Download the PPD printer configuration from Kyocera as the FS-4020DN is not include in the foomatic or openprinting PPDS. Note that the vendor page offers two downloads.
- Linux UPD driver with extended feature support
- Linux PPDs
The UPD driver has binary installers for a variety of Linux distros but the binaries are x86 or x86-64. The included PPD references binary CUPS filters that will not run on ARM. In contrast the PPD drivers once extracted are entirely usable.
