Hi,
According to the specifications, only Windows and Linux are supported.

Results from Search - Apple Community indicate that workarounds may be possible, but a patch seems to be involved in some cases. Be careful. Generally speaking, it is not wise to get files from unknown sites. Always download from a trustworthy source, such as Apple or the printer manufacturer.
If necessary, since CAPT drivers for Linux are available, you may want to carry out an experiment with an old (spare) PC running an earlier version of the free Ubuntu. The idea would be to connect the local USB printer to the PC, and then share this printer on a network. Ubuntu uses CUPS and understands Bonjour. Sharing a printer in Ubuntu will just require a few changed settings in the CUPS (web) interface. A Mac connected to the network ought to be able to see and use the shared printer.
