down 100k Ω ).
F81867
GPIO71
I/OOD_12st,
General purpose IO.
5v
An active high input indicates that the printer is not
104
3VCC
ready to receive data. Refer to the description of the
BUSY
IN_st,5v
parallel port for definition of this pin in ECP and EPP
mode.
GPIO72
I/OOD_12st,
General purpose IO.
5v
An active low input on this pin indicates that the
105
3VCC
printer has received data and is ready to accept more
ACK#
IN_st,5v
data. Refer to the description of the parallel port for
the definition of this pin in ECP and EPP mode.
GPIO73
I/OOD_12st,
General purpose IO.
5v
106
3VCC Output line for detection of printer selection. Refer to
SLIN#
I/OOD_12st,5v
the description of the parallel port for the definition of
this pin in ECP and EPP mode.
GPIO74
I/OOD_{12st, 5v}
General purpose IO.
Output line for the printer initialization. Refer to the
INIT#
I/OOD_12st,5v
description of the parallel port for the definition of this
pin in ECP and EPP mode.
107
3VCC
PWM0 Output where its frequency range is
PWM0
OOD_{12st, 5v}
183Hz~46.875KHz. It can support various
applications such as manual fan control, and
backlight brightness control.
GPIO75
I/OOD_{12st, 5v}
General purpose IO.
An active low input on this pin indicates that the
ERR#
IN_st,5v
printer has encountered an error condition. Refer to
the description of the parallel port for the definition of
108
3VCC this pin in ECP and EPP mode.
PWM1 Output where its frequency range is
PWM1
OOD_{12st, 5v}
183Hz~46.875KHz. It can support various
applications such as manual fan control, and
backlight brightness control.
GPIO76
I/OOD_{12st, 5v}
General purpose IO.
An active low output from this pin causes the printer
AFD#
I/OOD_12st,5
v
to auto feed a line after a line is printed. Refer to the
description of the parallel port for the definition of this
pin in ECP and EPP mode.
109
3VCC _{PWM2 Output where its frequency range is}
183Hz~46.875KHz. It can support various
PWM2
OOD_{12st, 5v}
applications such as manual fan control, and
backlight brightness control.
