I imagine, if my, say $60000 in bank account turn to $80000.
Or, if when i print electronic ticket, flight FLIGHT-606 at 16:06 16 OCT 2013 switches to flight FLIGHT-808 at 18:08 18 OCT 2013.

Here, one guy complains that he had similar problem, when he printed electronic ticket for railway out of PDF file. Some symbols and numbers have changed.

Oh no. Copiers are even more dangerous, than i thought before.
They log everything that passes through them.

Watch.
