1. ACK/ will not go high until STROBE/ goes high.
2. When the printer is not ready to receive more data, ACK/ will be sent, but BUSY will
remain high.
3. When the power is turned on or the printer is reset, an ACK/ will be sent during
initialization.
4. Typical time from STROBE/ to ACK/ is approximately 44 µ seconds.
