NOTES:
1. A prefix “n” to signal names indicates LOW active signals. To the host not provided with the signal lines listed
above, both-way communication fails.
2. For interfacing, signal lines shall use twisted pair cables with the return sides connected to signal ground level.
3. Interfacing conditions all shall be based on the TTL level to meet the characteristics described below. In
addition, both rise time and fall time of each signal shall be 0.5
µ
s or less.
4. Data transmission shall not ignore the signal nAck or Busy. An attempt to transmit data with either signal, nAck or
Busy, ignored can cause lost data. (Data transmissions to the printer shall be made after verifying the nAck signal
or while the Busy signal is at the LOW level.)
5. Interface cables shall be the minimum length required and as short in length as possible.
