Every Cognitive layout must have an END command at the conclusion of the layout. END is on a separate line at the end of the Cognitive layout and must be followed by a new line character (carriage return). To place a new line character after END, simply press the Return or Enter key on the keyboard. If END is not at the end of the Cognitive layout, the tickets or vouchers do not print. If the END command is not followed by a new line character, the tickets or vouchers print every other time.
