Specification
(STANDARD)
NOTE: 1.A prefix “n” to signal names refers to “L” active signals. To the host provided with none
of 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 shall be all based on the TTL level to meet the characteristics
described below. In addition, both rise time and fall time of each signal shall be
0.5ms 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 “L” level.)
5.Interface cables shall be as minimum required short in length as possible.
*NC: No Connect
ND: Not Defined
6.When the DTR/DSR control is selected, the printer becomes the BUSY state under the
following conditions.
DIP SW 2-1 status
Printer status ON OFF
1. Durin
the period from when the power is turned on
(includin
resettin
usin
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 printin
due to a paper-end. (onl
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.
BUSY BUSY
NOTE: 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.
