reset_waste_ink not working for ET-4800 on Mac.

[futurechan]

I am trying to run --reset_waste_ink, and I am getting Invalid read key..

Here are some details:

When I run epson_print_conf without a specific function:

Failed to reset waste ink levels. Check configuration.

If I run --detect_key, it does not find a key.

Software version
5.3.6 - I pulled master and am running the python directly.

Additional context
I am on Mac OS 14.x.

This printer supports a new firmware that disabled SNMP EEPROM management.
