3–40 Configuring the Printer
Host Protocol
Values: None; XON/XOFF; Series 1, 1 CH; Series 1, 2 CH.
It must be set to match your host computer.
XON means transmit on and XOFF means transmit off. In XON/XOFF protocol,
the printer sends ASCII code DC1 (Device Code 1, hex 11, XON) to the host
when it is ready to receive more data (i.e., the printer is online and the data buffer
is empty). The printer sends ASCII code DC3 (Device Code 3, hex 13, XOFF)
when it is not ready to receive data (i.e., the buffer is full or the printer is offline).
Series 1 protocol is a special protocol that sends a printer status code to the host
computer whenever the status changes. The status code is either one or two
characters with four status states defined.
The host computer can send a special “poll character” to the printer at anytime to
request the current status.
An approximate delay can be selected to determine when the status is sent back
to the host computer.
Baud Rate
Values: 110 – 115,200.
9600 is the default.
It must be set to match your host computer.
Baud rate is the number of bits, including control bits (start/stop and parity bits)
transferred per second over the interface.
Data Bits
Values: 5 – 8.
It must be set to match your host computer.
Serial interfaces support 5, 6, 7, and 8–bit transfer of data words. Most use 8–bit
data transfer, but this must match the host computer.
