35.5 lps maximum (4.23 mm {1/6"} feed) (at 24V, 28°C {82.4°F}, Density level 1. Speeds are switched
automatically depending on the voltage applied to the printer and head temperature conditions.)
Low power consumption mode: Approximately 16.5 lps (4.23 mm {1/6"} feed) Approximately 70 mm/s {approximately 2.76"/s}
When a ladder bar code is printed: Approximately 42 mm/s {approximately 1.7"/s}
[lps: lines per second]
NOTES: • There may be variations in printing after switching the mode of the printing speed. To
prevent this for logo printing with ESC ∗∗∗∗ command, using a downloaded bit image is recommended. Change in printing speed does not occur during down loaded bit image printing.
• Printing speed may be slower depending on the data transmission speed and the
combination of control commands.
• Low transmission speed may cause intermittent printing. It is recommended to transmit
data to the printer as quickly as possible.
• High speed mode or low power consumption mode is selected by a DIP switch. (Refer to
Table 3.3.4 and 3.3.7).

• If the DIP SW2- 5 is on, when the remaining spac e in the receive buffer drops to 128 bytes, the printer status becomes “buffer full” and it remains “buffer full” until the space in the receive buffer increases to 138 bytes.
• When the receive buffer capacity is specified to 45 bytes (DIP SW1-2 is On):

2.1.1.6 Notes on setting DIP switch 2-1 to ON
1) The printer mechanism stops but does not becom e busy when: an error has occ urred, the c over is open, printing stops due to a paper-end, or paper is fed using the paper feed button.
2) W hen setting DIP switch 2-1 to ON to enable handshaking with the printer, be sure to chec k the printer status using the GS a command and the ASB function. In this setting, the default value of n for GS a is 2. The printer autom atically transmits the printer s tatus, depending on online/offline changes.
3) When using DLE EOT, DLE ENQ, and DLE DC4 be sure that the receive buff er does not becom e full.
• When using a host that cannot transmit data when the printer is busy: If an error has occurred, DLE EOT, DLE ENQ , and DLE DC4 cannot be us ed when the printer
is busy due to a receive buffer-full state.
• When using a host that can transmit data when the printer is busy: W hen the receive buffer becomes full while transmitting bit-im age data, DLE EOT, DLE ENQ
or DLE DC4 used while sending the bit-image data is processed as bit-im age data. The data transmitted when the receive buffer is full may be lost.
Example: Check the printer status using GS r after transmitting each line of data and use
the 4 KB receive buffer. Transmit one line of data so that the receive buffer does not become full.
2.1.1.7 Notes on Resetting the Printer Using the Interface

8) When an error has occurred.
2.1.2.2 Reverse Mode (Data Transmission from Printer to Host)
The STATUS data transmission from the printer to the host is proceeded in the Nibble or Byte mode.
• Description This mode allows data transmission from the asynchronous printer under the control of the host. Data transmissions in the Nibble Mode are made via the existing control lines in units of f our bits
(Nibble). In the Byte Mode, data transmissions are proceeded by making the eight-bits data lines bidirectional. The both modes fail to be proc eeded concurrently with the Compatibility Mode, thereby causing half duplex transmission.

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
0.5 µs 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.)
