Data is first applied on the Parallel Port pins 2 to 7.
The host then checks to see if the printer is busy.
i.e. the busy line should be low. The program then
asserts the strobe, waits a minimum of 1uS, and then
de-asserts the strobe. Data is normally read by the
printer/peripheral on the rising edge of the strobe.
he printer will indicate that it is busy processing data
via the Busy line. Once the printer has accepted data,
t will acknowledge the byte by a negative pulse about
uS on the nAck line.
