Parallel Interface
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. 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.
