Removing those packages should not have made a difference.  Maybe all you
needed was a restart.

I don't think you need those apple.* files.  URF support is already included
in /usr/local/share/cups/mime/cupsfilters.*.

Something else you might want to check in /usr/local/etc/cups is if there
are any differences between configurations files and their corresponding
*.sample file and if those differences still make sense.
