• Enable. Allows access to the extended ASCII character set.
• Disable. The printer interprets bit 8 of each incoming data
character as a zero, regardless of its actual setting.

The PI (Paper Instruction) signal is used to control vertical paper
motion.
• Enable. Causes the printer to interpret the eight data lines as
DVFU commands when the PI signal is true.
• Disable. Ignores the PI signal and treats the data as characters or
control codes.
