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.
