Interface Parameters
The interface parameters are values associated with serial communi-
cation interfaces. When using a serial interface, these parameters
must be set to correspond to the capabilities of the host computer and
the interface.
The following figure shows the interface submenu and the following
paragraphs describe the interface setup parameters.
Port
The port submenu lets you choose the correct communication
interface port, depending on whether you are using a serial, parallel,
or optional interface. The default setting is SERIAL.
Buffer Size
The buffer size specifies the number of data bytes that the printer’s
receive buffer can store. The buffer size parameter can be set to 256,
4000, or 32,000 bytes. The default setting is 32,000.
