Even if you choose the automatic interface selection, you need to set the
communications parameters for the serial interface, high speed/bi-
directional communications for the parallel interface, and the optional
interface settings if the installed MIO card requires them. See the tables
below.
For further information about automatic interface selection,
see "AUTOMATIC INTERFACE SELECTION" in Chapter 3.
Parallel Interface
When you intend to use the bi-directional parallel interface, select the
interface on the display as follows:
I/F=PARALLEL
When you use the parallel interface, you need to set the communications
mode in the following sub-setting menu.
Display Message
HIGH SPEED=ON
BI-DIR=ON
The above high-speed and bi-directional settings are used for the
bi-directional parallel interface of this printer. The bi-directional parallel
interface is compatible with the IEEE 1284 standard bi-directional parallel
interface. Although it uses the same cable, hardware, and software as the
bi-directional parallel interface, to use its enhanced capabilities—such as
bi-directional communication between the computer and printer and faster
transmission of data—you need a printer driver or software that supports
these features. Check with your software vendor to see if your software
supports bi-directional parallel features.
Serial Interface
When you intend to use the serial interface, be sure to select the same
communications parameters on both the printer and computer. You must
set them for the automatic interface selection, too.
