If this does not help, it looks like that "make install" has put the Fax PPDs to the wrong place during package build.
Please set up your printer with system-config-printer to work around this problem.
Suggestion to improve upstream HPLIP: Please do not rely on absolute paths for the Fax PPDs. Use the auto-assignment of PPDs of CUPS. The hpfax backend and the PPDs have the correct (matching) device IDs for that.
First, everyone who has this problem, please do
rm -rf ~/.hplip
and try again.
