(STANDARD)
NOTES: 1. A prefix “n” to signal names refers to “L” active signals. If the host does not provide all of
the signal lines listed above, both-way communication fails.
2. For interfacing, signal lines should use twisted pair cables with the return sides
connected to signal ground level.
3. Interfacing conditions all must be based on the TTL level to meet the characteristics
described below. In addition, both rise time and fall time of each signal must be
0.5 µs or less.
4. Data transmission should 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 should be made after verifying the nAck signal or while the Busy signal is at
the “L” level.)
5. Interface cables should be at least the minimum required length and as short in length
as possible.
6. When the DTR/DSR control is selected, the printer enters the BUSY state under the
following conditions.
DIP SW 2-1 status
Printer status ON OFF
1. During the period from when the power is turned on (including
resetting using the interface) to when the printer is ready to
receive data.
BUSY BUSY
2. During the self-test.
BUSY BUSY
3. When the cover is open.
— BUSY
4. During paper feeding using the paper FEED switch.
— BUSY
5. When the printer stops printing due to a paper-end (only when
the paper roll is not present).
— BUSY
6. During macro executing standby status.
— BUSY
7. When an error has occurred.
BUSY
8. When the receive buffer becomes full. (*1)
BUSY BUSY
*1: When the remaining space in the receive buffer drops to 16 bytes, the printer
status becomes “buffer full” and it remains “buffer full” until the space in the
receive buffer increases to 26 bytes.
