Hello. hplip included questionable licensed code. File List: "prnt/hpcups/ErnieFilter.h" "prnt/hpcups/ErnieFilter.cpp" This license is "hardware specific" license. It is non-free, incompatible GPL license. This is code (software), not firmware. This problem already reported. (Debian) https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=816870 I suggest that resolve license problem. Thanks.
Created attachment 1188843 [details] Patch I removed files with proprietary license and disabled features using it (PCL3GUI2). Package was built in RAWHIDE.
