HOST INTERFACE

Serial Submenu

IMPORTANT
The serial parameters in the printer must be set the same as the serial
interface in the host computer. Otherwise, the printer might not work
online, and data characters from the computer might not print or might
print as "garbled" text.

The serial submenu allows you to choose the configuration of the Serial host
interface type, as shown above. Several other serial parameters are included
on this menu, as shown below and described in the following pages.
Interface Type
Allows you to select either the RS-232 (the default) or RS-422 serial port
interface.
Data Protocol
You can select one of the following serial interface protocols to meet the host
interface requirements.
•
XON / XOFF. The default. The printer controls the flow of communication
from the host by turning the transmission on and off.
In some situations, such as when the buffer is full or the timing of signals
is too slow or too fast, the printer will tell the host to stop transmission by
sending an XOFF character.
An XOFF character is sent when the number of empty bytes in the buffer
is less than or equal to 25 percent of the buffer size.
