I'm sure there are probably better ways to do this, but the following
may help:

    (let ((ps-options '("-u\"Joel J. Adamson\""
                        "--ul-font=Times-Roman100")))
      (apply 'concat
             (apply 'append
                    (mapcar (lambda (s)
                              (list s " "))
                            ps-options))))

    => "-u\"Joel J. Adamson\" --ul-font=Times-Roman100 "
