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.
