An old post from Bill inspired me to re-create the topic which is a good thing to do whenever a topic is more than 30 days old. Creating new topics makes sure the material is noticed by new visitors to the Forum and is recent.
Anyway, I found this searchable listing (https://openprinting.org/drivers) for Linux-compatible printers at the website Open Printing (https://openprinting.github.io/about-us/) which is a group under the Linux Foundation that works on printer support under Linux.
