it continues to work ! Only thing I can see that might be different is that, when connected on ethernet, I had CUPS use LPD instead of DNSSD. Don't remember if I had tried that previously. Even at that, I still had to manually edit /etc/cups/printers.conf to to put the printer's static IP in the device URI, in place of the "friendly" name that CUPS had selected. So this whole thing is probably 100% user error/inexperience. Thank you @Tido @usual user @martinayotte so much for your help and your patience with me!
