  The technology has changed but the idea lingers on... a PC virus
making the rounds monitors printer output, and when it detects a string
of digits adds or subtracts one to a random digit. Lovely if the text is
a check or tax return.

  I once had a printer which had an out of spec cable (over length by
about 400%) and which would drop the least significant bit of the
character following the @ character. A set of hand wired terminating
resistors was added.
