PRINTER MODE: ERR#
An active low input on this pin indicates that the printer has
encountered an error condition. This pin is pulled high internally.
Refer to the description of the parallel port for the definition of this pin
in ECP and EPP mode.
EXTENSION FDD MODE: HEAD2#
This pin is for Extension FDD B; its function is the same as the
HEAD#pin of FDC.
EXTENSION 2FDD MODE: HEAD2#
This pin is for Extension FDD A and B; its function is the same as the
HEAD# pin of FDC.
PRINTER MODE: SLIN#
Output line for detection of printer selection. This pin is pulled high
internally. Refer to the description of the parallel port for the
definition of this pin in ECP and EPP mode.
EXTENSION FDD MODE: STEP2#
This pin is for Extension FDD B; its function is the same as the
STEP# pin of FDC.
EXTENSION 2FDD MODE: STEP2#
This pin is for Extension FDD A and B; its function is the same as the
STEP# pin of FDC.
PRINTER MODE: INIT#
Output line for the printer initialization. This pin is pulled high
internally. Refer to the description of the parallel port for the
definition of this pin in ECP and EPP mode.
EXTENSION FDD MODE: DIR2#
This pin is for Extension FDD B; its function is the same as the DIR#
pin of FDC.
EXTENSION 2FDD MODE: DIR2#
This pin is for Extension FDD A and B; its function is the same as the
DIR# pin of FDC.
PRINTER MODE: AFD#
An active low output from this pin causes the printer to auto feed a
line after a line is printed. This pin is pulled high internally. Refer to
the description of the parallel port for the definition of this pin in ECP
and EPP mode.
EXTENSION FDD MODE: DRVDEN0
This pin is for Extension FDD B; its function is the same as the
DRVDEN0 pin of FDC.
EXTENSION 2FDD MODE: DRVDEN0
This pin is for Extension FDD A and B; its function is the same as the
DRVDEN0 pin of FDC.
