You seem to be conflating Linux support with FOSS support. They have nothing to do with each other.
You get a choice of a deb or an rpm packaging the following blob:
> brcupsconfpt1: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, for GNU/Linux 2.2.5, stripped
very uncommon use case...
lpadmin -p myprinter -E -v "ipp://<address>/ipp/port1" -m everywhere
The printer's web interface should give you the exact IPP/AirPrint URL to use.
