PRINTER MODE:
An active high input on this pin indicates that the printer is
selected. Refer to the description of the parallel port for definition
of this pin in ECP and EPP mode.
PRINTER MODE:
An active high input on this pin indicates that the printer has
detected the end of the paper. Refer to the description of the
parallel port for the definition of this pin in ECP and EPP mode.
PRINTER MODE:
An active high input indicates that the printer is not ready to
receive data. Refer to the description of the parallel port for
definition of this pin in ECP and EPP mode.
PRINTER MODE: ACK#
An active low input on this pin indicates that the printer has
received data and is ready to accept more data. Refer to the
description of the parallel port for the definition of this pin in ECP
and EPP mode.
