0.2mm(2.84"±0.008")(512dots) and the space on the right and left sides are

approximately 3.7 ± 2mm(0.15"±0.079").

a=79.5±0.5mm(3.13"±0.02")

b=0.141mm±0.05mm(.056"±.002")

c=72.2mm±0.2mm(2.84±.008")

d=3.7±0.2mm(0.15"±0.079")

e=3.7±0.2mm(0.15"±0.079")

[All the numeric values are typical.]

1.7 Printing and Cutting Positions

< Figure 1.2 Printing and Cutting Positions >

NOTE: Numeric values used here are typical values; the values may vary slightly as

a result of paper slack or variations in the paper. Take the notice into account

when setting the cutting position of the auto-cutter.

2. Configuration

2.1 Interface

2.1.1 RS-232 serial interface

2.1.2 Specifications

Data transmission: Serial

Synchronization: Asynchronous

Handshaking: DTR/DSR or XON/XOFF control

Signal levels: MARK= -3 to –15V: Logic “1”

SPACE= +3 to +15V: Logic “0”

Baud rage: 4800, 9600, 19200, 38400 bps

Data word length: 7 or 8 bits

Parity Settings: None, even, odd

Stop bits: 1 or more

Connector (printer side): Female DSUB-25 pin connector

NOTE: The data word length, baud rate, and parity depend on the

DIPswitch settings.

2.1.3 Switching between on-line and off-line

The printer does not have an on-line/off-line switch.

The printer goes off-line:

• Between when the power is turned on (including reset using the

interface) and when the printer is ready to receive data.

• During the self-test.

• When the cover is open.

• During paper feeding using the paper feed button.

• When the printer stops printing due to a paper-end (in cases when

an empty paper supply is detected by either paper roll end detector or

the paper roll near-end detector with a printing halt feature by

ESC c4).

• During macro executing stand by status.

• When a temporary abnormality occurs in the power supply voltage.

• When an error has occurred.
