bchemnet, take a look at HP 107 drivers. This is a new HP device, but it is made on the same hardware and software platform as Samsung Xpress SL-M2020 and also uses SPL with uld driver.
The latest driver available for this device is V1.00.39:00.12_00.15 from Jun 26, 2020. The archive includes i386, amd64, aarch64 and mips64 binary libraries.

The configuration files are all stripped for HP, but I won't be surprised if it would work with Samsung printers by just copying oem.conf and smfp.conf from the Samsung uld.
