6.2Interface

The printer is connected to a computer and prints labels according to the commands from the computer.

Two methods of interface with a computer are as follows:

6.2.1Serial interface system configuration Serial interface: RS-232C (standard)

Serial interface specifications

 

 

Method

Asynchronous serial interface

 

 

RS-232C

 

 

Connector

DSUB 25-pin

 

 

Protocol control

XON/XOFF and CTS/DTR

 

 

Receive buffer size

12K bytes

 

 

Receiving data stops when the receive buffer reaches 2K bytes

 

 

available and resumes when the receive buffer reaches 4K bytes

 

 

available

 

 

Baud rate

300, 600, 1200, 2400, 4800, 9600, 19200, 38400 bps

 

 

Bit length

7- or 8-bit

 

 

Stop bit

Fixed

 

 

When printer receives data, stop bit is fixed at 1, and when

 

 

printer transmits data, stop bit is fixed at 2. But computer can

 

 

transmit and receive data, regardless of stop bit at 1 or 2

 

 

Parity

Non
