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. 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 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
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.
