Interface
The printer is connected to a computer and prints labels according to the command from
the computer. Two systems of interface connection to a computer are shown below.
1. Serial interface: RS-232C
System Asynchronous serial interface
RS-232C
Connector DSUB 25-pin
Handshaking XON/XOFF and CTS/DTR
Receive buffer
size
32K bytes
Receiving data stops when the receive buffer reaches 2K bytes
and resumes receiving data when the receive buffer reaches
4K bytes
Baud rate 300, 600, 1200, 2400, 4800, 9600, 19200, 38400 bps
Bit length 7- or 8-bit
Stop bit Fixed
When printer is receiving data, stop bit is fixed at 1, and when
printer is transmitting data, stop bit is fixed at 2. But computer
can transmit or receive data, regardless of stop bit at 1 or 2
Parity No
2. Parallel interface: In conformity with Centronics
System 8-bit parallel
Connector 36-pin unphenol type
Synchronous system Strobe pulse
Handshaking ACKNLG and BUSY signals
Signal level TTL
