The interpretation of the signals in standard Centronics mode (SPP) with a printer attached is as follows:
Signal
Description
PD7..0
Parallel data bus from PC board to printer. The data lines are able to operate in PS/2
compatible bi-directional mode.
SLIN#
Signal to select the printer sent from CPU board to printer.
SLCT
Signal from printer to indicate that the printer is selected.
STB#
This signal indicates to the printer that data at PD7..0 are valid.
BUSY
Signal from printer indicating that the printer cannot accept further data.
ACK#
Signal from printer indicating that the printer has received the data and is ready to accept
further data.
INIT#
This active low output initializes (resets) the printer.
AFD#
This active low output causes the printer to add a line feed after each line printed.
ERR#
Signal from printer indicating that an error has been detected.
PE#
Signal from printer indicating that the printer is out of paper.
The printer port additionally supports operation in the EPP and ECP mode as defined in [3].
