Joining the array to form a string should avoid the need for a print,
allowing the #-o to apply to the string as a whole. E.g:
typearg=${${(j. .):-'-o -type '${^types:#-t}}#-o }
Shorter versions should be possible such as the following:
typearg="${${=types//-t/-o -type}[2,-1]}"
I'd be inclined to keep typearg as an array, however.
