The 7193 uses a standard PC-compatible parallel interface. The following
illustration shows the timing diagram for the interface protocol.

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.
