PRINTER MODE:
An active-high input on this pin indicates that the printer is selected.
See the description of the parallel port for the definition of this pin in
ECP and EPP modes.
PRINTER MODE:
An active-high input on this pin indicates that the printer has detected
the end of the paper. See the description of the parallel port for the
definition of this pin in ECP and EPP modes.
PRINTER MODE:
An active-high input indicates that the printer is not ready to receive
data. See the description of the parallel port for the definition of this
pin in ECP and EPP modes.
PRINTER MODE: ACK#
An active-low input on this pin indicates that the printer has received
data and is ready to accept more data. See the description of the
parallel port for the definition of this pin in ECP and EPP modes.
PRINTER MODE: ERR#
An active-low input on this pin indicates that the printer has
encountered an error. See the description of the parallel port for the
definition of this pin in ECP and EPP modes.
PRINTER MODE: SLIN#
Output line for detection of printer selection. See the description of
the parallel port for the definition of this pin in ECP and EPP modes.
PRINTER MODE: INIT#
Output line for the printer initialization. See the description of the
parallel port for the definition of this pin in ECP and EPP modes.
PRINTER MODE: AFD#
An active-low output from this pin causes the printer to auto feed a
line after a line is printed. See the description of the parallel port for
the definition of this pin in ECP and EPP modes.
Diskette Change. This signal is active-low at power-on and
whenever the diskette is removed. This input pin needs to
connect a pulled-up 1-KΩ resistor to 5V for Floppy Drive
compatibility.
General purpose I/O port 6 bit 0.
