Two lines of text are printed, respectively, by print heads 1 and 2 on record card 3, contemporaneously with the magnetic recording by head 4 of related data on magnetic stripe 5. To minimize disturbance of the continuous feed motion of card 3, which disturbance would interfere with valid recording, print heads) and 2 are operated by control unit 6 to print alternately, rather than simultaneously. The print heads 1 and 2 are physically offset by a character width 7 to align the characters of the two lines of text.
