I'm surprised that this guy had no choices other than paper tape and punched cards. In 1980! Around that time I saw machine rooms filled with line printers and magtape decks; sometimes there might be a card reader or paper-tape reader. But I never saw these devices outside of a machine room; they were for use by the operators. Everone else used terminals ("glass teletypes").
