It seems you ran into bug #1371294 https://bugzilla.redhat.com/show_bug.cgi?id=1371294 . I'll look into it. Closing this as duplicate. *** This bug has been marked as a duplicate of bug 1371294 ***
Kakoskin, would you mind running commands and sending me outputs/files: 1) /var/log/cups/error_log (you need to set ErrorLog to /var/log/cups/error_log in /etc/cups/cups-files.conf ) when sigsegv happened 2) hp-check 3) hp-probe 4) hp-setup -i (this will run hp-setup in interactive mode)

I hit this bug originally while printer was not connected but I just tested and I hit same crash even when the printer is plugged in. I hit SeLinux denial https://bugzilla.redhat.com/show_bug.cgi?id=1398277 while running hp-probe with printer connected.
