I cannot reproduce this with 

        Emacs 21.1, X11, GNU/Linux
        emacs -q -no-site-file
        M-x load-file <ret> ps-print <ret>
        M-x customize-option <ret> ps-paper-size <ret>
        Change "letter" to "kurt"
        Push mouse-2 on [Set for Current Session]

I get a nice error message "Unknown paper size".

It is true that the cursor doesn't move, though.
